Work about to start in St Nick’s Covered Market, Bristol!

in ,

gcp has been working with a fantastic team at Bristol City Council to reimagine the central area of the Grade 2* Listed Covered Market in the highly popular St Nicholas Markets.

The Covered Market has not enjoyed the same footfall as other parts of the market; the scheme therefore provides a new destination to encourage visitors to experience the market in its fullness.

The scheme plays with structure, materials, and recesses to create a finely balanced proposal which achieves both commercially viable floorspace and breathing space to a previously cramped site.

Our Declaration of Carbon Neutrality

in

Reducing our environmental impact has always been a key consideration in our design work. From delivering the UK’s first BREEAM Excellent sports centre in 2000, to becoming Passivhaus certified in 2007, and most recently generating whole life carbon assessments in 2019.

We are used to talking the talk, but in 2023 we decided it was time to walk the walk. Through our Employee Council we floated the idea of measuring our own carbon impact with a view to reducing carbon emissions as far as possible and becoming carbon neutral.

We reviewed various certification schemes and assessment methodologies including B-Corp, PAS 2060 and EcoVadis. The pros and cons were discussed in the Employee Council before a report was prepared for the Board. We settled on PAS 2060 as our methodology for measuring carbon emissions, creating a carbon reduction plan, and offsetting.

We can now release our Declaration of Carbon Neutrality for 2022-2023.

During this time, we reported on our Scope 1 and Scope 2 emissions, alongside Scope 3 emissions for transport. Scope 1 relates to on-site emissions, e.g. gas boilers. Scope 2 relates to off-site emissions for energy used on-site e.g. electric boiler. Scope 3 covers all other emissions on and off site including relevant upstream and downstream emissions.

Our total carbon footprint for 2022/23 was 6.2tCO2e, split into 44% Scope 2 and 56% Scope 3 emissions.

Over our historic reporting period our Scope 2 emissions have reduced year on year due to:

  • Installing an efficient HVAC unit with heat recovery to reduce carbon emissions through ventilation as well as improving office air quality.

  • Changing all office lighting to better performing LED fittings.

  • UK grid decarbonization.

In the same period our Scope 3 emissions fell sharply due to COVID, but also due to:

  • Encouraging staff to cycle where appropriate to reduce travel emissions.

  • Reducing the number of on-site meetings where not necessary.

  • Encouraging low carbon transport methods where possible.

Whilst 2022/23 saw an increase in Scope 3 emissions from 2020/21 and 2021/22 this is primarily due to an increase in staff numbers alongside business returning somewhat to the pre-COVID norm. Ignoring the impact of COVID, our Scope 3 emissions have reduced by 46% from our 2018/19 base level. This is demonstrated by the graph below.

Whilst we continue to reduce our carbon emissions, there will always be a need to offset the remaining emissions to achieve carbon neutrality. As such from 2022 we started a tree planting program.

Initially our tree planting was based on a will to do the right thing rather than data, but now we report against PAS 2060 we are monitoring how many trees should be planted annually to cover our emissions.

Our offsetting strategy is based on Pending Issuance Units (PIUs) for predicted growth of saplings rather than Woodland Carbon Units (WCUs) which cover sequestered carbon in mature woodland. gcp will monitor the survival rate and growth of the trees over the next reporting period to accurately monitor the carbon absorption.

In February 2024 gcp planted 160 trees to offset our carbon emissions for the 2022/23 reporting period. This equates to approximately 160 tonnes of carbon over the lifetime of the trees. This is far greater than what was required to offset our 6.2 tonnes of carbon emissions for the reporting period, but overachieving with PIUs allows us to achieve a real-world carbon break even point as soon as possible.

This is demonstrated in the graph below:

This demonstrates our predicted carbon emissions over the next 30 years against the real-time carbon offsets through tree planting. We can forecast that from the start of our reporting period we will be carbon neutral by 2044.

Extrapolating this in both directions, which includes a lot of assumptions, we can approximate that gcp will be carbon neutral for all emissions since conception in 1987 by 2061.

The Value of Competitions: Midland Road | Bristol

in ,

Background

In July 2023, Brighter Places in partnership with the Bristol Housing Festival launched a design competition, for a new affordable development within Bristol City center.

Midland Road is a prominent local centre, adjacent to Old Market and previous home to a paintworks, since demolished. The brief was to provide a 100% affordable / social rented development of up to 70 units.

Having previously worked with Brighter Places, our aim was to create both a destination location within the wider local community, and a design that sensitively responds to its local context and needs.

Process

For this scheme an understanding of local and broader contexts was key. We began by reviewing the typology and scale of the surrounding environment, the sites’ access to green spaces and the overall local transport links.

From this we recognized that Midland Roads presents a unique focus point of transport links, creating an idealized meeting place for residents & passers alike, with opportunity for commercial / community led interventions.

Similarly, our initial studies identified a lack of local green space links (both public and private). These spaces are critical to community growth & function, as such the provision of accessible green space was critical to the design.

Understanding the immediate context was also key. Surrounding structures presented a high density of 5+ stories, with a mostly industrial context, infilled with more modern midrise housing developments.

Our initial Massing would follow the relatively limited footprint of the site, whilst cutting out key foot / cycle connections to permeate the structure and allowing for a central courtyard to create meeting and commercial opportunities.

Looking at the opportunities & constraints available to us, we quickly identified 3 key strategies to develop:

  1. Green Spaces for all: green spaces are often a luxury in urban centers. Our aim was to create a mixture of both public and private green spaces within the scheme, by using the roofs as interconnected terraces to create over 900sqm of space for residents & a ground floor courtyard for the public.

  2. Fostering Community: modern housing often lacks community, with disconnected structures and sterile circulation. Our aim was to create a winding path laced with social spaces throughout the structure that then further connected to proposed green spaces. The aim was to create an interconnected set of communal streets to enhance interaction.

  3. Activated Streets: The site is uniquely located at the intersection between transport links, from foot to local buses. This presents the opportunity to create a local hub, the proposal would need to be open in nature, with ground floor uses that would encourage residents and non-residents alike inside.

The Design

The final design appeals to the industrial character of the site, using an exposed frame with infill patterned brick panels. The mass is broken down by circulation cut through’s at ground level, and circulation at upper levels, conjunction with the perforated forms of the flats this gives the structure a high degree of permeability. The structure itself steps down with the context, beginning with 10 stories, gradually reducing to 6 stories.

Starting at the ground level is a mixture of public courtyards and commercial units, moving up the structure is a winding path of private roof gardens & circulation paths, each flat within the block has to move up or down a maximum of one storey to access a green space.

Each flat has its own balcony, and by mixing walk up and same storey accesses, there is only a singular circulation corridor per 2 levels of flats, maximizing social opportunities to shared areas.

 

The Submission

The final design was submitted in August. Unfortunately, gcp were not selected for the final shortlist this time. Designing a dense urban proposal in the center of Bristol was both invaluable and enjoyable; an experience that we can take with us into future projects.

End of Year Wrap Up: 2023

in

After a successful 2022, we started 2023 on a high, determined to build on last year’s key themes of collaboration, team work and supporting the next generation of designers and architects.

In January, we ran a workshop in a local primary school, where we helped the students think about the design of an outdoor education space. Later in the year, we had a year 10 work experience student join us for the week.

We also celebrated Owen Faunt graduating from his Architectural Assistant Degree Apprenticeship in May, Sarah Makroum completing her RIBA Part 2 qualification, Hazel Momberg becoming a chartered member of CIAT and Matt Taylor completing his RIBA Part 3 to become a fully qualified architect.

This year a key focus for us has been sustainability. We have been invited to lead seminars to help others understand Whole Life Carbon, emerging policy and specifics relating to their own projects. We can now undertake Whole Life Carbon Assessments to help with target setting and reporting – get in touch if you would like to know more!

Several of our construction projects have wrapped up in 2023, including all-but-one phase of Century Park, Lawrence Weston, phase 1 of Oakfield in Swindon, phase 2 of Margaret Bondfield Close in Pilton, the refurbishment of three tower blocks on Silcox Road in Bristol, and the Swimarium in Westbury.

gcp have always had a strong portfolio of housing projects and we have finished this year on another high: achieving planning permission on sites including a rural exception site in the Forest of Dean and conversion of a warehouse to apartments in Bristol.

In June we achieved planning for Walwyn Gardens, a scheme that finally achieved planning after a two-year wait. This retrofit scheme includes demolishing and replacing existing leaking courtyard access walkways with contemporary, thermally improved communal access routes. All windows and doors will be replaced as well as a new colour palette introduced to the reclad corridor elements. Construction work has now begun.

Two years of design and consultation with a team of environmental consultants culminated with unanimous support of the South Gloucestershire Development Committee of our proposals for extensions to the McBraida Aerospace engineering works at Bridgeyate, Bristol. This marks a significant milestone in the McBraida company’s long-term plan to expand and modernize their UK headquarters. We were thrilled to be part of the team helping the expansion plan to succeed.

It had been a while since gcp had entered any big competitions, but we loved the look of Bristol Housing Festival’s Nover’s Hill.

Nover’s Hill is a ecologically constrained site and the brief was for a sustainable development with high biodiversity. Through careful analysis of the levels, the existing trees, the views and the pond we created a high density housing scheme which promoted large amounts of public and private amenity spaces, natural light and ventilation.

Entering more competitions was a 2023 aspiration for our team, so we thought we’d give it a go. We were thrilled to win the competition!

We will be working on developing the scheme in more detail for Goram Homes in 2024.

Back with our team, we continued to focus on mental health and wellbeing, using National Work Life Week and Mental Health Awareness Week as part of our annual diary, not just because they support our company values, but because they allow us to report, refocus, review our polices and remind ourselves regularly to check in with each other.

This year we planted sunflowers, made art together, took some forest walks, went to the café as an office and played board games. These events gave importance to taking a break, having some fun and connecting with our colleagues. We are just finishing up our advent of December games, where we take a few moments each day to be silly and enjoy some friendly competition.

It's been another busy year for gcp. We took some time at the beginning of December to enjoy a Christmas meal together in Keynsham and will hold farewell drinks for Martin Spear on Thursday, when he retires after 35 years of wonderful service. He will be sadly missed, but we wish him well on his next adventure.

It’s exciting to welcome more talent and experience to our growing team. Esther Slade, Jenny Gossage, Tim Oswald, Tina Vasilache and Richard Glass joined us in 2023 and we have one more new starter joining us in the New Year.

We can’t wait to see what is in store for us and for you, in 2024.

Season’s greetings to all and wishing you a very happy New Year.

Planning consent for first zero-carbon clubhouse in the UK!

in ,

This small project in Bristol for Downend & Frenchay Tennis Club brings together two of gcp’s passions: sport and sustainability. From conversations with the Lawn Tennis Association (LTA), we believe this is the first LTA-affiliated clubhouse in the country to be designed as zero-carbon! This is a great step for the sport, and is particularly poignant as the LTA transitions into its 1st full phase of its Environmental Sustainability Plan.

The new clubhouse is on the grounds of Frenchay Cricket Club. With the tennis club going from strength to strength, it became quickly apparent that the club required facilities of its own. DFTC appointed gcp to develop a project brief and designs for a tiny slither of land, located between the tennis courts and the site boundary. Given the site’s constraints, we focused on the core spaces required to support the club: a clubroom to host post-match teas, enable coaching briefings, and provide an all-important hub for club socials; a sheltered viewing area; and toilet and showering facilities. The 75sqm facility is designed to ensure accessibility for all with level thresholds throughout. Materials have been chosen to be robust, to ensure the club’s ongoing enjoyment of the facility without incurring high maintenance costs.

The club’s ambitions did not stop at a functional clubhouse. Clubchair Penny White and fellow committee members wanted an environmentally sustainable clubhouse, and we couldn’t be more pleased to support this ambition. We specified high performing thermal fabric and worked with an M&E consultant to ensure heating and ventilation systems would be as efficient as possible. We explored the option of Passivhaus certification. Unfortunately, the site constraints limited us to a long rectangular form running along a north-south axis, not ideal for Passivhaus. We modelled energy use and on-site energy generation and storage, ultimately achieving a design solution which is zero carbon in operation.

Construction itself has a high environmental impact. With the support of Structural Engineers at Build Collective, we looked at construction systems to minimise the carbon footprint of the building, whilst maintaining the high performance standards. An engineering joist system was chosen, along with wood-based insulation for walls and roof.

Having supported the Club in their funding applications to South Gloucestershire Council and Enovert, we are delighted that the project has secured substantial funding and look forward to being on site next year!

Planning Policy Across The Southwest

in , ,

2024/2025 will see wholesale changes to planning policy across the Southwest which will impact environmental strategies for all developments. But is the construction industry ready for these changes?

Bath and Northeast Somerset

Bath and Northeast Somerset threw down the gauntlet in Feb 2023 by introducing some of the most advanced low carbon planning policies in the country.

Policy SCR6 - Sustainable Construction Policy for New Build Residential Development

  • Space Heating <30kWh/m2/annum

  • Total Energy Demand <40kWh/m2/annum

  • On-Site Renewable Energy Generation to balance the Total Energy Usage

Policy SCR7 - Sustainable Construction Policy for New Build Non-Residential Buildings 

  • Net zero for regulated operational carbon emissions

Policy SCR8 - Embodied Carbon

  • Embodied carbon assessments required for developments over 50 dwellings or 5000m2. Score of 900kgCO2e/m2 for substructure, superstructure and finishes must be achieved.

BaNES’ local plan update also saw the introduction of a carbon offset fund for projects which could not achieve net-zero on-site. The price of offsets is anticipated to be £373-378/tCO2 based on the BEIS Green Book values.

The remaining members of the West of England Combined Authority are currently updating their local plans to align and surpass the targets set out by BaNES.

Bristol

Bristol have just published their local plan update which will be formally adopted in Q1 2025.

Policy NZC2 - Net zero carbon development – operational carbon

  • Space Heating <15-20kWh/m2/annum

  • Total Energy Demand <35kWh/m2/annum

  • On-Site Renewable Energy Generation to balance the Total Energy Usage

  • Passivhaus Classic offered as an alternative way to achieve compliance.

Policy NZC3 -Embodied carbon, materials and waste

  • Embodied carbon assessments required for developments over 10 dwellings or 1000m2.

Upfront embodied carbon:

o Residential (4 storeys or fewer) - <400 kgCO2 e/m²

o Residential (5 storeys or greater) - <500 kgCO2 e/m²

o Major non-residential schemes - <600 kgCO2 e/m²

Whole life-cycle embodied carbon:

o Residential (4 storeys or fewer) - <625 kgCO2 e/m²

o Residential (5 storeys or greater) - <800 kgCO2 e/m²

o Major non-residential schemes - <970 kgCO2 e/m²

Bristol local plan update will also include a carbon offset fund priced at the same rate as BaNES.

South Gloucestershire

South Gloucestershire are currently consulting on their new local plan which should be adopted in 2025.

Policy PSP6 – Onsite renewable and low carbon energy

  • Net-zero in operation. Regulated or regulated and unregulated TBC.

  • Passivhaus Classic offered as an alternative way to achieve compliance.

South Gloucestershire local plan update will also include a carbon offset fund priced at the same rate as BaNES.

North Somerset

North Somerset are still consulting on their new local plan, but the latest consultation document closely replicates that of Bristol.

Policy DP6 – Net Zero Construction

  • Space Heating <15kWh/m2/annum

  • Total Energy Demand <35kWh/m2/annum

  • On-Site Renewable Energy Generation to balance the Total Energy Usage

  • Passivhaus Plus offered as an alternative way to achieve compliance.

  • Embodied carbon emission targets currently being reviewed.

Interestingly, whilst Passivhaus Classic is being used as an alternative route to compliance by Bristol and South Glos, Passivhaus Classic does not actually achieve net-zero. This means quality assurance through proof of airtightness and no thermal bridging is being prioritised over renewables.

The direction of travel is clear, but how achievable are these targets. Analysis undertaken by the University of Bath reviewing planning submissions against the latest BaNES targets found the following:

  • 54% of eligible planning applications did not comply with the new operational energy policy, primarily due to a lack of awareness.

  • 1/3 of applicants submitted incomplete energy model calculations, making them unreproducible and difficult to verify.

  • 88% of those applications which failed to meet the energy standards were due to a lack of on-site renewable energy generation. Largely due to available roof space for PV.

Concerns were also raised around the cost of creating the necessary energy models to demonstrate compliance at planning stage. This applies particularly to small developments where these works will form a disproportionally large percentage of the overall construction cost.

Major developments will likely also incur additional costs due to the new offsetting requirements in BaNES and Bristol. Taking the RIBA Climate Challenge 2030 ‘business as usual’ model as a baseline the following offset costs could be assumed:

  • £94.50/m2 operational carbon (£7,465 for a 2-bed, £8,788 for a 3 bed) worst case scenario

  • £214.48/m2 embodied carbon (£16,943 for a 2-bed, £19,946 for a 3-bed)

These costs are significant and can add up quickly across a large development site. If you need any support reviewing your current or future developments against these standards feel free to get in touch for some advice.

gcp offer Passivhaus design, whole life carbon assessments, and energy strategy assessments which can help developers to navigate these new planning changes to make the most informed decisions.

Meet the Team: Matt T

in

Following on from Hazel’s Meet The Team interview, we have Matt Taylor, also celebrating one-year at gcp.

Matt is an Architectural Assistant who has worked for a variety of practices ranging from very small teams up to multi-office national practices. He joined gcp in 2022 to support our housing sector and is undertaking Part 3 training to register as an Architect.

Matt’s early employment enabled him to work on many small projects within sensitive areas such as Areas of Outstanding National Beauty, Sites of Special Scientific Interest and Conservation Areas, and buildings with listed status. Working later for multi-disciplinary and larger practices, Matt focused on developing masterplans for housing and mixed-use schemes ranging from 10 to over 1000 unit schemes, and progressing these through to planning.

Since joining gcp, Matt has been heavily involved in Retrofit, supporting contractors with on-site works for the fabric upgrade of social housing stock.

Matt’s experience lies most particularly within the housing sector. Through his extensive  masterplanning work he brings a thorough understanding of the opportunities and constraints linked to housing development, including the impact of planning policy and sites with special designations.

Having worked with multiple housebuilders and housing associations, he is able to very quickly provide appraisals for housing sites to suit each particular client’s needs.

Matt’s masterplanning experience is balanced with rigorous technical knowledge which enables him to provide technical coordination for volume housebuilding, and support  retrofit works in the housing sector. He has particularly been involved in pilot projects for the Social Housing Decarbonisation Fund and is working towards becoming a qualified UK Retrofit Designer to support projects delivered under PAS 2035.


Morning Matt! What we always like to ask first is, what inspired you to pursue architecture?

I had a big interest in the sciences as a teenager (mostly physics) but come from an artistic background, having two older artist siblings, architecture was what I saw to be a blending of the two interests growing up.

 

Great! And what has been your favourite project to work on at gcp, so far?

 

The SHDF wave 1 work (two Rivers) has been a high point for me as the first project ive taken all the way through from planning to completion, with the Help of Michael.

 

If you want to check our Michael Hanson’s Meet The Team: 23-year Anniversary Interview, click here.

 

This year has gone so quickly. What has been your best moment with gcp in the last year?

 

I can pin down any particular moment, but I’ve enjoyed the many social activities, Devon weekend, barbecue, even just the Friday pub, easily the most social office I’ve worked for.

 

gcp really pride ourselves on our social events and team activities, so really pleased you’ve enjoyed them. What do you like to do in your spare time?

 

I enjoy playing a lot of boardgames / DND, I also paint digitally in my spare time most days.

 

And what’s your proudest personal achievement? 

 

I once played paintball professionally (odd one I know its my dads doing) sponsored team and everything, got to play in France once .

 

Wow. So, if you weren’t an Architectural Assistant, what do you think you would be? 

 

Complete side-step but right up to when I decided on architecture I loved the idea of marine biology, so most likely that. Failing that some kind of artist.

 

Complete side-step indeed, but not surprising! You are a really interesting person with such varied hobbies. Lastly, I normally ask interviewees to tell us something we might not already know about you? 

 

I can play two instruments, bass and a bit of drums.

 

Another one for the gcp band! Thanks for your time today Matt, here’s to the next year.

 

Check out our blog to see more recent staff anniversaries, project news and round-ups of our recent social events.

 

 

gcp visit Edinburgh

in

It was back in 2020, when former director, Colin Powell moved to Edinburgh from Bath to fulfil a family dream of living in Scotland. A global pandemic, three years and many successful projects later a small group of the gcp team embarked on a mini-office-trip to pay him (and magnificent Edinburgh) a visit.

Our trip started early on Friday morning with a 7am flight from Bristol International Airport, landing us in Edinburgh just as the day was beginning to break. An atmospheric mist settled over the streets as we took the bus into the capital, finally splitting to cast glorious sunshine over the gothic city once brunch was over.

That first morning was for exploring – the Botanical Gardens, Modern Two, quaintly cobbled streets and an independent-makers-market inside a church were some of the sights taken in before we headed to our meeting place of Edinburgh Castle for a group experience.

We battled the crowds to take in the beauty of the sun soaked city from upon high. The breathless, panoramic views were worth being squeezed like sardines through the entrance and once inside the settlement it was peaceful with lots to look at.

There might have been a pint (or two) consumed afterwards in an quirky little pub and many thousands of steps clocked up on the step trackers.

Day Two started off with pastries and coffee (for those of us who didn’t have breakfasts at the hotel or AirBnB) and meeting Colin at the bottom of the Royal Mile, for a walk that started in a graveyard and ended in a café.

We took a meandering route, soaking up amazing views and the lovely streets of New Town. There were surprising pockets of nature to be discovered in the West End, all sprinkled with history, stories, anecdotes and interesting facts from Colin. We caught up as we walked, taking in what felt like an entirely different city to the day before.

Everywhere you turn in Edinburgh, there is something for your eyes to feast upon. Each street looks like it could be a scene in a film or the setting of a novel; I found myself saying “it’s beautiful, no this is beautiful” more times that I can count. With Autumn just at the edges of the trees and the weather zig-zagging between smokey skies and blinding sunshine, I felt like we really got the best it could offer.

After our tour we were armed with knowledge of the best bookshops in the city and filled with the most delicious toastie I’ve ever eaten it was time for a well-earned rest. Another 15,000 steps clocked in on the tracker, there were a few free hours (an amazing entrance-way in the National Portrait Gallery, yoga, a chapter of my book, a glass of wine) before we met again for a lovely dinner.

Colin surprised us all with some hand-thrown tea bowls (he has taken up pottery since moving to Edinburgh); and we finished the evening in a wine bar, chatting about our trip so far and sharing our go-to karaoke songs.

By Sunday, there was still more to do and by now, my fitness tracker was wondering if perhaps my watch had been stolen by someone who walks much more than I normally do. Today was Arthur’s Seat for some, bookshops, people watching and coffee for others. Signed-First-Editions, origami book pages, museums, galleries, parks, fountains, a fancy new shopping mall – we made the most of our last, long day, squeezing in as many of the sights as we could, before heading back to Edinburgh Airport for dinner and a late flight back to Bristol.

Sunny brickwork at Oakfield

in ,


A few weeks ago we jumped at the opportunity to take a few snaps of Nationwide Building Society’s Oakfield development in Swindon as the sun made a rare appearance. We spent some time appreciating the details which really make this scheme sing. The variety of brick detail, brick bonds, and brick specification gives each terrace a unique character whilst at the same time creating a strong identity for the 239 home development as a whole.


Part of our role as delivery stage architects is to facilitate efficient construction. We painstakingly set out each brick configuration to limit the number of cut bricks required and therefore minimise waste. Which makes seeing the fantastic results all the sweeter!

gcp Shortlisted for Novers Hill Design Competition

in ,

gcp are delighted to announce that we have been shortlisted in the Novers Hill Design Competition and will move forward to Stage 2 of the process. Below we share some of our process and considerations when appoaching a new scheme.

Background

Goram Homes, in partnership with the Bristol Housing Festival, launched a design competition on 2nd March 2023 for a new housing development in Knowle West.

Situated just off Novers Hill, the brownfield site bounds the ecologically significant Western Slopes, with fantastic views over Southwest Bristol.

Having previously worked with Goram Homes to report on and reduce their whole life carbon emissions, we jumped at the chance to produce a sensitive, low carbon exemplar design for the Knowle West community.

Our Process

Context is always important, but especially on such an ecologically significant site. Our process started by analysing the site from an ecological, social, geographical and historical point of view.

This allowed us to identify the areas which could be developed whilst limiting any negative impacts on existing habitats. The brownfield elements of this site offered an obvious development opportunity due to the level topography and lack of ecology.

Taking the developable area, we could carve out service routes and ancillary spaces, leaving the most suitable areas for the proposed dwellings.

Working with a concept massing allows many ideas to be tested at a site-wide level to investigate their suitability. We took this opportunity to adapt the form to better make use of the site’s natural resources such as sunlight and views.

Retaining a connection between Knowle West and the Western Slopes was a key part of integrating this development into the existing community. To encourage this, we chose to slice through the massing to form a physical link between the wonderful green spaces and the wider community.

Creative stacking of gardens allowed us to achieve the required housing densities without damaging any further green space. This stacking also made the most of natural daylighting and views.

Our Team

We selected a competition team with a wide ranging but complimentary skillset to efficiently deliver this competition entry.

  • Part 2 Architectural Assistant: Matt Taylor

 

The core team of Matt B, Matt T and Owen developed our design under the excellent stewardship of Sarah. Regular concept discussions between the core team allowed for speedy testing and evolution of ideas. Concepts were then presented to the wider office during several design reviews in our pin-up space, which helped to hone the proposal and focus the mind.

Holistic Design

We pride ourselves on being able to take projects from the first sketch all the way through to delivery. Part of this is thinking ahead and making sure we consider the detail within the big picture. Whilst this was a Stage 1 design, we wanted to ensure that buildability, sustainability and affordability were all considered to ensure smoother development as the design progresses. It is much easier to design in efficiency at an early stage than try to adjust a poor design further down the line.

In developing our submission, we considered:

  • Whole life carbon emissions by improving thermal performance, choosing low carbon materials and maximizing solar gains

  • Materials to allow for ease of construction, minimal ecological disruption and easy airtightness

  • Going beyond biodiversity net gain by retaining as many habitats as possible, enhancing existing grasslands and planting trees/vegetation to offset carbon emissions

  • Net Zero emissions in operation through an efficient form, fabric first design and large solar PV arrays

  • Affordability by eliminating unnecessary junctions/details, minimizing energy/running costs and reducing the overall building mass.

The Submission

Detailed site analysis and holistic design allowed us to generate an accurate impression of how the development could look.

Planning Submitted for Aerospace Engineering Company

in ,

gcp have recently submitted for planning consent a scheme to extend and reimagine the McBraida factory building at Bridgeyate near Bristol. McBraida plc have operated at this plant supplying precision machined parts to a domestic and an increasingly important international aviation market.

Over the last 30 years, as the business expanded, the original brick factory unit has been expanded in piecemeal fashion without any fundamental re-planning of the production space, or strategic view to the future. Consequently, the site is now operating at significantly below optimum efficiency due to the resulting cramped conditions. Likewise, the industry shift into computer aided design and manufacture requires an expansion in office area to accommodate these increasingly desk based manufacturing processes.

Driven by overseas sales success and the lack of space at the Bridgeyate plant, in 2013 the business opened a second production base in Poland. This is a purpose-built modern factory unit with an efficient layout and high levels of staff satisfaction with the workspace environment. It is equipped with all facilities expected of a modern engineering production plant including offices, laboratories, testing facilities, meeting rooms and a client presentation suite. There is a stark contrast between the highly efficient McBraida Polska plant and the somewhat dated, inefficient, sub-optimal accommodation at Bridgeyate.

The proposed extensions will envelope most of the existing factory and will give increased production area, storage, new offices and staff facilities to a high modern standard. The public image of the McBraida works will be transformed from its current anonymous appearance. The intended design aesthetic is ‘modern industrial’; appropriate for the company’s business although to a higher specification than a standard industrial unit. The public-facing façade of the building will express the forward-looking aspirations fitting for this high technology company.

5 new homes approved in St Werburghs

in , , ,

gcp has recently secured planning approval to convert a Victorian warehouse on a landlocked site into 5 new family homes.

 

In a bid to not only consider the building’s history, but embodied carbon as well, the original red brick building has been retained. The 2 later concrete extensions which were in a state of disrepair will be demolished, with one of them being rebuilt in a similar sized footprint and the other becoming garden space for the houses.

 

The red brick building boasts tall ceilings, timber sash windows and an open plan design. The scheme will have PV, water butts and air source heat pumps along with planting boxes to help drainage and encourage new ecology on what was previously a concrete wasteland.

 

The new extension is built with the same red brick as the existing on ground floor to tie the buildings together but has a striking black metal cladding on first floor to pay tribute to the industrial nature of the original site and much of its surrounding areas. To ensure the scheme does not impact surrounding homes, first floor rooms are in the roof, but with high eaves to ensure high quality and useability of the space is achieved.

 

We worked closely with the Bristol Planning Department to ensure a positive outcome was achieved – a design sensitive to its surrounding neighbours and energy-conscious in both embodied and fuel, providing high quality living for future home owners, and maintaining its history from Olliff’s Antiques Warehouse. Upon redevelopment, Olliff’s Architectural Antiques will relocate to an alternative location elsewhere in the city.

 

This scheme follows on from the highly successful Brooks Dye Works project we delivered for Acorn.

End of Year Wrap Up: 2022

in , , , , , , , ,

2022 has seen the “new normal” become the normal-normal, with hybrid working and remote meetings just a part of everyday life now. With bubble-working and office closures a thing of the past, the word of the year at gcp has been collaboration. We have really enjoyed being back in the office together, sharing stories and cakes at our Monday huddles and using our new whiteboard space for design workshops.

We started the year by offsetting carbon emissions: a frosty January day was spent planting trees with Avon Needs Trees. gcp are committed to tackling climate change both through our designs and our actions. We hope to build off this initial planting session by further developing our carbon tracking, reduction, reporting, and offsetting strategies to better understand how we can make a difference.

In February we celebrated national apprenticeship week, with architectural apprentice Owen Faunt. We are pleased to be supporting Owen through his Architectural Apprenticeship at South Bank University, London. We love discussing his projects and seeing his finished work and are incredibly proud of how far he’s come since his change of careers 3 years ago.

Part of his experience this year was the chance to work on The Ranch, Southmead, with DIY SOS. gcp helped with the overarching vision and Owen got the chance to put his amazing sketching skills to work.

Team challenges form the cornerstone of office morale here at gcp, and in March we split into team-bikes and team-books to see who could go the furthest – readers or cyclists. Team reading easily beat the cyclists, though with their many pub lunch cycles clocked up, who was the real winning team?!

In July, some of the staff, their partners and families took a relaxing weekend trip to Devon and in September we celebrated the company’s 30th birthday with our favorite memories and a huge cake.

2022 has seen a boom in recent sports project experience. gcp were proud to help bring a top class sporting facility to West London, with the completion of a fantastic cricket centre developed in conjunction with the Wilf Slack Trust, Middlesex Cricket and Willam Perkins School. We have some more exciting sports projects on the program for 2023!

Our long-running relationship with Curo continued this year, with Century Park a 128 unit scheme progressing well on site. This scheme has received great press and is a finalist in Bristol Property Awards, for Residential Development.

Alongside marking a continued relationship with Curo, we were pleased to be working with EG Carters, a partnership which has been ongoing for over 18 years. We have worked closely with the EG Carter team over the years to find practical development solutions for often tricky sites across the South West.

Our first project together (back in 2004!) was a small infill housing project in a dense urban neighbourhood in Bristol. Current projects include Rural Exception sites in Somerset and Wiltshire where we have worked closely with the E G Carter team, jointly negotiating our way through complex planning, land and environmental issues, to deliver needed affordable homes that are welcomed by the local community.

We celebrated with Acorn Property Group and Halsall the completion of Brooks Dye Works, a 113-home regeneration project in St Werburghs, Bristol.

Our initial contact with Acorn began when we supported Halsall Construction on the Otters Holt development in Ottery St Mary, a complex brownfield development in a conservation area. Acorn subsequently approached us to resolve planning conditions and provide technical design for their major project at the old Brooks Laundry in Bristol. Alongside architectural design we also provided energy assessments to meet Acorn's performance targets through our in-house energy consultancy.

Alongside our continued housing experience and exciting sports projects, we have been working on Retrofit in the Forest of Dean. At the CIH conference in September, Tom Mellor presented alongside Curtins, Two Rivers and Rider Levett Bucknall as part of the “Bristol Retrofit Collective” speaking to Demystify PAS2035. We will be running some further seminars on this subject in the New Year, so please get in touch if you’d like to get added to the list.

All in all, it’s been a busy year for gcp and we rounded it off with a lovely Christmas meal in Bristol last week. After a busy few months, it was lovely to gather around the table, enjoy good food and even better company and raise a glass to the success of our small team over the year.

We can’t wait to see what is in store for us and for you, in 2023.

Season’s greetings to all and wishing you a very happy New Year.

Brooks Dye Works complete! Regeneration at the heart of St Werburghs. Bristol.

in ,

Brooks Dye Works sits within the dense Victorian terraced streets of St Werburghs in central Bristol. With an industrial use dating back to the 19th century and its distinctive 39m high brick chimney providing an important landmark for the surrounding area, the site is a key regeneration project in this part of the city. Acorn achieved planning approval for a development of 89 homes, new highways and public open space in 2017 and needed to deliver a complex project with challenging technical requirements. Our previous work with Acorn and our knowledge of this area of the city (illustrated by our completed projects closely adjacent to the site) gave Acorn the confidence to appoint gcp as their Architect for the following stages of the project. Brooks Dye Works has been a major part of our office life for the subsequent 5 years, as we worked closely with Acorn’s design team and Halsall Construction, the contractor delivering the site works at Brooks.

Acorn have high production values and a clear concept for their product, wanting to provide high quality contemporary homes that are attractive, flexible and efficient. These are values very much shared by gcp, and our pragmatic approach, backed up with excellent design and technical knowledge, supported the delivery of this project on multiple levels. Our principal responsibility was in optimising the design and developing the construction solutions to deliver the product Acorn envisaged. In addition, we managed the complex planning implications and discharges required by the planning approval. Our consulting team managed the energy assessment and certification of performance to ensure delivery of new homes that are energy efficient and incorporate renewable energy systems to reduce carbon emissions.

For our team, the project has strong personal connections also – anything you work on continuously for 5 years leaves a mark!

Siobhán Tarr, our Senior Technologist, has led the technical design from inception to completion, applying her knowledge and rigour to all aspects of the design. She says;

“Having grown up in Bristol I am always interested in my city and how the regeneration of different areas enhances my hometown. I have friends who live in St Werburghs and have spent many hours exploring the surrounding streets, so it was great to play a part in the regeneration of this area. I’m looking forward to exploring some higher vantage points to get a different view of the scheme and really see it nestled within the streets I already know. The chimney is a feature I love, it’s fun moving around the area and aligning it with different views of the streets and the new homes. I am so pleased to see residents moving in and making the place their own with the individuality that is so characteristic of the area.”

Colin Powell, Energy Architect at gcp, has managed the planning approvals and consents throughout the project. He says;

“We have always built our business around relationships with people and I was so pleased to work with Acorn again on this project. As a client they take a close interest in every aspect of a project, bringing a clear focus on design quality and practical solutions that I like to think is an area we excel in. I think this is possibly one of the most complex planning approvals I have managed, and keeping track of the different consents, new applications, conditions and discharges has been quite a logistical challenge. The completed project is a credit to everyone involved and as the development matures it will fit seamlessly into the surrounding community and the dense urban character of this part of the city.”

And our joint favourite moment;

“The Brooks ducks and ducklings, who waddled through the construction works on a regular basis, oblivious to the construction activities, making their way to the new Pond in Mina Park. Hopefully the residents will get to enjoy a new duckling family every year.”
