The Trees, Frome

Client: JCDC Developments

We provided design services to JCDC Developments to help establish the thermal performance of the property along with assisted input on appropriate MEP systems to ensure future efficiency and low-cost bills. Complexities arose regarding the two circular towers, trying to ensure consistency of insulation through curved walls in a complex timber frame structure provided its challenges. These issues were overcome during the design phase with the client and we subsequently provided Design and As Built SAP Assessments, EPC Lodgement, U-Value Calculations, Part G Water Calculations and Condensation Risk Analysis. Our client is pleased with the services that we provided on this project, and made the following comment:

‚ÄėThere are always so many options when it comes to specifying materials that it‚Äôs nice to pin down the best alternatives with people that understand the construction methods.‚Äô

Corten Courtyard House, Bristol

© Greg Pittam
Client: Barefoot Architects
Awards: RIBA South West Award 2021, RIBA Small Project of the Year 2021, RIBA Project Architect of the Year 2021.

We were appointed to this project, Courtyard dwelling in St Werburghs, Bristol, on behalf of our client Barefoot Architects, to provide an Energy and Sustainability Statement to meet Bristol City Council’s Planning Policies.

The house is timber frame construction, clad in Corten rusting steel, which rises up above the brick boundary wall and descends down into the courtyard, its purity contrasting with the rough, graffiti-strewn fletton bricks below.

This project featured in the Architects Journal, who completed a Building Study on the completed project which consisted of a contemporary, cor-ten clad, highly insulated timber frame home inserted within an existing brick boundary wall.

‚ÄúThe success of this project is testament to a client and architect working in harmony. Some unusual decisions have been made, chief among them being to keep the existing wall and to celebrate it. Built to a limited budget, the house is exemplary in doing a lot with a little, and in turning constraints into opportunities. It provides a home perfectly suited to its client‚Äôs needs, and has transformed an unloved urban corner into a talking point and landmark for the local neighbourhood.‚Ä̬†¬†‚Äď RIBA Judges
