We are experienced in new build and refurbishments in both the domestic and non-domestic sectors.

Building physics and thermal dynamics drive our philosophy and we approach our projects ‘Fabric First’ to deliver buildings that are comfortable, simple and efficient.  We work on new-build and existing buildings optimising insulation, fenestration and thermal bridging to produce robust buildings with minimal systems necessary to maintain comfort.

Fabric first

Passionate about sustainability

We are passionate about delivering sustainable buildings that satisfy the occupants’ comfort, with the controls most appropriate for them. We are completely independent of manufacturers, products and installers so can provide objective advice, backed up by a suite of software tools and research. By optimising the insulation and fenestration, and designing for maximum air tightness and minimum thermal bridging, we aim to produce a shell into which simple, robust, minimal systems are added to ensure comfortable conditions can be maintained.

We have a wealth of experience in designing the M&E for new and old buildings in particular relation to low energy buildings. We offer a wide range of services and can adapt our scope to the necessary level of detail required.
