We are an award winning team of engineers, architects and building professionals who are passionate about the health of both our built environment and our planet.

The UK’s buildings are responsible for over 20% of the UK’s carbon emissions and thus producing low-energy buildings must be a key priority if we, as a nation, are serious about taking action to improve energy security and meeting our carbon emission targets.

We’ve designed passivhaus retrofits (the first two in the UK), passivhaus new-builds, developed programmes for retrofitting social housing property and saving energy in hair salons and helped over 300 clients build or renovate warmer and more comfortable homes.
