Services we offer
We help and support clients designing and building a low energy, sustainable home, or retrofitting an existing one, using Passive House principles: from early pre-planning through to on site technical advice towards Passive House or another certification.
Use as much or as little as you need
We recognise that clients come with differing experience of the design and build process and are likely to need varying levels of support, so you choose the services that suit your project.
