About Us


Our history

Passivhaus Homes has been formed from two companies, Williams and Partners and Cotterell Thomas and Thomas (CTT). Together they have more than 40 years' experience working in the built environment. Both have established reputations working on conservation projects in sensitive settings, where a careful, intelligent approach, paying great attention to detail and high quality craftsmanship are all essential.

Our philosophy

We strongly believe that adoption of Passivhaus methodology and the Passivhaus standard are key to responding practically and effectively to some of the many social, economic and ecological issues that face us in the early 21st century.

The Passivhaus focus on co-operative, careful and intelligent work by a properly motivated and appropriately skilled team appeals to us greatly, with the emphasis being on "getting the fabric right ". And in order to achieve this the right materials and services need to be available, easily and economically.

Why Passivhaus Store?

Because of the difficulties we had sourcing materials with our own projects, we set up www.phstore.co.uk to supply products we found made achieving the Passivhaus Standard easier. Whether you are aiming for Passivhaus, EnerPHit, zero carbon (Code for Sustainable Homes L5 or L6) or AECB Silver, we believe Passivhaus Store will help you achieve your ultra-low energy build as cost-effectively as possible.

The future

We are constantly researching new products and will continue to add those we feel make a real contribution to future Passivhaus and other ultra-low energy builds.
