“We are delighted with our new house. Green Building Store and the building team have worked with us to create the style of house we wanted, whilst also meeting the exacting requirements of the Passivhaus standard. We have been delighted both with the design and the quality of the build. It is light, airy and spacious while also using 90% less energy for space heating than standard. We have enjoyed the inclusive process of being part of the building team and have been fully involved all the way from our initial discussions in all the stages of the design.”

Geoff & Kate Tunstall – owners of the Denby Dale Passivhaus

“Bill and Jude and the rest of the wonderful Green Building Company team took on a 250-year-old barn conversion for us and though constrained by listed building criteria managed to create a home that uses just a fraction of the energy of our previous dwelling. Most of the gains are down to good airtightness and to high standards of insulation – and all without detracting from the original ‘character’ of the historic building”.

John & Cate Clark – West Yorkshire

“The Green Building Store team is to be commended for adapting the Passivhaus methodology to British building techniques and for constructing the first Passivhaus using cavity wall construction in Britain. The Denby Dale project has proven that Passivhaus design can be easily adapted to British building techniques. Airtightness is not a myth – the rules of physics are the same everywhere – and wet plaster offers an excellent airtightness barrier for cavity walls, if applied to all surfaces of external walls and connected properly at the joints. The Green Building Store team has done a great job at Denby Dale and also in helping to spread the word about Passivhaus design in the UK. Congratulations!”

Professor Wolfgang Feist – originator of the Passivhaus methodology and founder of the Passivhaus Institut in Germany

“Green Building Company’s workmanship has always been excellent and we have also really valued the company’s proactive approach. Bill, Jude and the team always try to actively solve problems and improve detailing – something that has not been my experience with other builders.”

William Young – West Yorkshire
