Waxham, Norfolk

Project Outline

Project description: The family home is being built to Passivhaus Standards using the Beattie Passive Offsite delivery method. The 130m2 single storey 4-bedroom home is based in a secluded seaside location off a private track in idyllic Norfolk countryside.

Client: Simon Fenn & Mitra Cvijanovic

Client Verdict: “We find the most interesting element is to see the gulf between a traditional build and what is a more modern approach. Now it almost seems quaint that you would want to build a ’traditional' house with bricks and mortar, especially knowing that the end result is going to be way behind a Passivhaus in terms of running costs but more importantly in terms of comfort. The Beattie Passive approach, with the emphasis on air tightness, super insulation and the elimination of thermal bridges, is really the way forward.”

Technical Specification:

Wall U value: 0.11 W/m2k

Roof U value: 0.11 W/m2k

Floor U value: 0.09 W/m2k

Air Tightness: <0.52 hm2@50Pa

"Working with our client on his third project and being at the forefront of energy efficient design, it was a natural progression to look at Passivhaus as a way to deliver a high performing and quality build for our client. We approached Beattie Passive to discuss the design and it began with them supplying just the design, technical and testing package, yet subsequently grew to the provision of a complete watertight building!

We have been very impressed with the high quality of construction and the delivered house exceeded our expectations on Passivhaus standards. It has been a pleasure to work with the team at Beattie Passive as they are willing to share information and their developed 3D models which work easily in conjunction with our designs. Overall it’s been a great experience in Passivhaus projects and one we look forward to repeating in the near future."
