We are four couples building in Dunblane, Central Scotland.
With a keen interest in sustainability, our aim was to build to Passivhaus standards.
The cost of the build has unfortunately made this impossible. However, we are really, really close to it.
Air tightness
Scottish Building Standards state that
It is recommended that buildings be designed to 10 m3/m2.h @ 50 Pa or better though an infiltration rate of 7 m3/m2.h @ 50 Pa is used for the TER calculation.
We are expecting our air-tightness tests to achieve a rating of around 1 m3/m2.h.
Architect
Our architect is Chris Morgan of Locate Architects.
Passivhaus Dunblane 
Hi there, I have been trying to find information on your builds for a while now and wondered if you could forward any details of the properties and if any plots are still available? Many thanks in advance
Sorry, Ruth, none of the houses are for sale. We’ve all built them to live in.
(And sorry it’s taken so long to reply. I’ve just seen that your comment had been caught up in the anti-spam mechanism.)
Hi there,
We were planning to do the same on our build in France, but the costs are prohibitive, It is a much about getting the term ‘passivhaus’ attached to your build that costs! You can still be a passivhaus in principle but without the test to prove it, you can’t call yourself that! So it is everything that a passivhaus should be just not in name!
Good luck with the builds – it looks very exciting.
