Hi there all, due to the death of my dear Dad we needed to support Mum, and so built her a wood passive-principles place in 2016. I oversaw the build.
The main chalet bungalow (that I grew up in) is where we've been living for 2 years, alongside Mum in the garden. Its proved too poor in construction to remedy it, so that decision has been to rebuild. 3 years in the preparation, we're hoping to demolish in April.
We're looking at an economical build using Heluz blocks to ensure a passive- build. The economy of these will hopefully offset the huge cost of excavating and piling the sloping site to enable us to add a lower ground level, turning it to a house without looking different in the road. The pre-app has gone through smoothly, now to face the reality of living in a trailer tent, and funding the project.
Specifically I'm looking at Kingspan Standing Seam roof and MVHR unit again.
Looking forward to reading all your plans and thoughts!
Chantal
