1960s house renovation (inc ASHP), and extension

[HandyAndy]

Hi - we are renovating a 1960s house in St Andrews, taking over the family home from my father who liked it just the way it was (including original kitchen and bathrooms (complete with mint green suites!)). He was into renewable energy, so we benefit from PV electric and thermal solar, and he had replaced the original Crittall windows with double glazing.

 

We've made some progress so far, including self-replacing end-of life/ draughty UPVC with highly efficient triple glazing (it was fun lifting 90kg windows to the first floor!). I'll also share the mixed experience of having an air source heat pump installed. Currently adding copious insulation into the large, uninsulated vaulted hall and finding a satisfying 3'C temperature rise as a result.

 

Next piece in the jigsaw is to have an extension built, and finding that builders are like the proverbial hens teeth ...

 

I've appreciated lurking on this site for ages and being able to draw on people's thoughts ...
