15 days to install hahahahahha, Did our first and second fix in less time than that including fitting the bathrooms.
I think they are taking the pi$$ out of you.
be interesting to see if a combination of trickle vents and one of the single room type MVHR units, this one does 50m2, would be a comprimise on heat recovery vs full mvhr

core directly behind the ASHP and you wont see the connection. Make the hole big enough so the insulation is not compressed and then seal it up real good.
klober do a really nice dry virge, gives a much higher end look than a sea of plastic fascia and barge

non-habitable rooms should not get damp enough to worry about as its us that generate most of the moisture. Insulation job is to prevent condensation by moving the dew point inside the insulation where condensation cant form.
interesting.
But how are rooms without a dmev unit in, bedrooms, studies, living rooms etc supplied with fresh air ?
Really needs to be a low cost midpoint between full blown MVHR and through the wall fans with trickle vents.
2 issues jump out, highways and a new access on the bend. space for at least 1 car (if its a 1 bed) to turn around in.
The rear will be overlooking neighbours amenity space.
