So, I'm renovating a house (part of a barn) in the Alps. It is a shell at the moment, so we have pretty much total carte-blanche on what we do with it.
The plan is to have 3 bedrooms + bathroom downstairs, upstairs open-plan kitchen, living area, dining area (+ eventually mezzanine).
There are just 2 of us at the moment, so 1 bedroom will be a spare, the other will be an office for now until we get the mezzanine built some time down the line.
Need to decide soon what we're going to do for heating. Wood burner upstairs is a given. Do we need additional heating beyond that?
Downstairs, underfloor of some description. Wet? Electric?
Insulating to the max is a given
No mains gas
Fair bit of land outside, so GSHP is possible, but ground is steep, rocky & cold, so likely to be expensive.
Budget is tight, so, unfortunately, initial cost is a very big factor.
It's in the valley floor so gets COLD on clear, calm nights in winter.
