Uh, he wants 325,000€ for just over 100m² of living space plus a basement? Unless there are some massively golden faucets hidden somewhere, that is definitely too expensive.
If I convert my total floor area/living space ratio to your living space, then you have something around 105 sqm on the 2 full floors and your finished attic + basement.
So it could be about right:
- 105 sqm x €2000 = €210,000
- Basement €50,000
- Finished attic: unfortunately no idea how much to count there.
Where are you building? I always calculate about 1600 euros per square meter of living space with the Energy Saving Ordinance. If that applies in your area, that makes 224k + maybe 40k for the basement. In that respect, it would be too expensive for me as well.
So it could be roughly right: - 105 sqm x 2000€ = 210,000 - Basement 50,000€ - finished attic: unfortunately no idea how much can be credited there.
The eligible costs are based on the net amounts (the 2000€ per sqm are gross) for the building construction with technical equipment. No house connections, sewage shafts, etc. Where the 325K€ could come from is quite questionable. But nothing is certain.
we are planning a house with
external dimensions of about 7x8 m
2 full floors
roof 45 degrees without knee wall; converted
with basement
I don’t see that working. The footprint is extremely small and therefore uneconomical (proportion of walls and stairs to the footprint is disproportionately high), I also see roughly about 110 sqm being feasible there. Two full floors plus a 45° roof already greatly restrict the choice of plots where this is allowed – these will also rather be those where only semi-detached or terraced houses are permitted. The latter would typically also have about 20 sqm more footprint, so somewhere between, for example, 7 x 11 or 7.5 x 10 m.
A house built relatively like a "tower" is actually typically expensive in relation to the enclosed space. I read from this a considerable amount of naivety regarding the parameters that are supposedly suitable to make a house feasible on a small budget; and I am therefore almost certain that there is not yet a concrete plot for these considerations.
