On Thursday we had a site visit with an architect at the property.
He also found the location and lighting very good since the forest is to the north. Access through the narrow dead-end road to the east is also favorable. In terms of budget, based on his experience, we should expect about €310 per m3 of built volume. A basement would be necessary/sensible due to the slope.
He initially assumed a 1.5-story building + (residential) basement (e.g. with separate floors for parents/children) but considered this rather unrealistic within our budget (I agree). He also considered our proposal (essentially a bungalow with a residential basement, bedrooms below, floor plan etc. I did not show him) possible, but as I got the impression, he was not so enthusiastic about it and would have preferred to get us to agree to a higher budget.
He also mentioned a split-level construction method, which, however, does not appeal to us. Regarding exemption from the ridge orientation, he was quite confident and recommended speaking in advance with the person responsible at the building authority.
We are unsure whether he is the right partner, as I had the impression that building with our budget does not quite suit him. We will now first carry out the property purchase and simultaneously contact other architects/providers.
Maybe you could take another look at our draft (please excuse the missing staircase on the ground floor, I just noticed, of course the position is as in the basement or the older plans)?
