Evaluation floor plan approx. 145 sqm single-family house basement/ground floor/upper floor

The question I have asked myself quite often: Is the cost advantage really that big if I park living space in the basement and, in return, plant a garage (yes, then also with additional slope protection) next to the house? Hard to imagine for me as a layman, but as I said, as a layman ;-)

The first cost estimate from the architect was at the end of last year at 440k (without own contributions, including all ancillary building costs, only for the house). At that time, however, we still had a more complicated floor plan and 160 sqm living space / 220 sqm total area.

Provided it would dramatically reduce construction costs, one might also consider doing without the office in the basement.

Counter question: do you believe that by using the UG less for living purposes – that is, by only occupying potential living space with parking cars, etc., and thus getting by with storage room standards there – you can compensate for the living area needed for the rest of the living space above?

Show it for fun, maybe there were elements worth adopting.

Overall, I get the impression that you rushed through service phases 1 and 2 rather sloppily. Show the drawings from the preliminary design phase once.

how certain is it that the west side will also remain free in the future? Or is there a threat of further development in the next few years?

Why I ask: if the west remains free, you can build parallel to the slope (ridge direction north <> south) and orient the living/cooking/dining area to the west, rather tube-shaped in the basement (= cellar). On the ground floor, then bedrooms and children's rooms. If planned cleverly, you would have direct outdoor access on both floors. The attic can simply be converted for home office, guest, storage room, etc. The whole thing in an elongated cubature and you have endless light and views!

I would definitely ban the parking spaces from the house and place them directly on the street where it makes sense (a cleverly positioned carport brings additional privacy, can help with land modeling, and fits well into the landscape from above with a green roof :) ).

Google "House for Björn and Julia" and just imagine the car/garage part on the left side of the plan gone. That shows quite well what I mean (even though the project itself is probably out of the price range).

Also worth seeing is the project "Glückauf Vier" by "K2 Architects". The living/cooking/dining is upstairs, but the house is somewhat rotated towards the slope and very well integrated. Also access on both levels.
