Single-family house cube without roof with full floor

Does the terrace count towards the floor area ratio? I already quite like the first draft. The openness is a bit too much for me. The guest toilet is not really a retreat because of that. The clearance spaces in the kitchen are too tight. In this case, fewer pieces of furniture might be more. The sketches should be completely sufficient as a conceptual draft for the architect. It's more important to write down the list of requirements and wishes. It’s best to have the architect proceed without a sketch at first.

I would reconsider the kitchen. Not a reduction of the kitchen unit, but away from the [Showküche]. The house is too small for the kitchen

Different stairs.
Straight stairs and the [Showküche] are space eaters.

Wall thickness 32? Here, it is certainly planned with 17.5 bricks in connection with 14 cm mineral wool.

Sporty are 82 and 78... how do you get 31.5 wall thickness?

The outer wall without insulation should be that thick, right? I only meant the walls. No idea about the insulation but that’s on the outside anyway.

With the requirements (flat roof, garage), I think the folding staircase is the smallest problem in combination with the budget

The wall thicknesses don't fit. Where should storage space for 4 people come from here? Washing machine in the utility room downstairs?

Yes, the washing machine goes there. But hey, we are from Berlin and the stair builders come from Poland, which saves quite a lot of costs. How expensive it will be in the end the architect has to calculate. There are 2 children's rooms with 15m2. And for storage, besides the utility room, there is the garage.

Do you also want to build in Berlin?
