Hello everyone,

For several months now, we have proudly owned a plot with an existing building and plan to start construction next year.
After several rounds with architects and general contractors (GCs), two are still in the running, and we want to decide by next month at the latest who we will build with.
The design mostly incorporates my sketches, and the more serious it gets, the more uncertain I feel about how coherent the planning is.

I have been following the forum for some time and look forward to your honest feedback, hoping not to be torn apart too harshly in the "lion’s den."

P.S. The site plan is not 100% accurate since we slightly enlarged the ground floor in the last round.

Do you still see potential for optimization on the ground floor?
I would rather call it a “need”: the wind tunnel between the garage and the house will bring you a lot of discomfort.
How exactly is the staircase supposed to look if the treads are wood and the risers are white, but it should have a folded structure appearance? – The only “folded structure” I know involves treads that meet the risers without overhang. How do you plan to achieve a color change “mitred” like that?

This is phrased somewhat awkwardly. We requested an offer for the staircase entirely in wood with a folding structure design, or alternatively with oak treads that extend slightly and risers painted white. We decided against the folding structure design.

How could the "requirement" be optimized? Would a shorter roof help to ease the situation? I find it a bit difficult to assess.
