You have a floor area of almost 230 m², but the children's rooms, for example, are "tiny" for that. The dressing room isn't exactly huge either, and the master bedroom is bigger than the children's rooms even though it is probably only used for sleeping.
If I compare that with our floor plan: living/dining/kitchen is 8 m² larger in your case and the bathroom is bigger. Otherwise, you don't have more usable space on 113 m² than we do on 89 m². That's where I would start.
If we quickly add the basement again, then we are at 340 m² floor area. According to your calculation, it won’t be long after moving in until the older child moves out. I would really question this order of magnitude.
To be honest, I don’t understand your calculations. What is the meaningfulness of a calculated-up floor area except for a cubature? Even counting the basement, which has no relevance for living? I understand what you’re getting at. But your calculation only pretends a pseudo-objectivity that comes solely from the corridor area.
If I now subtract the 8 m² and the bathroom from the 113 m², how much difference remains?
If you have an idea how I can reduce the corridor, I would be very happy to hear it! I am now at floor plan drawing 15+ and have not found a variant in which a reduction of the corridor area sensibly results in usable rooms.
Other city villas use the larger corridor for access to the rear rooms with a straight internal staircase – here the staircase pushes everything 2.50 meters upwards on the plan, so there is no longer enough space for the high number of rooms. In addition, there are the ancillary rooms upstairs, which also require width.
Yes, that is correct. However, a straight staircase does not work because of the basement access. I have also planned a reduction of the entrance area. Then the corridors will be smaller, but the extra space brings no added value to the relevant rooms. And relocating the rooms always resulted in the "nice" window sides being occupied by unimportant rooms such as the dressing room, or the two children's rooms becoming significantly unequal.
Perhaps one of you could sketch an alternative room layout, then I will try to work something out from it. Unfortunately, I am running out of ideas. Criticism is welcome, as it stimulates personal thinking. Ultimately, possible solutions are just as important. Although I have to say openly, real compromises are hardly included from our point of view anymore, especially none that we cannot live with. Otherwise, I wouldn't have posted the plan.
I can hardly imagine you getting by with 400,000 for a house of this size
The house has already been calculated including surcharges and including ancillary construction costs; there is still a buffer (without garage, without landscaping). Basement with white tank, air-to-water heat pump, controlled residential ventilation.
