Floor plan design single-family house approx. 230 sqm plus basement

Are children's rooms of 16sqm exaggerated?

With 230sqm of living space, children's rooms of 16sqm are understated.... GD

Thank you for the very helpful contribution.

Yes. You will throw out a number without exactly describing how you arrived at it. Please explain how you got to this value?

Good that you ask. First of all, experience shows that houses of this size are not equipped with cheap/low-cost fittings. That’s a start.

Current construction costs (no, not Town & Country, but classic with an architect or similar) are €3,000 per sqm of living space, plus X.
That’s already the first €690k.
Then there is a basement, for a fully basement-used area as a utility basement about €1,000 per sqm. If it’s within the thermal envelope or finished, then even more.
Assuming that it’s not built "cheaply," I simply add €50k on top of the house (then €3,200 per sqm). And I have calculated a buffer of another €50k.
Earthworks, architect, double garage, etc. are still added on top.

P.S. These are empirical values from my job

Only just under 2 meters for the wardrobe plus a chest of drawers in the parents' bedroom? That's not even enough for me alone.

Thank you for the very helpful post.

Ok, I wanted to "provoke" a little. But essentially, you are planning a pretty large house for "normal" conditions and a "normal" budget. And with this actually great possibility to create "generous" spaces, you plan a floor plan in which the proportions are completely "off" in many places. Example? Kitchen 23 sqm is huge, compared to that a bathroom with 7 sqm is small (but doable). And a children's room of 14 sqm as well. Next to it a children's room of 18 sqm, which I find generous, but appropriate given the overall size of the house. Then there is a bedroom with 20 (nice!) into which basically no usable wardrobe fits. And a workspace of 9 which is also modest. And basically everyone here is saying nothing else than that the plan needs to be completely redone - BUT FIRST you have to know the financially feasible total area. They are not trying to cheat you with the budget but every good architect will ask you this question right at the beginning. GD

If you do not respond appropriately to post #9, I'm out of here.

House and property should be considered together.
