Opinion on the house design

... have you read ? Maybe you should explain why it has to be Kfw 40. And, as I said, whether the office is attached on the side is not the crucial question in your design at all, because your design DOESN'T WORK AT ALL. I mentioned the most important points in . Therefore, the architect's design would be interesting, you could then check it against the things you don't like about it.

the drafts from the architect

I want to postpone further matters for now and discuss them with the architect.

This is a new build and has 6m2 bathroom not bad! The walk-in closet is a joke, way too small and 11m2 children's room is also too small in proportion to the floor area.

The architect's design wouldn't be my thing either!

What is still missing is a site plan with width/length and building boundaries.

The architect/house seller's floor plan is actually not ideal either. However, at least a functioning staircase, garage, etc. Non-functioning bedroom/walk-in closet, children's room is a dark hole. Not a nice long hallway, slanted wall, etc. Takes into account the long side of the house facing southwest; in your case, it was northwest. Southwest is certainly more favorable for KfW40.

KFW Standard is. Compact etc. is accepted, but the office room is really not okay?

A lot is possible. But KfW is not just the shell; it's the overall concept. So which heating? Central or decentralized controlled residential ventilation?

But why necessarily kfw40? Because of the repayment grant?

Normally, with a monolithic block, the extra cost offsets the higher repayment grant again.

In your house even more so
