Single-family house design 250 m², 2 full floors with hipped roof

Where is your architect? Do you want to build 250m² without a permit? According to German law, you have to pay an architect anyway who draws the plans for you. Why don’t you ask him first? He can explain and calculate many things for you that would only fill countless useless pages here. With the result, we can then perfect the details.

Are you seriously going into the detailed planning with this terrible floor plan? It would be very sad if such an unusable house is built on this huge area
