Optimize new single-family house floor plan

If 3 full storeys are required, the third storey must also meet the criteria of a full storey.

Additional info: A 3rd floor must be built in the area, which was not clear before.

Are you sure you have read the development plan correctly?

The difficulty is that the plots are awarded by the municipality (we do not have it yet) through a bidding process. Usually, 2-3 floors are allowed. However, one must submit floor plans of the planned development with the bid, and only those planning 3 floors will be considered. The 3rd floor may be at most 2/3 the size of the one below.

A third floor must be built in the area, which was not yet clear before. Therefore, our conclusion was to relocate some things there.

If three stories are desired, it is worth planning three stories from the beginning. All the compartmentalizing of children's rooms can be avoided if one breaks the axiom that household members sleep on the same floor.

We did not start with the upper floor. Did it say that somewhere? Then I must have overlooked it.

No, it was nowhere stated. The advice was to do this: first plan the first upper floor, then the ground floor. That makes everything easier.

The difficulty is that the plots are allocated by the municipality (we don't have it yet) through a bidding process.

Did I overlook that?

Actually, 2-3 floors are allowed. The 3rd floor may be at most 2/3 the size of the floor below.

So circled II + D?

However, you have to submit floor plans of the planned development with the bid, and only those planning 3-storey buildings are considered.

Oh dear, said Lottchen. We once had a case here – I think in Pforzheim or the surrounding area – where even a jury evaluated the buildability of the design before awarding the plot. So things can always be a bit more stringent. Clarify the conditions further. You should probably plan II + D (or II + attic floor?), which would already make a significant difference in how it would need to be designed.

The entire children's room juggling can be avoided if you break the axiom that household members sleep on the same floor.

Yes, with three children and the oldest being six years older than the youngest, it really suggests itself to "outsource" the oldest into a forced additional floor. As long as they are all still so young, they generally won’t all want individual bedrooms yet. How is the brood composed (boys/girls, are there twins...)?
