Floor plan design single-family house 150 sqm - tips for improvement?

I just wanted to mention it. Not that your house ends up being more expensive than mine .

You have the single-story specification in the development plan. The architect can't just magically remove that. So why do you leave the appointment and she draws you 3 stories?

I just want to understand!

As written:

[*]Basement living area: Usually allowed to protrude 1.40 m from the ground – implemented accordingly so it is not considered a full story.
[*]Ground floor: Full story
[*]Attic: Maximized so that it is not considered a full story

It's okay. UG = basement, EG + DG. It's only one story in total.

Good to spread everything over 3 floors.

The ground floor has the fewest restrictions and the largest living area with the smallest room program.

I will post the basic information here again shortly, that goes without saying!

Apparently not: You have been on board long enough to know that this "belongs" in post #1, not in post #40 :-(

we had 8 other offers for comparison.

Don’t forget that large differences between offer amounts are more an indication of inexperienced bidding than "proof of functioning competition".

The current offer is definitely not the "cheapest"!

At the time, I took the trouble to list and compare all the items of the respective providers in an Excel sheet. For example, if a multi-utility house entrance or the angle supports were missing in an offer, I naturally included the expected amount for them in the calculation, because otherwise I can't make a "fair" comparison.

That is good if you take the trouble
