Because our plot is relatively long and narrow (20x43m (66x141 ft)), we have already given some thought to the possible arrangement of the house and garage. Here is the thread on that topic.

At first, we focused on the first variant with the garage located above the house to the north. However, with the garage and house together, it would have become very tight toward the south. The architect's first draft surprised us (garage on the east) but we generally liked it very much, so we are now presenting this as the basis here. Many of our wishes have already been met, and the draft is definitely a good starting point. I have to add that currently we do not have any eastern sun exposure and do not consider this a problem. The only drawback is that the house stands relatively centrally and garden space is “wasted,” partly due to the 6m (20 ft) setback on the east. But we will submit a preliminary building inquiry to possibly reduce the distance to 3m (10 ft).

So, here are the plans. North is at the top of the plan.

For the floor area, I would go for 2 full stories without knee walls and make it narrower instead.....
Advantage...cost savings, since the basement would then be smaller and cheaper..

But it is already 2 full stories without knee walls!? We don’t want a smaller basement at all.

Why a price limit, but more expensive components for KfW?
Why this orientation?
Why aren’t the bathrooms aligned vertically above the utility room...?
What did the KfW calculation show?

KfW was just an idea, but since we will probably use gas heating, that’s off the table anyway.
The orientation makes the most sense for us because of the street, garage, neighbors, etc. (we have discussed this for several months and keep coming back to it).
The bathrooms are actually located above the technical room...

Here, the focus is mainly on the revised floor plan, not on the further equipment of the house.

So in the pictures from your first thread, the utility room and kitchen are on the west side, and the bathrooms are on the east side... or am I seeing that wrong?

Are you sure about relying on an external operator for gas with ongoing costs, instead of, for example, an air-source heat pump combined with photovoltaic panels or something similar? That would reduce long-term maintenance expenses...

Regarding the full stories... you are right... I overlooked that... so there isn’t much that can be done with the basement...
