We have already decided on this contractor. Here it is the case that we pay a one-time amount due to the redesign and can now plan as we like. Basically as a planning flat rate. As mentioned, the basis is the house shown in the initial post. That means the number of windows, rooms, etc. are included in the price. However, the shown house had one less room, which we have now added.
Regarding the floor plan design, we are somewhat freer. Of course, we cannot move thousands of walls now, but if some are removed, the general contractor wouldn't care.
The standard equipment with the contractor is already quite decent. We already liked many things in the model house. This was among other things the reason for the decision to go with this builder. Here we have already had some special requests included in the offer (ground floor fully tiled, remote-controlled shutters on all windows, TV and LAN sockets in all living/sleeping rooms).
It was quite clear to us early on that we want to build solidly, so this is not an option for us. We have anyway already committed to the contractor.
Yes, the exterior walls are 45cm and it will be built solidly. How thick are wooden stud exterior walls? 30cm?
As said, the contractor is fixed and this thread is about an optimal or good room layout.
Yesterday we also looked again at various narrow floor plans and experimented a bit more. Regarding the windows in the living area, we want to have as much light in the room as possible, but there must also be some space for furniture. Especially TV and sofa need some space. Also, the dining table for 6 people has to find a place somewhere.
Our sofa is quite large. It is about 3.15m x 1.40m. That needs space somewhere. And putting it in front of the window is somehow awkward, right?
Here is a picture:
