Newly built semi-detached house 155 sqm - orientation & floor plan accordingly

In my opinion, it is not a good idea not to separate the DDH. The heavyweight wall transmits sound little but noticeably. How should the energy costs be divided?

The non-separation arises from cost reasons and the architect's opinion that a shared wall is similarly good as two separate walls. It will come down to a heat pump with separate meters and, if possible, separate photovoltaic systems.

Why won't it happen? - Point symmetry instead of axial symmetry is also an alternative.

So it will not happen that the two halves are not aligned in a line, perhaps I expressed myself incorrectly.

What is point symmetry?

A separation of living room and kitchen would lead to the floor plan in post 13, right?

If you consider it as a rough sketch, yes. As I already said: the staircase guides the floor plan!

I never said it wouldn't be accepted, I just wanted to understand why the swap is better for you. I can understand the reasons and would actually be open to the swap.

Well, you ask a lot of questions, and that is okay and good. But you also have to step out of your shell and say yourself what you like or don’t like. This is not about praise or our opinion, it’s about your house.

will be changed to a heat pump

Where is the outdoor unit supposed to be placed? Or will it be an indoor unit?

What is point symmetry?

A reflection about two axes, meaning the adjacent half is not "reflected" but "rotated 180°".

If you consider it as a rough sketch, yes. As I said: the staircase determines the floor plan!

Well, you ask a lot of questions, and that is okay and good. But you also have to come out of your shell sometimes and say what you like or don’t like. It’s not about praise or our opinion here, it’s about your house.

We generally like the floor plan I uploaded in the first post. Also with the rear building boundary. But new input (north side not so bad after all, aligned with neighbors) raised the question whether we gave up on the north side or the orientation to the north too quickly. The problem is that we don’t like any floor plan so far because we want to include both north and south if we have two terraces there. Simply continuing to use the previous floor plan and shifting to the front building boundary does not solve the “problem” of the living area on the north side. Entrance on the south side takes away the good light, and we haven’t found a floor plan with a side centrally located entrance that we like.

The outdoor unit is planned either as an indoor unit or by the carports, this still needs to be discussed with the heating engineer.

Your first floor plan also had the north terrace accessed from the hallway/entrance area. So I don’t see what is wrong with Yvonne’s floor plan idea. I like that you keep responding to our questions, but unfortunately for me, they still often come afterwards. Have you looked at the simulated sun position of your property by now? That looks great even in the north garden. Of course, no direct sun in the north rooms, but still quite a lot in the garden, because (if I’m correct with my research and I’m not posting the image due to data protection) there is no development directly east and west of it. Only your house casts a shadow to the north. That can’t be all that bad. Somehow it seems to me that you are putting the cart before the horse, with wrong assumptions/thoughts. Well, you’re probably pondering yourselves already. So I’ll wait to see what conclusion you come to regarding the orientation of the rooms.
