Floor plan optimization, renovation of a two-family house into a single-family house, built in 1957

something like that would make sense, with or without doors.

Thanks for the suggestion for the kitchen planning. Yes, the kitchen is actually a bit too big. It is filled much better this way! We definitely need to plan something (a block or something similar) in the free dance space. I like your idea of an open kitchen. I can hardly imagine it as a closed kitchen with doors because otherwise the kitchen would be split in two by the walkways.

I would hardly or not at all change the basement. Why do you want to tear everything out there? That would be structural nonsense. Take the best room and make it nice as an office – I would tend to use the laundry room. (How does the window actually fit in with the terrace there?)

Thanks for the suggestion for the extension; we had not considered anything in this direction so far. I would like the open entrance area with the relocation of the front door and the toilet. However, I don’t know to what extent this is feasible. The building envelope is already fully utilized at that point, and in front of the house there would be quite a few stairs. From the street to the front door on pedestal height, there are currently already six outdoor steps.

The basement is actually supposed to remain largely as it is and is in a good dry condition. We initially considered using the basement room that is accessible straight ahead from the stairs as an office. But we actually imagine a working day in the attic with a large roof window to be more pleasant than in the basement. It is currently also unheated and if the basement ceiling still needs to be insulated, then the ceiling height is not generous.

I still don’t know where the front door is planned. I would also be interested in some photos, especially outside and of the stairs.

So far we thought of leaving the front door where it is. Here is a "photo" of the entrance area from outside. I actually have no photos of the indoor stairs at the moment. I’ll do that next time I’m there.

(How does the window actually fit in with the terrace there?)

The terrace door/exit from the dining room should actually not be a problem. The basement window has a light well.

Nice project. But you go down a few steps again on the ground floor level in the house, right? Maybe it's better to leave the staircase where and how it is and use the money for something else - e.g. for dormer windows. It can still be spruced up.

You then go up a few more steps inside the house to the ground floor level, right?

Yes, exactly. Inside the front door there are still 6 steps up to the ground floor. At least the exit to the garden and the garden on the south side are then level.

I can hardly imagine it as a closed kitchen with doors, since otherwise the kitchen is divided by the walking paths.

But that was not necessarily assumed or desired?! I recall:

open kitchen, kitchen island: closed kitchen is also fine

Personally, I wouldn’t put tall cabinets in the middle of the kitchen that would block light from the window and the view of a cozy counter/island when entering, but in principle I find it nicely solved: work area at the back, breakfast and guest zone in front.

Attic office can be a challenge in summer. I would at least set up a backup space in the basement.

That was not necessarily assumed or desired?! I remind you of:

Yes, correct. The kitchen may be open or closed. The solution should be coherent overall based on the circumstances, and I just don't want the kitchen to necessarily be the passage room for everyone. My comment referred to the fact that evelinoz said that her proposal works - whether open or closed. It definitely makes sense to use the space in the middle as in the proposal.
