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

The "empty space" is the attic and not the basement!

Oh, complete misinterpretation. Is it necessary to convert the roof?

Yes, for two HO places… they are needed :)

You mean the laundry room in the basement is not suitable? After all, it has a side window to the outside stairs and another light well, if I see that correctly.

The original poster apparently considers the conversion necessary. For a house built in '57, I don't need to imagine what the basement looks like ;) However, there are nice dry basements that can be developed. I think that while the kitchen can certainly be discussed overall here (everything else may more or less be well adapted to the existing structure), the focus should be on the question of whether the two-family house character can disappear. I still don't know where the front door is planned. I would also be interested in a few photos, especially of the outside and the staircase.

It is at least 5cm higher than the attic. :)
The entrance requires an outdoor staircase. Early kitchen planning is certainly very important here.

He is at least 5cm taller than the attic. :)

When you sit at a desk for 8 hours, the ceiling height is less important than air and light ;)
