City villa with 165 sqm - first ideas?

I think you have overall very small / few window areas. Was that planned consciously?

It always depends on whether there are neighbors, how much privacy you want. Of course, if you live completely secluded or have a huge property, you can of course glaze everything, but I don't like to be on display. For example, we have even fewer windows in the living (residence) area, but rather more by the dining table. Sometimes you also want it to be cozy.

Your staircase made of #6 just doesn't work at all, and even if it did, the window to the right of the staircase would be extremely difficult to clean. Entrance to the living room should be single-leaf only, otherwise it looks rather poor. Otherwise, you especially lack storage space! The utility room can fit the technology, washing machine, dryer, and a small shelf, then it's full. A wardrobe fits under the stairs, okay. But where does the rest go? In the end, you'll just fill up the two "offices" with all sorts of stuff anyway...
