Yes, seriously. Only the floor plan is important to me
Which on the one hand is not entirely true, because you also write
We only want floor-to-ceiling windows in the living area because we are building an urban villa style.
and on the other hand it tempts me, as expected, to two sarcastic remarks, namely: "you can’t tell from the floor plan in terms of quality" and indeed the previous hint that apparently the insignia of the urban villa look are also important to you.
I like to have a square house with a good floor plan
In my opinion, floor plans can only be combined with "good" and "square" by an "or," respectively it is a magic triangle: out of "good," "square," and "below 150 sqm floor area," only two can really be combined at the same time. I don’t want to preach to you — only you know what you like and I don’t have to be responsible for that — but I still want to give you these hints to think about (as well as that floor-to-ceiling windows are not a feature but a gimmick). In another place, you even hold a contradictory wish:
We then have a nice TV corner without windows
(which I also think is nonsense, but you see: you are not really consistently convinced yourself of your floor-to-ceiling dogma).
