I don’t see it that way. The load-bearing walls can stay, right?! … when turned in combination with spiral…
Spiral is exactly what I see as a stumbling block here on granite.
If it then becomes just a terraced house, at least you have a straight staircase. That’s surely what hits the mark, the heart of many prospective builders and pulls in the sales offer.
That’s why the straight staircase surprises me here, because it attracts the type “buyer, actually rather a builder,” who, to be blunt, “causes problems” with their dream house fantasies. Nothing needs to be drawn: terraced houses in metropolitan areas, especially if they are real plots instead of condominium ownership, would sell like hotcakes even in tax beige.
Yes, he probably couldn’t hear the endless “we actually wanted a straight staircase” anymore. The layperson doesn’t see that 1 or 2 rooms turn into storage rooms because of that.
Here, it’s probably more the professional who mercilessly looks through the cost-per-unit glasses on such projects. Every single eight-mark note counts, it adds up ;-)
