@11ant was mistaken here. According to my calculation, the diagonal inside the house is not even 1 m (7%).
11ant was neither mistaken nor claimed otherwise. It is just under eight quarter-meters, so just under two meters diagonally across the property. Within the house footprint, therefore probably 1 m, according to my basement rule thus 50% basement costs allocated to the cost center terrain modeling / slope stabilization ...
This is easily possible without a basement. Also without significant retaining walls, if you don’t want a level plot. Where should the house be placed?
... of course it is possible without a basement (but then with "L-beams" & co at about half the cost of a basement). The tricky part here is that the terrain profile does not at all lend itself to rotating the house axis parallel to the contour lines.
The nasty thing here is that the terrain does not at all lend itself to rotating the house axis parallel to the contour lines.
How do you come to that conclusion? I don't see any building line. There is no law (except the development plan) that prohibits placing a house diagonally on the plot or, in other words, you don't have to build it parallel to the street.
Quite a few plots seen here would benefit from that.
Here it looks like this:
You can assume that the file in the original post is aligned north since the text is almost straight. I only had to rotate it because the program isn’t very flexible. So: the street is north.
