Floor plan single-family house ~165m² plus basement

@11ant Is it also okay for you if we reduce to 85 cm on the upper floor and it would be 94 cm on the ground floor?

I personally neither work at your building authority nor do I have any shares in it. 85 cm on the upper floor could be tight, you have to meet 90 cm (but probably at the top edge of the window frame, I have never dealt with pushing it to the absolute limit). On the ground floor you could also be lower. At which height countertops, faucets, sofa backs and the like are swung over without scraping is something only you can know on a case-by-case basis. Stone cutting at this height is uncomplicated, but I would still not go below 5 cm.

Without looking at the pictures, it should be noted that you must not compare RBM with the upper edge of the finished floor.

I personally neither work at your building authority nor do I have any stake in it. 85 cm on the upper floor could be tight, you have to meet 90 cm (but probably at the top edge of the window frame, I have never dealt with pushing the limits to the very last drop). On the ground floor you might also be allowed lower. At what height countertops, faucets, sofa backs, and the like can be swung over without scraping is something only you can know in each individual case. At that height, cutting stone is uncomplicated, but I would still not go below 5 cm.

Why do I have to meet 90 cm? I think it should be 80 cm since we are below the 12m fall height. These are all rooms without countertops, no faucet, no sofa, none of those. What do you mean by cutting stone being uncomplicated at that height? Is it then automatically complicated on the ground floor? Is that why I have full stones on the ground floor and a half stone on the upper floor?

RBM = raw construction measurement

top edge of the finished floor = top edge of the finished floor

correct?

The 85 cm top edge of the finished floor would be the target from my point of view, right?

I don't check before every answer in which federal state the questioner is building. Yes, in many federal states, eighty is sufficient.

What do you mean by brick cutting being uncomplicated in height? Does that automatically mean it is complicated on the ground floor? Is that why I have full bricks on the ground floor and a half on the upper floor?

That has nothing to do with height above ground. I meant that the bricks are uncomplicated to cut horizontally (as opposed to vertically / parallel to the webs, where chipping of the webs—and often hack jobs—occur). If the shell builder only lays normal bricks without special edge bricks, you reach 100 cm after four layers from the raw floor (i.e. 85 cm from the finished floor). For 80 cm, the fourth layer of bricks must already be cut in height here. This is usually done to measure; hardly anyone uses prefabricated half-height bricks for this. An 11ant type house would of course be planned to minimize waste here, but currently no general contractor has such in their program. So far, only 11ant Edition co-planned houses are quietly in the pipeline but will also only arrive in 2024 ;-)
