Walls of a new single-family house, ground floor runs crooked, defect correction construction defect

The shell builder has already admitted the fault. Again: It definitely is not the tilers' fault. The unevenness was only noticed by me after the tiles were laid. For better room visualization, I have attached the ground floor plan. The walls marked in green are crooked and the cause of everything. Maybe you understand everything a little better now. Perhaps I couldn't explain it properly without the picture.

Yes, and why couldn’t the tiler have noticed that himself beforehand? Didn’t he have a tape measure with him? In my opinion, he simply started in the corner and assumed (!) that all rooms are rectangular – which he should have checked beforehand, especially with the large areas.

Hello Dirk

Yes, and why couldn’t the tiler have figured that out himself beforehand? Didn’t he have a tape measure with him? In my opinion, he just started blindly in the corner and assumed (!) that all rooms are rectangular – which he especially should have checked beforehand with such large surfaces.

One thing fits the other ... two have found each other who complement each other excellently I am fairly sure that we won’t read anything about the result here on the forum if the OP actually hires an expert or lawyer ....

In the photo, the planarity is actually quite well achieved, at least in the front (camera towards the floor surface). What is crooked is the storage room. You will represent the stair area in color. That then has nothing to do with a 7.99 meter course. Of course, it can also be an irregular plaster, which is not supposed to be uncommon. I wonder why the bricklayer admitted to 8 meters in length, if only the stairwell is crooked. Maybe you should show four photos of the storage room, including the hallway area. Yes, and I expect from a tiler, if there is a difference somewhere, that he mediates or at least favors a flat and parallel joint layout in the visible area (here: door frame)!

It fits one to the other.... two have found each other who complement each other excellently. I am relatively sure that we will not read anything about the result here on the forum if the OP actually hires an expert or a lawyer....

Well, in the storage room, such a somewhat clumsily tiled transition wouldn’t personally keep me awake at night, but if the entire entrance area is poorly executed, the tiler should have thought about it beforehand. I can’t imagine that there is no other option, or am I wrong?

Hello Dirk,

Well, in the storage room a somewhat awkwardly tiled transition personally wouldn’t keep me awake at night either, but if it’s poorly done all around the entire entrance area, the tiler should have thought about it beforehand. I can’t imagine there is no other option, or am I wrong?

No, you are not wrong. If the tiler had measured properly, he would have noticed the difference and would have (had to) suggest a different laying method to the OP, where the wall alignment wouldn’t have mattered anymore; a larger tile size, in my opinion, would have already sufficed. By the way, I would also like to see the pictures around the stairwell.

Rhenish regards
