Fill the plastic bucket next to the door immediately with salt or grit, otherwise you might have to crawl on all fours to the garage when it's icy in winter. But that's how it is now.
So get yourself a long angle bracket on loan from the carpenter to check if they haven't left hollow walls. This often happens because the Achmeds do it piecework. You can't see it with the eye yet, but later on with the door frames, for example. Karsten
There are no Achmeds. And I don't think you can call it piecework with 2 rooms and one chamber in one day (preparations were already made the day before).
