Hello, my question will be a bit of a design, but I do not have the opportunity to define a curtain around the elevator shaft. If we define it, all the projects will be drawn from scratch. I guess there is no such obligation. These gaps that we have made until now have always been curtained. This is the first time we encounter something like this. Is there any problem in the application?.. There is also a machine room in the attic. 1.5m above the roof slab and sits on bricks. I put beams on all four corners so that the bricks do not sit directly on the beams... on the bricks. will there be a problem?
