The Flat is built in UK London between 1900-1929.
The ceiling is smooth, and from the looks of it, the plaster ceiling is lath & plaster.
I was told by the structural engineer (who came to inspect the building stability after the plaster ceiling collapse) that this sort of ceiling do not contain asbestos.
Is it right for him to say that without lab testing?
Any risks of asbestos exposure living in the room, one floor above? (if there even is any asbestos in it)
