The workers were indeed trying to go through the floor and into our flat! The had bought huge pipes, the kind that are used outdoors to connect the house to the sewer systems, and they wanted to connect these pipes from the bathtub drain across the bathroom and then on to the outside sewer system. But in order for them to fit they decided that they would have to go through the ceiling in my bathroom and then on and out through the wall of my bathroom. They said they wanted these big, huge pipes so that there would never be a problem with the drains getting clogged. (Maybe they think people are in the habit of using the bathtub as a toilet!!)
They'd managed to knock away the floor up there so that the ceiling is only about an inch thick! I suggested they could just continue on knocking out the hole and put in some steps and share our bathroom. They have revised their original plans and today they are upstairs trying to sort out their near disaster. Now, not only is there banging going on, there's lots of shouting and yelling too because Mustafa has decided that since the new neighbour can't manage to supervise his workers than he will do it.
hmmm... maybe I should get a pot of tea going just in case
By the way... I'm switching my blog to the new Beta version. You'll have to be a bit patient while I make sure all the links and things work.
