Hi Amanda, I don't like the sound of the floors dipping to the internal connecting wall. Was there a supporting wall directly underneath at sometime. If so you should see a boxed steel running across the ceiling directly underneath the wall upstairs. If this is the case, then it maybe that there has been some settlement on the steel.(this shouldn't be more than 5 or 10 mm at the most.) It would be a good idea to check with your surveyor when you bought the property. If you have no joy, then call round a good builder to have a look or ask for another survey (structural surveyor) to see why the floor is dipping. Hope this helps. Joseph
