We've been Forest Hill residents for the best part of the past decade and we walk past it every day on the to and back from the station
We tried to get in touch with the owner/ developer quite a few times before the building got to its current state, but never had any replies. I'll try to take a snap next day or so when we walk past it to show you how severe the subsidence is. The middle of the house is falling in a V shape, which is clearly visible when you look at the windows!
