Saw it last night, sheesh they have their work cut out. Them and the council planning team must feel like they are trying to juggle jelly.
Where I live (Hounslow) the amount of dreadful work, dodgy back yard extensions and loft conversions that are going up is unbelievable. Why anyone would use really bright new (and cheap bricks) to extend a Victorian house is beyond me.
The guy across the street has just converted a 3 bedroom house into 4 flats and a bedsit. Permitted Dev for the loft and extension was done with planning permission. But he did not get permission to change it into flats as he knew he wouldn't get it if he asked. The place was just turned into a pig sty with the beautiful old established front and back garden being concreted over. No proper bins hot and cold running rodents.
I mentioned it to the council and he has now been refused retrospective permission to change it into flats. He wasn't paying council tax or declaring the income either.
Enforcement order to turn it back into a family house is coming out soon. Local people have to take a stand against this type of thing. If no one complains then nothing gets done.
If you see it in your area mention it and keep mentioning it until they do something. Contact your MP - at the moment they may be keen to be seen to do something!
Sorry for the rant but it REALLY annoys me (as you may have guessed!)
