Hi fellow mners!
I was wondering if I could get any guidance on whether something like this will be ever permitted.
We’re in the process of buying a house that’s mid-terraced in the edge of London.
We love the property but not the front of the house, it has a typical 1970s look, with rusty red tile decorations!
The street has a uniform appearance and no one seems to have tried to change the colour or the tiles. 
Has anyone managed to get permission approval for altering the front exterior of a mid terraced house? How did you do it?
Thanks in advance!
