Knock down a house and build one 3 times the size. Pah. Smallfry. Just around the corner from Tewkesbury Ave there's a plan submitted to flatten 15 Westwood Park and build 9 (count'em) houses on the site. All that concrete should create a lovely waterfall into the properties down the hill on rainy days.
It really feels like anything goes around here. The house behind us has put up the most hideous loft conversion I have ever seen. It's like the roof has grown an enormous boil and where once there was sky there are now vertical roof-tiled (!) walls and windows staring into our living room. The council were not informed and neither did they need to be as it falls under permitted development.
All that said, with one or two exceptions there's not much of this estate that could be considered architecturally impressive. So while they don't impact on neighbouring properties - particularly on their views of London - the more interesting developments (like the prefab in Ringmore Rise) the better I say.
