This is a typical St Albans 1930’s semidetached home in need of extra space to the rear as the family is growing and is looking after an elderly relative. The extension takes advantage of the new Relaxation in the Planning Laws and is 6m deep. Four flat roof lanterns bring lots of natural light and ventilation into the very deep plan.
This is a very interesting project because it has highlighted a problem which is often overlooked by builders: you cannot have a low pitched tiled roof!!
If the pitch of your extension is lower than the pitches indicated in the list below, then you need to go for a flat roof as this is the only way to avoid having water stagnate on the roof tiles and eventually leak into your home. In this project a bad builder had not considered this problem and the Client had been left with a leaking roof five years after having the first extension built. We are all partial to tiled roofs, but sometimes we need to be practical and think of the long term durability of our extension. The result is a stunning space that has literally ‘changed the life’ of the users! Now the family of five, with two teenagers and a lovely Grandmother can all come together in the evening to eat, watch TV, chat and have lots of cups of tea!! The Client can’t wait for the Summer to come, when the house will open up to the garden and lots of family and friends will be coming round and enjoy the lovely space!
