Over the years kitchen extensions and Orangeries have got bigger and bigger in size. Having a large kitchen dining room is a very fashionable thing but then leaves the problem of natural lighting.
This can be overcome on a flat roof by installing roof domes or an Orangery roof.
There are various sizes and styles of domes which can be opened electronically / manually or fixed allowing natural daylight into your room.
Orangeries can be a lovely centre piece for a room allowing plenty of light and can be lit up at night with nice lighting.
