I have just been nosing a planning approval for a local house, which is to have a first floor bedroom added and a dining room. The dining room is to be added at the back, to what was the French windows to the garden.
The other end of the lounge is a wall with a door. Which basically means the lounge will have no windows at all, no light apart from that which comes through from the new dining room. Which means it will be awfully dark in the lounge. I thought (living) rooms had to have some natural source of light?
