Is there a preferred position for Velux windows (closer to the original house wall or closer to the new exterior wall?) in the roof of a single storey extension to maximise light penetration into the original house?
I was going to place them midway between the two but I noticed that someone across the way has got them very close to the original house wall. The extension is three metres deep, the room behind which previously had a patio door to the outside, about 3.5 metres.
Also, is there any guideline figure for window area? We're looking at putting two 780 x 980mm windows in a 6 x 3m roof area.
Thanks for any advice.
