new extension is permitted 3m depth from house and we are re-using 3 velux along the 7m width.
not sure whether to have the ceiling inside pitched or flat. keeping it flat will supposedly reduce the amount heat from sunlight, but maybe reduce light into lounge. but pitched might make space seem bigger, with more light, but more heat. extension is kind of SE so not excessively hot, but summer mornings are very hot for a while.
choice of ceiling dictates choice of lighting and I'm no where near making mind up.
what do you have and why? would you change it???
thank you
