We have just renovated our south facing kitchen and dining. We have north east facing windows at the end of the dining area, but the kitchen is dark. I have always loved the look of skylights i.e a big pane of glass in the ceiling, but I've been told by a building designer that a South facing skylight will be too hot in the summer, and a heat loss in the winter. I am particularly worried by the heat in the summer. Does anyone have a South facing sky-window in their kitchen/living areas and could you tell me if you are happy with it or regret it? Attached is a picture for example of what we'd like to get.
