Questions from Brixton
Do large lanterns overheat a room?
A large area of south-facing glass can make a room warm on sunny days. Solar-control glass, an opening vent and good background ventilation all help. Our guide on overheating explains the options.

The roof structure around it usually does. Your engineer or building control body will want the lantern's weight and the opening size.
