Gabled dormers feature a pitched roof with two sloping sides that meet at the ridge. This design allows for better ventilation and can accommodate larger windows, providing ample natural light. Gabled dormers are an excellent choice for properties with pitched roofs, as they complement the existing roof line.

Example: A gabled dormer with a large Velux window installed in a terraced house in London.
