Gable-Fronted Dormer

A gable-fronted dormer features a triangular-shaped front that extends vertically from the roof's slope. This type of dormer adds significant headroom and can be used to create a large, open-plan living space. It's perfect for homes with a pitched roof, as it maintains the roof's original shape and appearance.
