Rooflight
Windows set into the existing roof. The least change to the outside of the house, useful where head height is already good.
A loft conversion uses the roof space you already have. We look at head height, the stair, and how the new rooms sit with the rest of the house before anyone talks about a dormer shape.
Dormer
A flat or pitched box built out of the rear roof. It is the usual way to gain a full-height bedroom and an en-suite.
Hip to gable
The sloping side roof is built up to a vertical gable. Often paired with a rear dormer on a semi-detached or end terrace.
L-shaped
A dormer that turns the corner of the roof. It suits houses where one straight dormer would leave an awkward leftover.
Mansard
The whole roof slope is rebuilt at a steep pitch with a flat top. More structure, more room, and usually a planning application.
