TYPES OF LOFT CONVERSIONS
Dormer Loft Conversion
A dormer is a structural extension that projects vertically from the existing roof slope, creating a box-shaped addition with a flat or pitched roof.
Hip-To-Gable Loft Conversion
A hipped roof has sloping sides that meet at a ridge — unlike a gable roof where the end wall rises vertically to the apex.
Mansard Loft Conversion
A mansard conversion involves replacing the existing rear roof slope with a near-vertical wall - typically at 72 degrees - topped by a shallow flat roof.
