Every roof is different, so the survey decides what is practical for your Welwyn Garden City home. These are the loft conversion types we build.
Roof-light (Velux) conversion in Welwyn Garden City
The existing roof is kept and the loft is fitted out with floor strengthening, insulation, stairs and roof windows. It suits lofts that already have good headroom.
Rear dormer conversion in Welwyn Garden City
A box-shaped extension to the rear roof slope that adds headroom and floor area. It is the most common type of loft conversion on houses with a straight rear slope.
Hip-to-gable conversion in Welwyn Garden City
The sloping side of a hipped roof is built up into a vertical gable wall. It is usually combined with a rear dormer on semi-detached and end-of-terrace houses.
L-shaped dormer conversion in Welwyn Garden City
Two dormers joined across the main roof and a rear outrigger. It is typical on Victorian and Edwardian terraces and gives one of the largest loft spaces.
Mansard conversion in Welwyn Garden City
The roof slope is rebuilt at a steep, near-vertical angle with a flat top, giving the most floor area. A mansard normally needs a planning application.
