Loft conversions turn unused roof space into a habitable room such as a bedroom, office or en-suite, with the structure and work varying by roof type. The main types are: Dormer – a structural box projecting from the roof slope to add full-height headroom and windows; Hip-to-Gable – extending a sloping hipped side out to a vertical gable wall to gain volume on semi-detached and end-of-terrace homes; Mansard – rebuilding one or both roof slopes to a near-vertical profile with a flat roof above for maximum space, often requiring planning permission; Velux / rooflight – keeping the existing roofline and fitting windows into the slope where headroom already allows; and L-shaped – combining a main rear dormer with a second dormer over the rear-addition outrigger on period terraces. Across all types the work covers structural alterations to the roof, new floor joists, staircase installation, insulation to current Building Regulations, and full internal fit-out.
