Which Loft Conversion Is Right for Your Home?
Dormer Loft Conversion
From £40,000The most popular option. A box-shaped extension is built out from the existing roof slope, creating full standing headroom and significantly more usable floor space. Ideal for most property types.
Hip-to-Gable Conversion
From £45,000The sloping hip on the side of the roof is extended vertically to create a flat gable end, maximising the internal loft area. Perfect for semi-detached and detached properties.
Mansard Conversion
From £55,000The most comprehensive option. The entire roof structure is altered to create near-vertical walls and a flat roof, delivering the maximum possible floor space. Often used in London terraces.
Velux / Rooflight Conversion
From £35,000The simplest and most cost-effective option. Rooflights are installed into the existing roof slope without altering the external structure. Ideal where headroom already permits.
