Loft Conversions & Dormers in Leeds
Create new bedrooms, offices and bathrooms in your roof space
Loft Conversions & Dormers by BMK Joinery & Building
A dormer or loft conversion adds real floor area and headroom without using any of your garden. We build timber-framed dormers, form the structural openings, fit insulation, roof windows and cladding, and leave the space ready for plastering and decoration.
Dormer work needs accurate carpentry and a watertight roof. Our team frames, weatherproofs and finishes each dormer carefully, including slate or tile cladding, flashing and fascias, so it looks right from the street and performs through a Leeds winter.
