Loft Conversions & Dormers in Horsforth by BMK Joinery & Building
Horsforth is one of the larger suburbs on the north-west side of Leeds and an area we cover regularly from our LS16 base. We provide loft conversions & dormers for homeowners in Horsforth (LS18) and nearby Cookridge, Guiseley and Pudsey.
Loft space in 1930s to 1980s semis and detached houses around Horsforth is often well suited to a rear dormer, adding a bedroom and en-suite without changing the front of the house. Many bungalows can also take a dormer or roof lift to create bedrooms upstairs.
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.
- Flat-roof and gable dormers
- Timber frame, insulation and weatherproofing
- Slate-effect, tile and zinc cladding
- Roof windows and window installation
- Structural steelwork and floor strengthening
- Staircases and access to the new room
Building and joinery in Horsforth
Horsforth mixes Victorian stone terraces near the older centre with interwar and post-war semis and newer estates further out. That variety means everything from side-return extensions on terraces to dormers on semis and full kitchen refits.
Many loft conversions fall under permitted development, subject to volume limits and materials. Building Regulations approval is always needed and is signed off by Leeds City Council building control or an approved inspector.
Horsforth falls under Leeds City Council. Some older parts of the area may sit within conservation areas, so we check early whether permitted development rights apply to your house.
