Loft Conversions & Dormers in Ilkley by BMK Joinery & Building
Ilkley is a Wharfedale town on the edge of the moors, and a place we are glad to work in. We provide loft conversions & dormers for homeowners in Ilkley (LS29) and nearby Otley, Guiseley and Harrogate.
Larger period and detached homes in Ilkley often have generous roof voids. A well-proportioned dormer or Velux conversion can add a principal bedroom suite, and we pay close attention to materials such as slate-effect cladding and tile to suit the property.
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 Ilkley
The town is known for Victorian stone villas, terraces and substantial detached homes. Joinery, extensions, loft rooms, staircases and period-style windows and doors are all well suited to properties of this type.
In conservation areas and on listed buildings, permitted development rights for dormers are limited, so a planning application to City of Bradford Metropolitan District Council may be needed. Building Regulations approval is required in every case.
Ilkley is covered by the City of Bradford Metropolitan District Council rather than Leeds, and has conservation areas and listed buildings, with some Article 4 controls. Please confirm what applies to your address; we are happy to help you check.
