Rear, side and wrap-around extensions with first-class finishing for homes in Ilkley
House Extensions 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 house extensions for homeowners in Ilkley (LS29) and nearby Otley, Guiseley and Harrogate.
Larger detached and period homes in Ilkley suit well-designed rear and side extensions, orangery-style additions and two storey wings. Because these properties are often high value and sometimes protected, we focus on careful detailing, matching materials and clear communication with your architect.
An extension is one of the best ways to gain living space without moving. BMK Joinery & Building Ltd handles the whole build, from groundworks, brickwork and roofing to bi-fold doors, roof windows and the internal joinery that finishes the room. Having joiners and builders in one team means the structure and the finish are planned together.
- Single storey rear and side extensions
- Two storey and wrap-around extensions
- Bi-fold doors, French doors and roof windows
- Brick, render and tile finishes matched to your home
- Steelwork, structural openings and open-plan layouts
- Joinery finishing: skirting, architraves, doors and fitted units
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.
Conservation area, listed building and local design policies can restrict what is allowed, and extensions often need full planning permission from City of Bradford Metropolitan District Council. We recommend speaking to your architect and the council early.
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.
