Can I rent out a garden annex?

This depends on your planning permission conditions. Some approvals restrict use to 'ancillary' accommodation for family only, while others permit independent letting. We recommend discussing your intentions with your installer at the feasibility stage.

How much does a garden annex cost?

Garden annexes typically start from £65,000 and range to £120,000+ depending on size, specification, and finishing level. While this is more than a standard garden room, it's significantly less than a traditional extension or buying additional property.

Garden Annexe in West Drayton, Middlesex

West Drayton has been transformed by the Elizabeth line, which now delivers fast, frequent services to Paddington, Bond Street, and Canary Wharf. This connectivity has attracted a new wave of professional buyers to an area that offers good-sized gardens and competitive property prices relative to zones further east — making home improvement investment here increasingly timely. West Drayton's mix of 1930s semis and more recent development provides a range of garden sizes suited to compact and medium-sized garden room builds. As Elizabeth line commuters increasingly shift to hybrid working patterns, demand for purpose-built home offices and studios is growing quickly in this area.
