Our expertise lies in adding and maximizing unused space to provide you with the room you require.

Mansard Loft

During a mansard loft conversion in Wimbledon, the rear of your property is utilized. This involves modifying the roof slope to form a horizontal roof and a steeply sloping back wall. Mansard conversions in Wimbledon are highly sought-after for the spacious rooms they produce.

Dormer Loft

Dormer loft conversions in Wimbledon are highly sought-after among terraced or semi-detached homeowners. This type of loft conversion features a box-like structure extending from the roofline, creating additional headspace and floorspace in the new area. Notably, the existing roof structure remains unchanged structurally during this process.

Rooflight Loft

If you're in need of an affordable solution for an additional room or working within a budget, our VELUX® windows loft conversion in Wimbledon is an ideal choice. This cost-effective option maximizes interior space functionality by installing new windows on the roof, flooding the area with natural light, and creating a bright, functional new space.

Hip to Gable Loft

If your loft has a pitched roof, you may find limited headspace. A hip-to-gable loft conversion in Wimbledon can address this issue by building up one of the side slopes into a gable wall. This effectively increases headspace and creates a larger usable space.
