Extensions

Transforming homes across Gloucestershire — thoughtfully designed, expertly built.

An extension is one of the most effective ways to transform your home — adding space, light, and value without the upheaval of moving. At Thorn Homes, we manage everything from planning and structural design through to final fit-out, so you have a single point of contact throughout.

We work closely with our sister company PSK Architect to ensure design and build are fully aligned from day one — delivering better results, fewer surprises, and a smoother process for our clients.

Single-Storey Extension

Single-Storey Extension, Winchcombe

A stunning single-storey extension that draws on the best of traditional craftsmanship. Vaulted ceilings with exposed oak beams and natural stone walls create a space that is warm, characterful, and entirely individual. A striking round window becomes the focal point, complemented by oak-framed doors and windows throughout.

Welsh slate roofing and conservation roof lights complete the picture — a space that blends character, durability, and timeless style in equal measure.

Rear Extension

Rear Extension, Hatherley, Cheltenham

A bright, open-plan living transformation featuring a spacious kitchen and dining area with a central island at its heart. Matching cabinetry ties the kitchen and cloakroom together seamlessly, while a new downstairs bathroom adds practicality to the layout.

Two large sliding doors maximise natural light and create a seamless connection between inside and garden. The exterior is finished with Cedral cladding for a clean, contemporary look that requires minimal maintenance.
