Home Extension Contractors in Brighton & Hove

Rear extensions | Side returns | Wrap-around builds | Loft conversions | Garage conversions

Brighton & Hove’s characterful housing stock is packed with potential—but many homes are short on modern, open-plan space. A thoughtfully designed extension can transform day-to-day living, boost EPC ratings, and add six-figure value in today’s buoyant coastal market. Safe-Bricks Limited is the city’s dedicated design-and-build home-extension contractor, delivering turnkey projects that honour heritage fabric while meeting contemporary standards for comfort and efficiency.

Extension Solutions We Build

Rear Kitchen-Diner Extensions

Steel-supported opening to garden, roof lights for daylight, under-floor heating beneath polished concrete or parquet.

Side-Return Infills

Gain 1–2 m of width along a Victorian terrace—perfect for islands, larders or daybeds.

Wrap-Around Ground-Floor Additions

Combine rear and side infills for the largest footprint increase; often paired with full-height glazing and zinc roofs.

Loft & Garage Conversions

Extra bedrooms, en-suites or home-office studios with upgraded insulation, dormer windows and concealed storage.

Basement Conversions

Specialist tanking for bungaroosh foundations, mechanical ventilation and heritage-compliant lime renders.

Planning, Conservation & Building-Control Pathway

Permitted Development can cover modest single-storey rears, but check height, eaves and materials.
Conservation areas (Brunswick, Clifton Hill, North Laine, etc.) require lime renders and period-appropriate fenestration—learn more in Rendering in Conservation Areas — Dos & Don’ts.
Listed Buildings demand Heritage Impact Statements; Safe-Bricks prepares all documentation and liaises with council heritage officers.

Materials & Envelope Performance

Older Brighton walls lose significant heat; we routinely pair extensions with breathable mineral-wool external-wall insulation finished in silicone thin-coat render. See Traditional & Modern Rendering - The Safe-Bricks Service Guide.

Working on bungaroosh? Our team follows the salt-draw and hot-lime methods described in Rendering Bungaroosh Walls — Specialist Techniques & Pitfalls.
