- HOUSE EXTENSIONS
House Extensions in Richmond — Period Sensitivity, Modern Space
Richmond's varied housing stock creates opportunities for every type of extension. The Georgian and early Victorian properties near Richmond Green and Hill respond well to carefully designed rear extensions in sympathetic materials. The larger Edwardian and interwar detached properties across East Sheen and Kew offer scope for side, rear, and double-storey additions. Almost all require planning permission due to the borough's extensive conservation area coverage.
Extension Types for Richmond Properties
Rear Extensions — The most achievable extension type across Richmond. Single-storey rear additions that respect the character of the existing property are regularly approved. Typical costs: £58,000 to £100,000.
Side and Wraparound Extensions — The larger plots in East Sheen, Kew, and parts of Ham offer scope for side extensions and wraparound additions that maximise the ground-floor footprint. Typical costs: £75,000 to £125,000.
Double-Storey Extensions — For detached and semi-detached properties where the plot and planning context allow. Adds living space and bedrooms. Typical costs: £110,000 to £200,000+.
Orangeries and Garden Rooms — Popular in Richmond where homeowners want a transition space between house and garden. Brick bases with extensive glazing, often in a style that complements the period architecture. Typical costs: £60,000 to £100,000.

- LOFT CONVERSIONS
Loft Conversions in Richmond — Adding Bedrooms to Period Homes
Richmond's Victorian and Edwardian properties typically have generous roof spaces with good conversion potential. The larger detached and semi-detached properties in TW9 and TW10 can accommodate substantial loft conversions that add a full master suite or multiple bedrooms. Conservation area restrictions mean planning permission is usually required.
Loft Conversion Types for Richmond Properties
Rear Dormer Conversions — A flat-roofed rear dormer preserves the front elevation while creating spacious rooms. The most commonly approved type in Richmond's conservation areas. Costs: £52,000 to £78,000.
Hip-to-Gable Conversions — Ideal for the semi-detached and detached properties with hipped roofs common across East Sheen and Kew. Extends the hip to a gable wall, combined with a rear dormer for maximum space. Costs: £58,000 to £82,000.
Mansard Conversions — Premium option for terraced properties in Richmond town centre. Requires planning permission and careful design. Costs: £70,000 to £100,000+.
L-Shaped Dormers — For larger properties where both rear and side dormers are achievable. Maximum loft floor area. Costs: £65,000 to £92,000.

- RENOVATIONS
Renovations in Richmond — Preserving Character, Delivering Comfort
Richmond's period properties deserve renovation work that respects their architectural heritage while delivering modern comfort.

Typical renovation costs in Richmond: kitchen renovation £30,000 to £65,000, bathroom renovation £14,000 to £30,000, structural reconfiguration £7,000 to £15,000, whole-house refurbishment from £110,000 upward.
