Richmond has Georgian and Victorian townhouses around Richmond Hill and the Green, Victorian terraces in the town centre and Kew, and Edwardian houses towards North Sheen. Kitchen extensions with garden glazing and orangery-style rear additions are the common Richmond projects; basements suit the townhouses where gardens are shallow.
As a guide, a well-built single-storey rear or side-return extension in Richmond costs around £2,500–£4,000 per m² including structure, glazing and finishes, so a typical 25–30 m² kitchen extension lands between £75,000 and £120,000. Our house extension cost guide explains what moves the price. Richmond Hill, Richmond Green, Richmond Riverside and Central Richmond are conservation areas, and Richmond upon Thames Council looks closely at roof and front alterations. We confirm permitted development rights at the first visit and handle any application to Richmond upon Thames Council through our design team.

Loft conversions in Richmond
Richmond's Victorian terraces usually take rear dormers, kept below the ridge and off the front slope; the Georgian houses have limited roof space and need a conservation-led design.
In London a Velux conversion costs £25,000–£45,000, a dormer loft with a bedroom and en-suite £45,000–£75,000 and a mansard £60,000–£100,000+; our loft conversion cost guide sets out what is included. We survey the roof structure, head height and stair position before we quote a Richmond loft, so the figure reflects the actual roof rather than an assumption.
Renovations and refurbishment in Richmond
Richmond renovations are period restorations of Georgian and Victorian houses combined with modern kitchens, bathrooms and services. Typical Richmond refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. Our Victorian terrace renovation cost guide gives realistic budgets, and every Richmond project runs on a JCT contract with a written specification and our 10-year workmanship warranty.

Common questions about building in Richmond
Do I need planning permission for an extension in Richmond?
Houses (not flats or maisonettes) keep national permitted development rights for a single-storey rear extension (3m attached, 4m detached, or 6m and 8m with prior approval) and most rear dormers (40 cubic metres on a terrace, 50 otherwise). Richmond upon Thames Council decides applications. Parts of Richmond are in the Richmond Hill, Richmond Green, Richmond Riverside, Central Richmond, St Matthias and Sheen Road conservation areas, where side extensions, two-storey rear extensions, cladding and roof additions need permission. An Article 4 direction in Central Richmond and Richmond Riverside removes further rights on certain streets, and any basement needs permission borough-wide.
What does Richmond upon Thames Council expect for loft conversions in Richmond?
The council's House Extensions and External Alterations SPD (2015) sets the rules. Dormers should sit below the ridge, be set in from the sides with roof left visible below, and should not go on the front slope; raising the ridge is normally unacceptable. In a conservation area a dormer is not permitted development, so it needs planning permission. The Richmond and Richmond Hill Village Planning Guidance SPD (2016) adds a character assessment for each conservation area, listing the features to protect.
What does a mansard loft conversion cost in Richmond?
For Richmond's period townhouses and terraces, a mansard loft conversion typically costs £60,000–£100,000+ including VAT, and prime central schemes £120,000–£150,000. Where a townhouse has a cellar, converting it is £2,500–£4,000 per m², about £80,000–£150,000 for 30–40 m², excluding VAT. Roof structure, access and conservation requirements move the figure most. Our mansard loft conversion cost guide sets out what is included.
