Twickenham has Victorian and Edwardian terraces around the town centre and St Margarets, riverside Georgian houses, and 1930s semis in Strawberry Hill and Whitton. Kitchen extensions and wraparounds on the terraces and wide rear extensions on the semis are the common Twickenham projects.
Budget guidance for Twickenham: expect £2,500–£4,000 per m² for a single-storey extension, which puts a 25–30 m² kitchen extension at £75,000–£120,000; two-storey and wraparound schemes are priced on the structure involved (see our house extension cost guide). Twickenham Riverside, Twickenham Green, Queen's Road and St Margarets are conservation areas, and Richmond upon Thames Council looks closely at roof and front alterations. Where approval from Richmond upon Thames Council is needed, our design team prepares and submits the application.

Loft conversions in Twickenham
Twickenham's Victorian and Edwardian roofs suit rear dormers; the semis take a hip-to-gable and rear dormer for a master suite.
Typical London figures are £25,000–£45,000 for a Velux conversion, £45,000–£75,000 for a dormer and £60,000–£100,000+ for a mansard (details in our loft conversion cost guide). Every Twickenham loft quote follows a measured survey of the roof, head height and stair position, and includes Building Regulations sign-off, fire doors and structural calculations.

Common questions about building in Twickenham
Do I need planning permission for an extension in Twickenham?
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 Twickenham are in the Twickenham Riverside, Twickenham Green, Queen's Road, St Margarets Estate, Strawberry Hill Road and Cole Park Road conservation areas, where side extensions, two-storey rear extensions, cladding and roof additions need permission. Article 4 directions on Cole Park Road and parts of the St Margarets Estate also control front-facing extensions, roofs and porches, and basements need permission borough-wide.
What does Richmond upon Thames Council expect for loft conversions in Twickenham?
The council's House Extensions and External Alterations SPD (2015) says dormers must not rise above the ridge, should leave roof visible below and either side, and should not go on the front; raising the ridge is normally unacceptable. In a conservation area a dormer needs planning permission. The Twickenham Village Planning Guidance SPD (2018) assesses each conservation area, and separate SPDs cover St Margarets and Strawberry Hill. On the ground floor, the same 2015 SPD usually accepts single-storey rear extensions of 3m on a terrace, 3.5m on a semi and 4m detached.
What does a dormer loft conversion cost in Twickenham?
Twickenham's Victorian and Edwardian terraces usually take a rear dormer, which typically costs £45,000–£75,000, or £55,000–£85,000 for an L-shaped dormer, both including VAT. Head height and stair position decide where a project lands. For the ground floor, a Victorian side return extension is £65,000–£130,000 at mid to high specification, including VAT. Our dormer loft conversion cost guide has the breakdown.
