Learn more →House and kitchen extensions in Wimbledon
Wimbledon is Victorian and Edwardian terraces in South Wimbledon and Wimbledon Park, larger Victorian and Edwardian houses on the Village hill, and 1930s semis towards Raynes Park and Merton Park. House extensions in Wimbledon are mostly side-return and wraparound kitchen extensions on the terraces, with wide rear extensions and orangery-style additions on the Village houses; two-storey side extensions are common in Raynes Park.
Wimbledon Village, Wimbledon Park, Merton Park and John Innes are conservation areas where Merton Council expects rear-only roof changes and matching materials. Most Wimbledon extensions we price fall between £2,500 and £4,000 per m², so a 25–30 m² kitchen extension is roughly £75,000–£120,000 fitted out; our house extension cost guide breaks the numbers down. We check permitted development rights at the first visit and deal with Merton Council in-house.

Loft conversions in Wimbledon
Loft conversions in Wimbledon are usually L-shaped rear dormers on the terraces and hip-to-gable conversions on the semis; Village houses often have room for two loft rooms and a bathroom.
Expect £45,000–£75,000 for a dormer loft with a bedroom and en-suite, £60,000–£100,000+ for a mansard and from £25,000 for a Velux conversion; the loft conversion cost guide has the breakdown. For a Wimbledon loft we measure head height, roof structure and the stair landing first, and the quote includes structural calculations and Building Regulations approval.
Renovations and refurbishment in Wimbledon
Wimbledon refurbishments are full renovations of Victorian and Edwardian houses and flats, often including a new kitchen, bathrooms and structural openings. Typical Wimbledon refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. See our renovation cost guide for realistic budgets. Wimbledon projects are run by a single project manager under a JCT contract, with a written specification and a 10-year workmanship warranty.
