House Extensions in Wimbledon Village (SW19)
Extending a house in Wimbledon Village? The Village sits on its hill against the Common and behaves more like a country town than a London suburb. Parkside and Marryat Road carry Victorian and Edwardian mansions of real scale, Church Road runs down toward the tennis grounds, and a conservation area covers the core, which makes the London Borough of Merton's heritage policies the first document to read on any brief. The Common itself is looked after by its own conservators, a measure of how seriously this corner of SW19 takes its setting. Our work here belongs at the top of the market: double-storey reworks, basement leisure floors and whole-house programmes. The Parkside briefs are among the largest we take anywhere, and every one is priced as a single fixed figure.
Live planning data
What earns approval on the hill
Merton treats the Village core as a special case, and the officers judge extensions on proportion, roofline and materials before anything else. That suits us. A mansion on Parkside deserves an addition drawn in its own language, not a developer standard bolted to the back, and applications built on that principle are the ones that succeed. Our luxury extensions practice was shaped by exactly this kind of street.
Houses addressing the Common face the closest reading of all, because the setting is managed by conservators as well as admired by everyone who walks it. We treat the Common frontage as part of the design brief from the first sketch, and we carry the planning file end to end so the process never lands on your desk.
No two applications are alike; the case for yours gets built before anything is submitted.
Local knowledge
The stock, corner by corner
The Common edge. The houses facing the grass hold the finest positions in SW19 and attract matching scrutiny. Rear and lower-ground schemes that leave the front elevation untouched are the natural play here.
Parkside. Mansion scale, mature plots, and briefs to suit: basement leisure floors, double-height rear additions and full reorganisations of houses that were planned for another century's way of living.
Marryat Road. Grand Victorian and Edwardian stock on wide plots with room for two-storey side and rear additions that read as part of the original composition.
Church Road. Running down toward the tennis grounds, a mix of substantial family houses where kitchen extensions and lofts join the bigger reworks, all inside the conservation core's rules. Owners here often start with one room in mind and end up rethinking the whole ground floor, which the plots readily allow.
Every street is different. That's the point.
We design to Wimbledon Village's stock and to what the council demonstrably approves — not to a template. A free site visit tells you what your house can take.

What an extension costs in Wimbledon Village in 2026
Village budgets sit above the SW19 average because the houses are larger and the finish level is set by the street. All-in construction ranges, exclusive of VAT, professional fees and the kitchen itself:
| Extension type | Typical Wimbledon Village cost | On-site time | Usual planning route |
|---|---|---|---|
| Single-storey rear | £65,000 to £130,000 | 3 to 4 months | Full application in the conservation core |
| Kitchen extension (incl. mid-range kitchen) | £80,000 to £150,000 | 3 to 4 months | As above |
| Loft conversion with dormer | £70,000 to £125,000 | 7 to 10 weeks | Usually permitted development |
| Wrap-around extension | £105,000 to £195,000 | 4 to 6 months | Full application |
| Double-storey rework | £110,000 to £235,000 | 5 to 7 months | Full application |
| Whole-house transformation | Priced on design | Phased programme | Design-led application |
Budget £3,600 to £5,700 per square metre on the hill. The luxury extension cost guide breaks down where the money goes on the larger projects. Every quote follows a free design visit and is fixed and itemised line by line.
Permissions, handled
Planning in the Village: the honest picture
The conservation area does the deciding. Inside the core, permitted development rights are curtailed and full applications are the norm. Outside it, the standard householder allowances often survive intact.
Certificates where PD holds. When a scheme can proceed under permitted development we obtain a Lawful Development Certificate, so future buyers and their solicitors see proof rather than assertion.
Decision timing. Merton's householder decisions typically arrive in about eight weeks; we build that into the programme rather than promising around it.
Party walls on tight plots. Shared boundaries and basement digs trigger the Party Wall Act. Where surveyors are appointed, £1,000 to £2,500 per neighbour is the realistic provision, and we serve and manage the notices.

Questions, answered
Wimbledon Village extension FAQs
Will Merton let me extend inside the conservation area?
In most cases yes, provided the design earns it. The designation raises the bar on proportion and materials rather than banning extensions, and a well-argued householder application is the route through.
What do Village extensions cost per square metre?
Between £3,600 and £5,700 in 2026, driven by specification. A wrap-around typically lands between £105,000 and £195,000, and double-storey reworks run £110,000 to £235,000 before VAT and fees.
Can I put a basement under a Parkside house?
The plots and values on Parkside support basement work as well as anywhere in London. It is a full-application project with structural and party wall workstreams we manage as one, priced on design.
Does the Common change what I can build?
Not legally on your own plot, but homes facing it are assessed with particular care, and the conservators' stewardship of the setting reinforces that. Schemes that respect the frontage sail more smoothly.
How fast can we get on site?
Design typically takes a few weeks, Merton's decision about eight more, then mobilisation. A kitchen extension runs three to four months of building; whole-house programmes are phased across a year or beyond.
Is the quote genuinely fixed?
Yes. After the free design visit you receive one itemised price covering the agreed scope, and changes only happen when you ask for them, costed before they start. There are no provisional sums buried in the small print and no renegotiation once the scaffolding is up.
