House Extensions in Wentworth & Virginia Water (GU25)
Own a house on the Wentworth Estate, or in Virginia Water beside it? The famous golf estate sets its own terms: mansions on pine-and-rhododendron plots arranged around the courses, long gravel drives, gatehouse privacy, and a village that exists to serve it all. Projects here occupy the top rung of our work, whole-house programmes and basement leisure floors as the natural brief, with budgets to match the setting. Consent is a layered affair: Runnymede Borough Council decides the planning application, while the Wentworth Estate's own covenants and roads committee review external works alongside it, and on the estate's fringes the green belt enters the conversation too. We design once, for every gate the scheme must pass.
Live planning data
The route to approval on the estate
A Wentworth project clears three readers before a spade turns. Runnymede assesses the planning case; the estate covenants and the roads committee consider how the work sits within the estate, from the architecture down to how construction traffic will use the private roads; and on fringe plots the green belt proportion test frames the size of the ask, ground we cover in detail in our green belt guide.
None of this is a reason to think small. Plots around the courses absorb substantial additions gracefully, and schemes drawn with the estate's character in mind, quiet massing, natural materials, landscaping that keeps the rhododendron screen intact, tend to find all three readers receptive. Designing to that standard is the core of our luxury extensions practice.
Local knowledge
The stock, from fairway to village
Around the courses. The Wentworth Estate's defining houses look over the golf itself. Work here is about adding volume without disturbing the view from either direction: single-level garden wings, basements that swallow the leisure programme, rear elevations reglazed toward the fairway.
Behind the gatehouses. Long gravel drives buy a seclusion few addresses can match, and that changes the brief: with no street to defer to, the architecture can open up dramatically at the rear while staying composed at the approach.
The pine and rhododendron plots. The estate's planting is part of its identity, so root protection and screening govern where anything can sit. We bring arboricultural advice in before concept stage rather than after.
Virginia Water village. The village serving the estate has substantial detached stock of its own, where kitchen extensions and double-storey reworks make sense at a slightly gentler budget while borrowing the same design standards.
Every street is different. That's the point.
We design to Wentworth & Virginia Water's stock and to what the council demonstrably approves — not to a template. A free site visit tells you what your house can take.

Permissions, handled
Planning in GU25: three layers, one process
The estate speaks first and last. Covenant approval and the roads committee's view on access and construction management carry as much practical weight as the permission itself. We build the logistics case into the submission from day one.
Green belt on the fringes. Where a plot touches the designation, additions are weighed against the original building. We establish that baseline early and design with margin, following the approach in the green belt guide linked above.
Permitted development, documented. Rights survive on some plots, though covenants still apply over the top. Anything delivered under PD carries a Lawful Development Certificate so the file stays clean for any future sale.
Decisions and party walls. Householder applications at Runnymede run to roughly eight weeks, handled by us from validation through to the decision notice. Party Wall appointments, when basements or boundary works trigger them, cost £1,000 to £2,500 per affected neighbour, though the estate's plot sizes often keep neighbours out of notice range.

Questions, answered
Wentworth & Virginia Water extension FAQs
Who has to approve an extension on the Wentworth Estate?
Runnymede Borough Council on the planning side, and the estate's covenants and roads committee on the estate side, which also considers how construction will use the private roads. We run all of it as one coordinated process.
What will a project cost here?
Plan on £3,800 to £6,000 per square metre in 2026. Single-storey rears typically land between £70,000 and £145,000, double-storey reworks between £125,000 and £255,000, and basements and whole-house programmes are priced on design. Quotations are fixed and itemised.
Does the green belt affect my plot?
Only on the estate's fringes. Where it applies, the extension is judged in proportion to the original building, and we confirm your baseline before drawing anything.
Are basements common at Wentworth?
They are the natural answer when a family wants a pool, spa, gym or cinema without altering the estate's outward composure. Priced on design, engineered carefully, and well suited to these plot sizes.
How does construction work on private roads?
The roads committee expects a credible plan for deliveries, parking and road protection, and we submit one with the application. Our teams work to estate rules for the entire programme.
How long should we allow overall?
Several weeks of design, roughly eight weeks for the Runnymede decision with estate approvals run alongside, then three months to a phased year on site depending on scale. Firm dates accompany the quotation.
