Do I need planning permission for a garden room in Putney?

On an unlisted whole house, usually not. Wandsworth has householder Article 4 Directions covering several conservation areas including the Dover House Estate, Putney Lower Common and Roehampton Village, but none of them withdraws the outbuilding right. They cover external alterations visible from the street, roofs, porches, hard surfacing and front boundary treatments.

Is Putney all in Wandsworth?

Putney proper is Wandsworth, but the SW15 postcode district as a whole also reaches into Kingston upon Thames and Richmond upon Thames as it extends across Putney Heath toward Kingston Vale. Worth confirming from the address rather than the postcode if you are on the far side of the Heath.

How big are gardens in Putney?

They vary by more than twofold. ONS and Ordnance Survey data puts the median private outdoor space for a house at 149.2 square metres in West Putney against 103.6 in East Putney, 71.6 around Putney Town and Wandsworth Park, and 69.5 near the Embankment. The London median is 139.6, so only West Putney sits above it.

How much does a garden room cost in Putney?

Bespoke builds typically start around £35,000. West Putney has the plot sizes to take a substantial building comfortably. Closer to the river and the station the rule limiting cover to half the curtilage becomes the design constraint.

The Estate Directions and What They Leave Alone

Putney has more Article 4 Directions than most of Wandsworth, because it contains several planned estates rather than ordinary speculative terraces. The Dover House Estate, Putney Lower Common and Roehampton Village all carry them, and the fact that they exist at all is why the estates have kept their character.

What they cover is consistent across the borough: external alterations visible from the street, roof changes, front porches, hard surfacing of front gardens, front boundary walls and gates, demolition and exterior painting. Outbuildings are not among them, on any of the three.

The Whole Borough Is Consistent Here

Wandsworth's newest direction, made for Magdalen Park in February 2023, sets out its schedule class by class and runs straight from porches to hard surfaces, skipping the outbuilding class entirely. That is not an omission in a summary, it is the sealed direction itself, and it confirms the pattern across the borough's eight householder directions.

Putney Has Few Listed Houses

The other thing that would close the route is listing, and Putney has the lightest position of the Wandsworth areas we cover. There are listed addresses on Oakhill Road, Bessborough Road, Lower Richmond Road and Putney Hill, and the Church of St Mary the Virgin, but the density is far below Clapham or Battersea. On most Putney houses the question does not arise.

West Putney and the Riverside Split

SW15 divides fairly cleanly between the Heath side and the river side, and both the plots and the tenure follow it. That split does more to determine what can be built here than any planning rule.

West Putney

37% whole houses

East Putney

26% whole houses

Smallest in SW15

ONS and Ordnance Survey median private outdoor space for a house, April 2020, and ONS Census 2021 accommodation type by ward. The London median garden is 139.6 square metres.

Only West Putney sits above the London median, and it is also the ward with the highest share of whole houses. The riverside wards are flat-dominated, and flats have no permitted development rights at all, so on that side of Putney the first question is tenure rather than design. Roehampton, at around 20 per cent whole houses, is the lowest in the area.

Garden Room Costs in Putney

Budget from around £35,000 for a bespoke build. In West Putney, on an unlisted house with a plot above the London median, projects tend to run without an application and the budget goes into the building. Nearer the river, where plots are half the size and much of the stock is flats, the honest conversation is about what will fit and whether the tenure allows it at all.

On Property Values

SW15 sold prices averaged £789,332 over the last twelve months, with terraced houses at £1,116,782 and semi-detached at £1,716,216, on Rightmove figures published 9 July 2026 covering transactions to 30 April 2026. We do not publish a percentage for what a garden room adds, because no independent body measures it.

Putney and East Putney both sit on the Zone 2 and 3 boundary, one on South Western Railway and the other on the District line. Putney Heath and Putney Lower Common are held with Wimbledon Common by Conservators under an Act of Parliament of 1871, and the Championship Course starts at Putney Embankment. The same installers cover Wimbledon, which shares those Commons, Wandsworth and Barnes across the river.
