Planning in Wandsworth — the detail

Wandsworth is one of south-west London's strongest renovation markets — the Victorian 'Tonsleys', the Heaver and Magdalen estates, the streets around Wandsworth Common and Nightingale Lane, and the villa stock of Putney and Battersea, across more than forty conservation areas from Battersea Park and Clapham Common to Wandsworth Town and Roehampton Village. Side returns, rear extensions and loft conversions are the borough's bread and butter, with a deep precedent base on the terraces.

Basements are heavily used and tightly controlled. Wandsworth Local Plan Policy LP6, Basements and Subterranean Developments, supported by the council's basement guidance, treats multi-level basements as inappropriate, expects roughly half of both front and back gardens to be retained, and looks for at least a metre of soil above the basement — with conservation-area front gardens protected more strictly. A basement impact assessment and a structural method statement are expected.

Conservation-area coverage shapes roof and elevation design across the protected estates, but much of Wandsworth's terrace stock outside them keeps permitted development rights for rear extensions and lofts — so the address-level check is what separates a prior-approval project from a full application.

Policy detail lives in the Wandsworth local plan and applications are submitted via the Wandsworth planning portal.

Article 4 directions in Wandsworth

Real · planning.data.gov.uk

No Article 4 geometry for Wandsworth appears in the national planning.data.gov.uk dataset. The borough's most significant householder control is its basement regime — Local Plan Policy LP6 (Basements and Subterranean Developments) and the council's basement guidance: multi-level basements are not supported, roughly half of front and back gardens should be retained, and at least a metre of soil above the basement is expected. Check the council's planning pages for any Article 4 directions in force.

What gets built in Wandsworth

Rear extension

The 'between the commons' terraces extend routinely; scale against the neighbour's daylight to clear the 45-degree test.

Costs & planning route →
Side return extension

Among the highest-return projects on the Wandsworth terraces; steelwork and party-wall work drive the cost.

Costs & planning route →
Loft conversion

Strong loft stock; conservation-area dormers and rooflines get the closest scrutiny.

Costs & planning route →
Basement extension

Policy LP6 treats multi-level basements as inappropriate and expects roughly half of both gardens retained, plus a metre of soil above.

Costs & planning route →
Garden room

Common across the borough's terrace gardens; the 2.5m boundary-height rule is the most-breached limit.

FAQ

Wandsworth planning, asked straight

01

Do I need planning permission for a basement in Wandsworth?

In practice, yes, and to a defined standard. Local Plan Policy LP6 (Basements and Subterranean Developments) and the council's basement guidance treat multi-level basements as inappropriate, expect roughly half of both front and back gardens to be retained and at least a metre of soil above the basement, and call for a basement impact assessment and structural method statement. Conservation-area front gardens are protected more strictly still.
02

Is my Wandsworth home in a conservation area?

It may well be — the borough has more than forty conservation areas, from Battersea Park, Clapham Common and the Heaver Estate to Wandsworth Town, Putney Embankment and Roehampton Village. Inside one, permitted development narrows and roof and elevation design are scrutinised. Enter your postcode to see the named designation, cited to source.
03

Can I do a side return or loft conversion in Wandsworth?

Very commonly. The borough's Victorian terraces are textbook side-return, rear-extension and loft stock with a deep approval record. Outside the conservation areas, many keep permitted development rights (or qualify for prior approval on larger rear extensions); inside them, expect a full application with careful roof and materials detailing. Check the address first.
04

What gets refused most often in Wandsworth?

The recurring issues are overscaled basements that breach Policy LP6's garden-retention and depth expectations, rear extensions that overshadow a neighbour against the daylight tests, and loft dormers that break a protected roofline in a conservation area. All three are visible in advance from the street's planning history and the constraint check.
05

How do I check constraints for a Wandsworth address?

Run the postcode through the Planning Permission Checker area report: it checks your coordinates against the official conservation-area geometry and shows Land Registry sold-price comparables, each cited to source. Because the borough's Article 4 position isn't in the national dataset, confirm any Article 4 direction against the council's own planning pages.
