What local planning policy applies to a basement under garden in Lambeth?

Conservation areas covering Lambeth: Lambeth Council runs 64, and Clapham Common, Herne Hill, Brixton Road are the ones Lambeth owners meet most. A basement under garden inside a Lambeth conservation area loses permitted development, so the Lambeth submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Kennington a basement under garden is judged on the street elevation first.

Lambeth and Article 4: Borough-wide Article 4 for HMO conversions; plus office-to-residential restrictions. A basement under garden planned at a SE11 address is checked against that direction first; Lambeth Council publishes the Lambeth extent, and the SE11 line rarely follows the Lambeth boundary you would expect.

What Lambeth is built from: Victorian terraces in Clapham, Brixton, Herne Hill; Edwardian villas; 1930s and post-war estates in parts of Streatham; Georgian in Kennington. Mix of dense Victorian residential and post-war estate; strong conservation area coverage; generally design-led planning decisions. That mix decides the basement under garden route in Lambeth more than the postcode does.

What happens if a Lambeth property sits on a boundary?

• Westminster — cross the Lambeth boundary and Westminster City Council takes the basement under garden instead, applying 56 conservation areas of its own around SW1. We re-price basement under gardens at the Lambeth edge because Westminster policy and Lambeth policy rarely align on basement under garden depth.
• Southwark — cross the Lambeth boundary and Southwark Council takes the basement under garden instead, applying 43 conservation areas of its own around SE1. We re-price basement under gardens at the Lambeth edge because Southwark policy and Lambeth policy rarely align on basement under garden depth.
• Wandsworth — the Wandsworth boundary runs against Lambeth, so a basement under garden a street from Lambeth is decided by Wandsworth Council instead. Wandsworth runs 45 conservation areas across SW8 and its neighbours, which is why basement under gardens priced for Lambeth are re-checked against Wandsworth policy whenever the Lambeth address sits on that edge.
