Planning in Lambeth — the detail
Lambeth runs from the South Bank and Waterloo through Kennington and Vauxhall to the Victorian and Edwardian terrace heartland of Clapham, Brixton, Herne Hill, Streatham and West Norwood — more than sixty conservation areas in all, including Clapham, Abbeville Road, Brixton, Herne Hill, Hyde Farm and the Leigham Court Estate. The terrace belt is classic side-return, rear-extension and loft territory, and the precedent record across the Victorian stock is deep.
Lambeth applies householder Article 4 directions selectively, in specific conservation areas — Albert Square, Hyde Farm, Lansdowne Gardens, Leigham Court Estate, Park Hall Road, St Mark's, Stockwell Park and Streatham Lodge Estate among them — where they remove permitted development rights for external alterations so that even minor changes need consent. Separate directions control office-to-residential conversion in the Central Activities Zone and small-HMO conversion in parts of Streatham. The borough's Building Alterations and Extensions SPD sets its detailed design expectations.
Outside the Article 4 conservation areas, much of Lambeth's terrace stock keeps permitted development rights for rear extensions and lofts, so the address-level check is decisive — two neighbours on the same street can face different consent routes. Flats, common across the borough, have no permitted development rights and need a licence to alter.
Policy detail lives in the Lambeth local plan and applications are submitted via the Lambeth planning portal.
