Planning in Lambeth

Local planning rules for kitchen extensions in Lambeth.

Lambeth contains over 30 conservation areas including Brixton, Clapham Old Town, Stockwell Park, Herne Hill, Lansdowne Gardens and Tulse Hill. Article 4 directions remove permitted development rights across large parts of SW4 and SW9. The council's Local Plan and individual Conservation Area Statements govern alterations. Lambeth planners favour mansard roof extensions over rear dormers in heritage streets. Pre-application advice is recommended for any extension within a conservation area.

Our planning team handles the full submission for Lambeth addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your kitchen extension is permitted development, prior approval, or full planning before you sign anything.

Do I need planning permission for a kitchen extension in Lambeth?
