Quick answer
Builderr builds garden offices across Lambeth (SE1, SE5, SE11, SE24, SW2, SW4, SW9, SE27), where Victorian terraces in Brixton, Clapham and Herne Hill sit alongside 1960s estates in Stockwell and Tulse Hill. An insulated timber studio of 16–30 m² costs £18,000–£75,000; bespoke offices run to £120,000. Build programmes are 4–8 weeks. Herne Hill conservation area and the Brixton market conservation area in SE24 and SW9 remove Class E PD rights for affected properties. Many Lambeth terraces have longer-than-average rear gardens relative to their plot width, making studios straightforward to site under PD. Builderr carries out designation checks and manages Lawful Development Certificate applications for all projects.

Planning in Lambeth
Local planning rules for garden offices 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 garden office is permitted development, prior approval, or full planning before you sign anything.
