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.

What gets built in Lambeth
Clapham, Brixton and Streatham terraces are deep PD-precedent territory; conservation and the targeted Article 4 areas need a full application.
Rear extension in Lambeth →The signature project on Clapham and Brixton's Victorian terraces — the precedent base is deep.
Side return extension in Lambeth →Follow the street's roof pattern and rear dormers approve well; conservation and Article 4 areas need an application.
Loft conversion in Lambeth →Single-storey basements under the footprint can succeed; expect a full impact assessment and structural method.
Basement extension in Lambeth →The garden-office market is strong; short terrace gardens make the 50% coverage and boundary-height rules binding.

Borough-level rules only narrow it down. Enter a Lambeth postcode for the live constraint check — conservation area, Article 4 and sold-price comparables, cited to source.
Free, and it stays free — no account, no payment. The check reads official geometry at the property's own coordinates; it cannot read a lease, a listing or the condition of the building.
Who to talk to about a Lambeth property
Constraint data tells you what applies. It does not draw a scheme, argue a case with Lambeth's planners, or inspect a building. For that this site points at two separately regulated practices — which one you need depends on the job in hand.
The architect's door: designing the scheme and getting it consented — drawings, the planning application and the building-regulations package.
- Residential design for extensions, lofts, basements and conversions
- Planning applications, pre-application advice and appeals
- Lawful development certificates
- Building-regulations and technical design drawings
- Conservation-area design and listed building consent applications
The chartered-surveyor door: professional judgement on condition, risk, party wall matters and leasehold process.
- Building surveys, RICS home surveys and defect diagnosis
- Party wall matters and awards
- Technical due diligence before a purchase
- Leasehold and major-works advisory (Section 20)
- Dilapidations and building pathology
Both practices are independent and separately regulated — Hampstead Chartered Surveyors & Building Consultancy is an RICS-regulated firm (Firm Reg. 923064); Hampstead Architecture and Planning are ARB-registered architects. We publish no fees for their work: each quotes directly for the job in front of them. Your enquiry goes to the practice you choose — we never pass your details to builders or other third parties.
