rcbGroup projectHouse Extensions in Lambeth — what to expect
Lambeth extensions are mostly rear additions on Victorian terraces in SW9 and SE11. Conservation areas around Stockwell, Kennington and parts of Brixton restrict permitted development. The quality expected in this market is high — Lambeth buyers invest seriously in their properties.
Lambeth property types
Victorian terraces, Georgian townhouses near Waterloo, post-war estates, converted flats. The property type affects which extension approach works best — we'll advise from the first call.
Common extension projects we deliver in Lambeth
How we deliver extension projects in Lambeth
Project review & site visit
We look at your Lambeth property and any drawings you have, explain what's possible, the likely planning and Building Regulations route, and the risks — before you commit to anything. No obligation.
Design & planning support
We work alongside your architect or our preferred design partners to develop drawings that are buildable, compliant, and cost-effective. We flag planning and permitted development options early.
Itemised scope and price
You receive a detailed, itemised scope of works and an agreed price before we start, with exclusions and provisional sums shown. Variations are agreed in writing before any additional work begins.
Managed delivery
We coordinate trades, procurement and site logistics, with a single point of contact throughout — working to the requirements of London Borough of Lambeth and Building Control.
Sign-off & handover
We coordinate the Building Control inspections needed for sign-off, then hand over your project documents — completion certificate, guarantees and manuals as applicable — with snagging and aftercare as set out in your contract.
Planning in Lambeth
Lambeth has extensive conservation areas including Brixton, Stockwell, Kennington and Clapham. Many extensions and loft conversions require full planning applications rather than permitted development. Always verify with LBLambeth Planning.
