rcbGroup projectHouse Extensions in Bermondsey — what to expect
Ground floor rear extensions on Bermondsey's Victorian cottage and terrace stock can transform a compact footprint into a well-proportioned family home. Most properties on the residential streets away from the main roads have scope for rear extensions under permitted development. We also deliver structural opening work and kitchen reconfiguration as part of extension projects.
Bermondsey property types
Victorian terraces and cottages, converted warehouse and industrial buildings, modern flats, Georgian townhouses. The property type affects which extension approach works best — we'll advise from the first call.

How we deliver extension projects in Bermondsey
Project review & site visit
We look at your Bermondsey 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 Southwark 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 Bermondsey
Bermondsey falls under Southwark Council. Conservation areas in Borough and the Bermondsey Street area carry additional controls. The Old Bermondsey, Grange Road, and Bricklayers Arms conservation areas should be checked at pre-construction. Many residential streets outside these zones benefit from standard permitted development rights.
