Your Local Home Extension
Specialists in Kennington
Buildaway builds extensions across Kennington and the SE11 area, working on the Georgian terraces and early Victorian townhouses, a high proportion listed or in conservation areas along Kennington Road and Cleaver Square, and on the larger plots running toward Cleaver Square. Kennington Park and Imperial War Museum are familiar territory.
Kennington rewards extending, but two things need settling early. Drainage often crosses the rear garden, and a build-over agreement takes weeks that belong at the start of a project. The second is Cleaver Square and Kennington conservation areas with frequent listed building consent, where volume limits are applied more tightly. Buildaway resolves both before design is committed. Recent extension projects in Kennington have taken in Kennington Road, Kennington Lane and the streets around the Oval cricket ground, all within the SE11 coverage area.
Buildaway combines careful design with genuine workmanship on every Kennington extension. From SE11 terraces to detached family homes, we deliver additions that feel part of the original house, backed by clear communication throughout the build.

Frequently Asked Questions
Your questions about home extensions in Kennington, answered.
How long does a rear extension take to build?
A single-storey rear extension is generally ten to fourteen weeks on site once foundations start, depending on glazing lead times. Double-storey work runs longer. Buildaway separates the design and consent period from the build period on the programme so expectations are realistic.
Do you handle drawings and building control?
Yes. Buildaway coordinates structural calculations, the building control application and inspections, and manages the party wall process where a neighbouring wall is affected, which is frequent on Kennington semi-detached properties.
Will an extension affect my neighbour?
On any semi-detached or terraced Kennington property the Party Wall Act applies and notice must be served. Buildaway handles the notices and statutory periods, and factors them into the start date rather than discovering them mid-project.
Can you extend within Cleaver Square?
Sometimes, but the tests are stricter and additions are assessed against the original dwelling rather than its current size. Buildaway will tell you honestly at survey stage whether a scheme is likely to succeed before you spend money on drawings.
What usually drives the cost up?
Groundworks and glazing. Poor ground conditions mean deeper foundations, and large glazed openings need steel. Both are established at survey in SE11, so Buildaway prices them properly rather than provisionally.
