Single and Double Storey House Extensions in Kennington

Thinking about a house extension in Kennington? The right one adds space where you need it most and reads as a natural part of the original house rather than an obvious bolt-on. Crest Building Services plans, builds and project-manages the whole job, with founder Wayne on site personally for the structural work throughout.

Kennington is one of the many Greater London areas we serve, together with neighbouring Knightsbridge and Honor Oak, all within comfortable reach of our Bexleyheath base.

What House Extensions in Kennington Involves

Timescales depend on the size and type of build. A single storey extension typically takes eight to twelve weeks from groundworks to completion, while a double storey extension usually takes twelve to eighteen weeks. Exact timing depends on the scope, the weather and how quickly design and planning decisions are finalised at the outset, all of which we talk through honestly before you commit.

A written quote covers groundworks, structural brickwork, roofing and the coordination of the subcontracted trades needed to complete the shell, such as plumbing and electrics. You get a clear breakdown at the consultation stage so you know exactly what is and is not included before agreeing to proceed, with no vague figures or hidden extras appearing later in the build.

We would rather give you an honest view on feasibility, likely costs and next steps than talk you into a build that does not suit your property. Call Crest Building Services on 07495 434230 or use the quote form, and we will visit your Kennington home, take measurements and set out a clear, written plan for your extension.
