Wrap-Around and Rear House Extensions in Sydenham

Every house extension Crest Building Services builds in Sydenham is designed around how your household really lives, not a fixed off-the-shelf package. Founder Wayne guides you from the initial site visit through design, planning and construction, applying his bricklaying specialism to the structural work that underpins the finished space.

Based in nearby Bexleyheath, Crest Building Services covers Sydenham and the wider Greater London area, including neighbouring Sundridge and Temple Mills.

What House Extensions in Sydenham Involves

Structural brickwork is handled in-house by Wayne rather than treated as a subcontracted trade, which keeps quality control consistent from the foundations up. Specialist trades such as plumbing and electrics are carried out by a network of subcontractors we have worked with repeatedly, so the finishing standard stays reliable across the whole build.

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.

Based in Bexleyheath and covering Sydenham within roughly a ten mile radius, we keep site visits and follow-ups quick rather than a logistical headache. Contact Crest Building Services with your postcode and a brief idea of what you have in mind, and we will confirm coverage and book an initial visit to talk it through in person.
