House Extension Builders in Walham Green

From modest single storey rear extensions to full double storey and wrap-around builds, Crest Building Services delivers house extensions across Walham Green that are designed to work for the way you live. Founder Wayne coordinates the structural brickwork in-house and brings in trusted, vetted trades for plumbing, electrics and finishing.

Walham Green is one of the many Greater London areas we serve, together with neighbouring Vauxhall and Walworth, all within comfortable reach of our Bexleyheath base.

What House Extensions in Walham Green Involves

We coordinate building regulations approval as part of the project and work with structural engineers where calculations are needed, such as steel beam specifications for opened-up spans. This is managed alongside the build so you are not left organising separate professionals yourself, and the finished extension is fully compliant rather than a job that struggles under scrutiny when you come to sell.

We build the full range of extension types: single and double storey extensions, side returns, rear extensions and wrap-around extensions that combine a side and rear build into one open-plan space. Wrap-arounds in particular tend to deliver more usable floor area than a rear extension alone and work well on the terraced and semi-detached homes common across the area.

Based in Bexleyheath and covering Walham Green 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.
