Single and Double Storey House Extensions in Longlands

A well-planned house extension is one of the most reliable ways for homeowners in Longlands to add genuinely usable space and long-term value, without the cost and upheaval of moving. Crest Building Services designs and builds extensions of all types, with founder Wayne personally overseeing every project from the first design conversation through to final handover.

Longlands sits within our core Greater London coverage, close to London and Lower Morden, all reachable from our Bexleyheath base within roughly a ten mile radius.

What House Extensions in Longlands 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.

The process starts with a site visit to discuss your goals, budget and the practical constraints of your plot. From there we help develop workable designs and advise on planning permission and building regulations before any work begins. Once the plan is agreed, Wayne leads the groundworks and structural brickwork, with vetted subcontractors brought in for plumbing, electrics and finishing, and a final walk-through confirms every detail before handover.

Crest Building Services is founder-led, locally based and honest about what your plot can and cannot take. Every image on our site is a genuine job we have completed, not a stock photo or render.
