Single and Double Storey House Extensions in Marylebone

A well-planned house extension is one of the most reliable ways for homeowners in Marylebone 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.

As a Bexleyheath based firm, we cover Marylebone alongside nearby Greater London areas like Mayfair and Mabley Green, which keeps visits and follow ups straightforward.

What House Extensions in Marylebone 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.

Brick matching is one of the details Wayne pays closest attention to as a bricklaying specialist. Wherever possible we source matching or closely complementary brick types so the extension reads as part of the original house rather than an obvious later addition, a difference that protects both the look and the resale value of your property.

With brick laying as Wayne's own specialism and a trusted network of trades behind him, your extension in Marylebone is built by people who take the structural work personally.
