Create substantial extra space across two floors with a double storey extension.
Double storey extensions that feel original
A double storey extension can be one of the best ways to add meaningful space without sacrificing too much garden. By extending both ground and first floor, you can create larger living areas and additional bedrooms in one coordinated build.
We help you plan proportions, rooflines and window placement so the extension sits naturally with the existing house—especially important across Elmbridge's varied stock of semis, detached homes and period properties.
Because structure and services are more complex, we coordinate Building Regulations early and provide clear build sequencing to keep disruption under control. If you are exploring your options, you can request a fixed-price quotation or browse recent work in our projects gallery.

Our approach
We start with a measured survey and feasibility review, then develop a buildable scheme with clear options. Once agreed, we confirm scope and programme and move into technical detailing and approvals.
On site, we manage structure, weatherproofing and finishes with quality checks at every stage—so your extension is delivered to a standard you’ll feel proud of.
We work across East Molesey, West Molesey, Hampton Court, Kingston upon Thames, Esher, Surbiton, Elmbridge and surrounding Surrey & South West London.
