Design & Build in Sevenoaks
Design and build is a project delivery approach where one contractor is responsible for both developing the design and constructing the project, giving the client a single point of accountability for cost, programme and quality rather than coordinating separate designers and contractors.
In Sevenoaks, that covers Riverhead, Dunton Green, Weald, Bat & Ball, Kippington. Sevenoaks is an affluent Kent town close to the Kent Downs National Landscape and extensive Green Belt land, with a historic core, well-established residential streets of substantial detached and semi-detached houses, and strong rail links into London.

Property styles in Sevenoaks
Sevenoaks has a significant stock of larger detached and semi-detached Victorian, Edwardian and interwar houses on generous plots, which frequently suit substantial rear or double-storey extensions and outbuilding conversions.
Planning considerations
Sevenoaks District Council is the local planning authority. A large proportion of the district is designated Green Belt, and parts fall within the Kent Downs National Landscape, both of which place additional constraints on new structures and extensions beyond normal permitted development limits.

FAQs
Design & Build in Sevenoaks: FAQs
Do you provide design & build across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
What is the difference between design and build and a traditional contract?
In a traditional route, you appoint an architect who designs the project and administers a separate contract with a builder. In design and build, one contractor is responsible for both the design development and the construction, giving a single point of accountability for cost and programme.
Do I still get an architect-quality design under design and build?
Yes. Design and build does not mean a lesser design service — it means the design and construction responsibility sits with one team. We work with qualified designers and, where useful, can introduce you to independent architects within the design-and-build process.
Does Green Belt designation affect extending a house in Sevenoaks?
Green Belt policy applies primarily to new buildings and significant additions that would be disproportionate to the original dwelling, rather than ruling out modest extensions. We assess this against your specific property and its planning history.
