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
Drainage in Sevenoaks: FAQs
Do you provide drainage across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
How do I know if I need a CCTV drain survey?
Recurring blockages, slow-draining fixtures across the property, or unexplained damp near ground level are common signs. A CCTV survey identifies the exact cause and location before any excavation is planned.
Who is responsible for a blocked shared drain?
Shared drains serving more than one property are usually the responsibility of the water company, while private drains serving a single property are the owner's responsibility. We can advise on which applies once the drain run is surveyed.
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.
