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
Groundworks in Sevenoaks: FAQs
Do you provide groundworks across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
Why are groundworks often priced with provisional sums?
Ground conditions can't be fully confirmed until excavation begins — unexpected soil conditions, tree roots or buried services can affect the work. Provisional sums keep the quotation honest rather than guessing at conditions we can't yet see.
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.
