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
Roof Windows in Sevenoaks: FAQs
Do you provide roof windows across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
Is "Velux" the only brand of roof window you fit?
Velux is the best-known brand and the term people commonly use for any pitched roof window, but we fit from a range of manufacturers depending on your budget and specification. We advise on the right product at survey.
Do roof windows need planning permission?
Most roof windows fall under permitted development, provided they don't project significantly beyond the roof plane and meet other standard criteria, but conservation areas and listed buildings can have additional restrictions. We confirm the position for your specific property before ordering.
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.
