Conversions in Brighton and Hove
A property conversion changes the use of existing space — such as a loft, garage, barn or outbuilding — into new habitable accommodation, and typically involves structural alterations, insulation upgrades, new services, and Building Regulations approval, with planning permission or listed building consent needed in some cases.
In Brighton and Hove, that covers Kemp Town, Hove, Preston Park, Hanover, Seven Dials, Fiveways, Patcham, Portslade. Brighton and Hove is known for its Regency architecture, extensive Victorian terraced housing, and later 20th-century development, all within a compact coastal city where many properties are in conservation areas and a significant number are listed.

Property styles in Brighton and Hove
Regency squares and terraces are concentrated around Brunswick, Kemp Town and the seafront, with dense Victorian terraced housing across much of the wider city, and later suburban housing further from the centre. Basement conversions, loft conversions and rear extensions are common project types on the terraced stock, subject to conservation area and party wall considerations.
Planning considerations
Brighton & Hove City Council is the local planning authority. The city has one of the highest concentrations of conservation areas of any local authority in the South East, and many properties are listed, particularly in the Regency squares. Basement work also requires careful consideration of structural and drainage issues in a dense urban setting.

FAQs
Conversions in Brighton and Hove: FAQs
Do you provide conversions across all of Brighton and Hove?
Yes, we cover the BN1 and BN2 and BN3 postcode areas in full, including Kemp Town, Hove, Preston Park, Hanover, Seven Dials, Fiveways, Patcham, Portslade.
Do I need planning permission for a loft conversion?
Many loft conversions fall under permitted development if they stay within volume limits and do not extend beyond the roof plane at the front. Dormers, roof terraces, and conversions on designated land or flats usually need planning permission. We confirm this at feasibility stage.
What head height do I need for a loft conversion?
As a general guide, a minimum ridge height of around 2.2 to 2.3 metres is usually needed for a workable staircase and standing space, though this varies with roof pitch and layout. We measure this on survey before advising on feasibility.
Can I extend a listed Regency property in Brighton?
Alterations to listed buildings require listed building consent in addition to any planning permission, and the historic character of Regency terraces means proposals are considered carefully. We assess feasibility on a case-by-case basis.
