Kitchen Extension Cost in Brighton: 2026 Price Guide
30 Jul 2026
Brighton's identity as a Regency seaside resort, built up rapidly from the 1780s onward around the Royal Pavilion, gave the city a genuinely distinctive housing stock - elegant stucco-fronted Regency townhouses near the seafront and the Lanes, dense Victorian terraces in Hanover and North Laine further back, and later suburban housing toward Preston Park and Withdean.
| Extension size | Typical cost | Notes |
|---|---|---|
| Small (up to 15m²) | £21,000-£36,000 | Common on Hanover/North Laine terraces |
| Medium (15-25m²) | £36,000-£56,000 | Typical rear extension |
| Large (25m²+) | £56,000+ | More common in Preston Park/Withdean |
Why quotes vary so much across the city
Brighton's Regency stucco terraces, concentrated around the seafront, Kemp Town and parts of the Lanes, come with heritage expectations that a standard Victorian brick terrace in Hanover doesn't - stucco render needs specialist matching, and Brighton & Hove City Council's conservation officers expect it done well given how much of the city's Regency character depends on it. Hanover's hillside streets bring their own challenge: steep gradients that complicate access, groundworks and even scaffolding.
North Laine and parts of Kemp Town carry conservation area status reflecting Brighton's distinctive architecture, adding materials and design scrutiny to extension projects there specifically.
What's actually driving the price
- Stucco matching. Regency-era render needs specialist skills and materials that a standard brick extension doesn't require.
- Hillside access. Hanover and parts of Round Hill sit on steep streets that complicate deliveries, scaffolding and groundworks.
- Conservation status. North Laine and Kemp Town's protected status adds scrutiny of materials and design.
Frequently asked
Do I need planning permission for a rear extension in Brighton? Often not if it stays within permitted development limits, though conservation area status in North Laine and Kemp Town, and listed status on some Regency properties, can restrict this further. Check with Brighton & Hove City Council's planning portal first.
How long does a typical Brighton kitchen extension take? Around 9-13 weeks for a medium single-storey extension, longer where stucco matching or hillside access adds complexity.
