Planning permission refused. Two words that cost homeowners time, money, and momentum — and in Brighton and Hove, the reasons behind them are rarely as straightforward as people expect. With 32 conservation areas, over 1,200 listed buildings, and land bordering the South Downs National Park, there are layers of complexity here that catch even well-prepared applicants off guard. WhatCanIBuild can show you what's actually been approved and refused near your address — before you commit to anything.
The short version
- Brighton and Hove has 32 conservation areas and 1,229 listed buildings — heritage constraints affect far more streets than most homeowners realise
- Properties near the South Downs National Park face additional restrictions that don't apply elsewhere in the city
- Most refusals come down to property-specific factors, not general rules
Heritage and character — the most invisible tripwire
Brighton and Hove's conservation areas don't just affect obvious period properties on well-known streets. They cover a huge proportion of the city, and the rules inside them are different to what applies outside. What looks like a standard extension or roof alteration elsewhere can become a contested application the moment your property sits within one.
And it's not just whether you're in a conservation area — it's about what the council considers appropriate for that specific area's character. Two properties on adjacent streets can face entirely different expectations. Most homeowners don't realise this until they're already in the process.
Design and impact on neighbours — harder to predict than you think
Refusals based on design and impact on neighbouring amenity are some of the most common across the country — and Brighton and Hove is no exception. But what constitutes an unacceptable impact isn't a simple formula. It depends on your specific plot, the orientation of your property, what's already been built nearby, and how planning officers interpret the council's local policies.
The development plan shapes every decision. Officers look at proposed use, external appearance, scale, and likely impact on the surrounding area. But what that means in practice for a mid-terrace in Hove versus a semi-detached in Hanover is genuinely different. It depends on your property — and the history of decisions made around it.
Article 4 directions and South Downs proximity — the restrictions people miss
Article 4 directions remove permitted development rights that homeowners assume they have. Brighton and Hove has them. Properties near or within the South Downs National Park boundary face a further layer of restrictions under Article 1(5) land designation. These aren't always obvious from a postcode — they can affect individual streets or even individual properties within the same road.
This is where applications quietly fail. A homeowner proceeds on the assumption that their project is permitted development, or that it's a straightforward application — and then discovers their property is subject to restrictions that change everything. The best way to understand how these constraints stack up for your specific address is to check with WhatCanIBuild, which maps what's actually been happening on your street.
Don't assume approval because your neighbour got it
Planning decisions are made on individual merits. A refusal or approval next door doesn't predict your outcome — the officer, the policy context, and the specific proposal all matter.
Why refusal reasons are hard to generalise
The honest answer to this article's question is: it depends on your property. Refusals in Brighton and Hove are driven by a combination of local policy, heritage sensitivity, individual site characteristics, and how similar applications have been decided nearby. None of those things are visible from a general guide.
What WhatCanIBuild reveals is the hard stuff — approval odds for your specific project type in your area, what's been refused nearby and why, and how your property's particular combination of constraints affects your chances. That's the information that actually matters before you spend £548 on a fee.
