Do I need planning permission in East Hampshire?

East Hampshire looks straightforward on the surface — a mix of market towns, villages, and countryside. But underneath that, there's a planning landscape that catches homeowners out constantly. Whether you need permission for your project depends less on what you're building and more on where your property sits.

The South Downs National Park changes everything

This is the one most homeowners don't realise until it's too late. A large part of East Hampshire sits within the South Downs National Park. Properties there fall under Article 1(5) land — a designation that significantly strips back the permitted development rights that homeowners elsewhere in England take for granted.

That means work you might assume is automatically allowed — certain extensions, outbuildings, roof alterations — could require a full planning application if your property is within the National Park boundary. And that boundary doesn't follow obvious lines. Two houses on the same road can be on different sides of it.

Before you assume your project is permitted development, you need to know exactly which rules apply to your specific address. WhatCanIBuild can tell you what's actually been approved and refused for properties like yours — not just what the rules say in theory.

Conservation areas and Article 4 directions

Even outside the National Park, East Hampshire has 50 conservation areas and 50 Article 4 directions across the district. These aren't just labels — they actively remove permitted development rights that would otherwise apply.

An Article 4 direction can mean that changing your windows, adding a front extension, or altering your roofline all require permission you wouldn't need elsewhere. Conservation area status adds another layer — affecting everything from the materials you use to what you can do with outbuildings and boundaries.

Most homeowners don't realise their street is affected until they're already mid-project.

Why "it's only a small project" isn't a safe assumption

The size of your project doesn't determine the complexity of the rules that apply to it. A modest single-storey extension on a property in a conservation area with an Article 4 direction in play can require full planning permission and face a completely different set of considerations than a larger project elsewhere in the district.

The £548 application fee is fixed, but the real cost of getting it wrong — having to remove or alter work after the fact — is considerably higher. East Hampshire District Council typically takes around 8 weeks to decide householder applications, and that's before any back-and-forth if there are issues.

The best way to understand what applies to your specific property — not just the general rules, but what's actually been approved and refused nearby, and what your realistic chances are — is to use WhatCanIBuild before you commit to anything.

What you actually need to know

The question isn't just "do I need planning permission?" It's whether your specific combination of constraints — National Park boundary, conservation area, Article 4 direction, listed building status, flood zone — means the usual rules don't apply to you.

That combination is different for almost every property in East Hampshire. WhatCanIBuild maps your address against all of it, and shows you what similar projects nearby actually resulted in — so you're not guessing.
