Paying £548 and waiting eight weeks only to receive a refusal is a frustrating outcome — and it happens more than people expect in Hart. With 39 conservation areas, 47 Article 4 directions, and 1,901 listed buildings scattered across postcodes from RG27 to GU46, the district is one of the most layered planning environments in the South East. Whether your project gets approved often comes down to factors specific to your street, your property, and your precise proposal — and most homeowners don't realise that until it's too late. WhatCanIBuild can show you what's actually been approved and refused near you, so you're not going in blind.
The short version
- Hart has 39 conservation areas and 1,901 listed buildings — heritage constraints affect far more streets than most homeowners realise
- 47 Article 4 directions remove permitted development rights on specific streets, meaning work you assumed was fine may need full permission
- Refusals often come down to issues unique to your property, not just general rules
Heritage constraints catch more homeowners than you'd think
Hart's 39 conservation areas don't just cover town centres and obvious historic streets. They stretch into residential neighbourhoods in Fleet, Hook, Hartley Wintney, and beyond — areas where homeowners routinely assume the rules are straightforward. Within these areas, external alterations that would be unremarkable elsewhere become subject to far greater scrutiny. The type of materials, the style of windows, the position of an extension relative to the street — all of it matters in ways that vary from one conservation area to the next.
And then there are the 1,901 listed buildings. If your property is listed, or even if it's simply adjacent to one, the implications for your project are significant and highly specific. Most homeowners don't know what that actually means for their particular proposal until they've already submitted.
Article 4 directions — the restriction most people have never heard of
Across Hart, 47 Article 4 directions have been applied to specific streets and areas. These directions remove certain permitted development rights that homeowners would otherwise take for granted — rights that allow you to carry out work without needing to apply for planning permission at all.
The problem is that Article 4 directions are hyperlocal. Two identical houses on the same road can be in different positions relative to a direction's boundary. Whether your project needs permission, and what the council will assess it against, depends entirely on your specific address. It's not something you can judge from general guidance.
Don't assume permitted development applies
Even if a neighbour completed similar work without applying for permission, that doesn't mean the same applies to your property. Article 4 directions, conservation area boundaries, and listed building status are all address-specific.
Design, scale, and impact on neighbours
Beyond heritage and permitted development issues, Hart's planning officers regularly refuse applications on grounds that are harder to predict: the proposal is considered out of keeping with the character of the area, the scale is deemed too large relative to the original dwelling, or the impact on neighbouring amenity — overlooking, overshadowing, loss of light — is judged unacceptable.
These aren't arbitrary decisions. They're assessed against Hart's local development plan policies, and how those policies apply depends on your property's location, its existing footprint, and what's around it. A rear extension that sailed through on one street got refused two roads away. That pattern of local decisions is exactly what WhatCanIBuild surfaces — not just the constraints on your property, but what's actually happened to similar projects nearby and why.
The combination of factors is what makes it complicated
Most refusals in Hart aren't the result of one obvious problem. They happen when a property sits in a conservation area AND the proposed materials don't match local character AND the scale pushes against policy limits. It's the combination that catches people out — and the combination is different for every address.
Before you submit and pay your £548 fee, the best way to understand your actual chances is to check what's been approved and refused for projects like yours, on streets like yours. WhatCanIBuild gives you that picture — the approval odds, the nearby decisions, and the specific constraints affecting your address.
