Harborough feels like a straightforward district — market towns, villages, open countryside. But when it comes to planning permission, 'straightforward' rarely describes what's actually going on with your specific property. With 50 conservation areas and 1,286 listed buildings spread across postcodes from LE2 to LE17, the rules that apply to your neighbour's house might be completely different from the rules that apply to yours. WhatCanIBuild can cut through that uncertainty by showing you what's actually been approved and refused for properties like yours.
The short version
- Harborough has 50 conservation areas — extensive coverage that restricts external alterations across many streets
- 1,286 listed buildings recorded across the district
- Rules vary by property, not just by area — your specific combination of constraints is what matters
- A householder planning application costs £548 and typically takes 8 weeks to decide
Most homeowners assume permitted development covers them
Permitted development rights exist to let homeowners carry out certain works without a full planning application. That much is commonly known. What most people don't realise is how quickly those rights can be taken away — or restricted — without any obvious sign. Article 4 Directions can remove permitted development rights on specific streets or across whole areas. If your property sits within one, works you assumed were fine might actually require permission. Do you know whether your street is affected?
Conservation areas change everything — but differently for every property
Harborough has fifty conservation areas. That's not a small footnote — that's extensive coverage across the district's towns and villages. Being inside a conservation area doesn't just mean your house looks pretty. It means a different set of rules applies to things like roofing materials, windows, doors, outbuildings, and even certain types of cladding or rendering. But here's what trips people up: being in a conservation area and knowing what that means for your specific project are two very different things. The restrictions aren't uniform, and what was approved on one side of the street may not be approved on the other.
Listed Buildings
If your property is one of Harborough's 1,286 listed buildings — or even if it's close to one — the rules are more complex still. Listed building consent is separate from planning permission entirely, and most homeowners don't realise they need it until it's too late.
The gap between 'probably fine' and 'definitely fine'
There's a common pattern: a homeowner looks at their neighbour's extension, assumes the same applies to them, and proceeds. Sometimes that's fine. Sometimes it results in an enforcement notice. The difference usually comes down to factors they didn't know to check — flood zone designations, boundary distances, whether a previous owner already used up certain permitted development allowances, or a planning condition attached to the original planning permission that restricts future works.
None of these are things you can spot from the street.
WhatCanIBuild is the best way to understand what's actually been approved and refused for similar projects near your address — not just what the rules say in theory, but what they've meant in practice for properties on your street. That's the gap most homeowners don't know exists until something goes wrong.
What does this mean for your project?
If you're planning an extension, loft conversion, outbuilding, or any external alteration in Harborough, the honest answer to 'do I need planning permission?' is: it depends on your property. Your postcode, your street, your property's history, and the specific combination of constraints that apply to your address all feed into the answer. Getting it wrong means delays, costs, or enforcement action — none of which are worth the risk of guessing.
WhatCanIBuild reveals the approval odds for your specific project type based on what's actually happened nearby — giving you a far clearer picture than any general guide can.
