Harborough feels like quiet, rural Leicestershire — market towns, villages, open countryside. Most homeowners assume that means planning is simple. It isn't. The district has 50 conservation areas and 1,286 listed buildings, and the rules that apply to your property depend on factors that aren't obvious from the outside. WhatCanIBuild is built to cut through exactly this kind of complexity.
The short version
- Harborough has 50 conservation areas — extensive coverage that catches homeowners off guard
- 1,286 listed buildings mean restrictions go far beyond what most people expect
- What's permitted on one street may require full planning permission on the next
- Your property's specific combination of constraints is what actually matters
Conservation areas are everywhere — and most homeowners underestimate them
Fifty conservation areas across a district this size means a significant portion of Harborough's housing stock sits inside one. Market Harborough, Lutterworth, Uppingham, countless villages — the heritage coverage is extensive.
Most homeowners don't realise that being inside a conservation area changes what you can do without applying for permission. External alterations that would be routine elsewhere may need consent here. The tricky part? The boundary doesn't follow obvious lines. Two houses on the same street can sit either side of it, subject to completely different rules.
And that's before you factor in whether your property has any Article 4 directions applied to it — which can strip away permitted development rights that would otherwise apply.
Listed buildings are a category of their own
1,286 listed buildings in Harborough is a significant number. If your property is listed — or even shares a curtilage with one — the restrictions extend well beyond what most people expect. Works that seem entirely minor can require listed building consent. The question of what counts as affecting the character of a listed building is genuinely complicated, and the consequences of getting it wrong are serious.
What many homeowners also miss: you don't have to live in the listed building itself for it to affect you.
Don't assume grade matters
All grades of listed building carry legal protection. A Grade II listing — the most common — still means consent is required for works that affect its special interest. "It's only Grade II" is a phrase that causes problems.
Permitted development isn't a guarantee
Harborough's mix of village properties, rural plots, and market town terraces means no two situations are the same. Permitted development rights — the works you can carry out without a full application — sound reassuring in theory. In practice, they come with conditions and limitations that depend heavily on your specific property.
Flood zones affect parts of the district. Previous extensions can eat into what you're allowed to add now. Properties converted from other uses often carry restrictions that aren't obvious. The gap between "this should be permitted development" and "this actually requires an application" is where homeowners get caught out.
This is why the best way to understand your position isn't to read the general rules — it's to check what's actually happened on your street. WhatCanIBuild shows you what's been approved and refused for similar projects nearby, and what your property's specific combination of constraints actually means for your chances.
What the rules don't tell you
Knowing you're in a conservation area is one thing. Knowing what that means for a two-storey rear extension on your specific property, on your specific street, with your specific planning history — that's something else entirely. Most homeowners go into applications without that picture.
WhatCanIBuild gives you the view that actually matters: not just the constraints, but what's been approved for projects like yours, and what the realistic odds look like before you commit to anything.
