What planning rules in Blaby catch homeowners out?

Most homeowners in Blaby assume that standard home improvements — a loft conversion, a rear extension, a new outbuilding — fall neatly under permitted development and don't need planning permission. Sometimes that's true. But the gap between 'probably fine' and 'actually fine' is where expensive mistakes happen. WhatCanIBuild exists precisely to close that gap before you start spending money.

Conservation areas don't affect everyone equally

Blaby District has 11 conservation areas, and if your property falls within one, work that would be perfectly acceptable on the next street might require a full planning application. But here's what most homeowners don't realise: being outside a conservation area doesn't mean you're unaffected. Properties on the boundary, or with gardens that back onto one, can face complications that catch people completely off guard.

And even within a conservation area, the rules aren't uniform. What matters is your specific property, its position, and the nature of the work. The best way to understand what applies to your address — not just your postcode — is to check at the property level.

Listed buildings are a category of their own

With 196 listed buildings recorded across Blaby, there's a reasonable chance your property — or one nearby — carries listed status. If yours does, permitted development rights largely disappear. We're not just talking about major structural work. Even internal alterations, changes to windows, or modifications to outbuildings can require Listed Building Consent.

What's particularly dangerous is that buyers and homeowners often don't know their building is listed, or they assume Grade II status means lighter-touch rules than it actually does. The consequences of getting it wrong go beyond a refused application.

Article 4 directions are the hidden tripwire

This is the one that catches people most off guard. Blaby District Council, like many local authorities, can issue Article 4 directions that remove permitted development rights from specific areas — sometimes entire streets, sometimes individual properties. There's no obvious sign on your house to tell you this applies. You might be planning an extension that would be completely fine three doors down, but requires a full application at your address.

The existence of an Article 4 direction isn't something most homeowners would think to check. And not checking is exactly how a £548 planning application fee becomes the least of your problems.

What your neighbours' approvals don't tell you

A common mistake: someone on your street got permission for a side extension, so you assume yours will be approved too. But planning decisions are made on individual circumstances. Your property might have a different constraint, a different boundary relationship, or sit in a slightly different zone. What happened at number 14 is genuinely not a reliable guide to what will happen at number 22.

WhatCanIBuild shows you what's actually been approved and refused near your address — and critically, why — so you're not making decisions based on assumptions about what worked for your neighbour.

Blaby's planning landscape is more layered than it appears. The right answer to whether your project needs permission isn't a general rule — it's specific to your property, your street, and your project type. Before you commit to architects, builders, or anything else, WhatCanIBuild gives you a clear picture of where you actually stand.
