Exeter feels like a straightforward city to renovate in — until you start digging into the planning rules. With 20 conservation areas, nearly 1,000 listed buildings, and layers of restrictions that vary street by street, what's allowed for your neighbour might not be allowed for you. WhatCanIBuild can cut through that uncertainty fast by showing you what's actually been approved and refused for properties like yours.
The short version
- Exeter has 20 conservation areas where extra restrictions on external alterations apply
- 995 listed buildings are recorded across the city — and being nearby one can matter too
- An Article 4 direction removes certain automatic permissions in specific areas
- What applies to your property depends on far more than just the project type
"Permitted development" isn't as simple as it sounds
Most homeowners assume there's a straightforward list of things you can do without planning permission. There is — in theory. But what most people don't realise is that those national permitted development rights can be stripped away at a local level. In Exeter, Article 4 directions do exactly that in certain areas, meaning work that would normally be permitted suddenly requires a full application. The question is whether your property sits within that zone — and that's not something you can answer by Googling the project type.
Conservation areas change the rules significantly
Exeter has 20 designated conservation areas, covering parts of the city centre, historic suburbs, and residential neighbourhoods that many homeowners wouldn't even consider "historic". If your property falls within one of these zones, even relatively minor external changes — the kind most people assume are fine — can require consent. But being in a conservation area is just the starting point. What matters is what that designation actually means for your specific project, on your specific street, with your specific property type. That's where most homeowners get caught out.
Listed Buildings
Exeter has 995 listed buildings. If your property is listed — or even shares a boundary wall or curtilage with one — the rules change substantially. Work that's straightforward elsewhere can require listed building consent on top of, or instead of, standard planning permission.
The same project can have very different outcomes on the same street
This is the part that surprises people most. Two semi-detached houses, side by side, can face different planning outcomes depending on how previous applications on the street have been decided, whether there are any local design guidelines in play, or how the council has interpreted similar cases nearby. Exeter City Council's typical decision time is 8 weeks, and a householder application costs £548 — so getting it wrong isn't just frustrating, it's expensive.
The best way to understand your real position isn't to read general guidance — it's to look at what's actually happened for similar projects near you. WhatCanIBuild shows you approval patterns and refusal reasons for your area, so you're not going in blind.
What you actually need to know before starting
General articles like this one can tell you that complexity exists. What they can't tell you is whether your extension, loft conversion, outbuilding, or boundary wall needs permission — because that depends on your address, your property's history, its designation status, and how your local planning authority has been deciding similar cases. WhatCanIBuild surfaces all of that in one place, based on your specific postcode and project.
These rules vary by property
