Planning permission in Mid Devon isn't something you can second-guess based on what your neighbour got approved. With roughly 2,590 listed buildings scattered across the district, two nationally designated landscapes touching its boundaries, and Article 4 directions that quietly remove rights you thought you had, the gap between "I think this is fine" and "this has been refused" is wider than most homeowners expect. WhatCanIBuild exists precisely because that gap is hard to see from the outside.
The short version
- Mid Devon has significant heritage and landscape designations that affect thousands of properties
- Refusals often hinge on factors specific to your property — not general rules
- What got approved on your street last year may not apply to your project today
Your property might be sitting on restricted land without knowing it
Parts of eastern Mid Devon fall within the Blackdown Hills National Landscape, and a slice of the southern district touches Dartmoor National Park. Properties near or within these areas sit on what's known as Article 1(5) land — a designation that quietly strips away permitted development rights that most homeowners assume they have.
Most people don't realise this until after they've started planning. And it's not always obvious where the boundary sits. Your house could be just inside or just outside a designated area, and the planning consequences of those two positions are completely different. Whether you're in EX16, EX17, or anywhere else across the district, your postcode alone won't tell you what restrictions apply to your specific plot.
Heritage constraints trip up more applications than extensions themselves
With around 2,590 listed buildings in Mid Devon, the chances that your property — or a neighbouring one — carries heritage protections are higher than the district average for England. Listed building consent is separate from planning permission, and the rules around what you can and can't alter are far more restrictive than most homeowners anticipate.
But it's not just listed buildings. Conservation area designations affect whole streets and villages across the district, and the rules about what those designations mean for your specific project aren't written in one place. They depend on the character appraisal for your area, the council's interpretation of harm, and the specifics of your proposal — not just whether you live in a pretty village.
Heritage isn't just about old buildings
Conservation area rules apply to the setting of a property, not just its fabric. Projects that seem entirely domestic — like a new fence, a roof light, or a side extension — can fall foul of heritage policies in ways that genuinely surprise applicants.
Impact on the surrounding area is where applications quietly unravel
Mid Devon District Council, like all local planning authorities, has to weigh whether a proposal would unacceptably affect the amenities and character of the surrounding area. That sounds simple. It isn't.
Overshadowing, overlooking, loss of light, design that doesn't reflect local character — these are the reasons that appear on refusal notices again and again. And they're deeply property-specific. A two-storey extension that sailed through for a house on one side of a street might be refused for a house on the other side because of how the plots sit relative to each other.
This is where WhatCanIBuild goes beyond what you can find on a council website — it shows you what's actually been approved and refused for similar projects near your property, and what that means for your approval odds. Not generic rules. Your street. Your project type.
Don't let a £548 fee be the first time you find out
The householder application fee in Mid Devon is £548. That's before any pre-application advice, architect fees, or the cost of resubmitting if you get refused. The best way to avoid spending that money on a refusal is to understand your property's specific constraints before you apply — not after.
WhatCanIBuild shows you the full picture for your address: designation overlays, local decision history, and what similar applications near you actually achieved.
