Dartford looks straightforward on a map. But when it comes to planning, the borough has enough layers of restriction to catch out even the most prepared homeowner. What's allowed on one street can be refused on the next — and most people only find out after the work is done. WhatCanIBuild is built specifically to cut through that complexity before you start.

The short version

  • Dartford has 6 conservation areas, 370 listed buildings, and 6 Article 4 directions affecting specific streets
  • Green Belt land covers parts of the borough — and it's not always obvious which side of the line your property sits on
  • Permitted development rights sound simple, but they can be removed or restricted at the property level

Conservation areas and listed buildings aren't just someone else's problem

With 6 conservation areas and 370 listed buildings across Dartford, the chances that your property — or a neighbouring one — sits within a protected area are higher than most people assume. Living near a listed building or within a conservation area boundary can affect what you're permitted to do, even if your own house isn't listed. Most homeowners don't realise that the rules don't just apply to the building itself. The surrounding context matters too. Whether your extension, outbuilding or driveway crosses a line — sometimes literally — depends on your specific property, not a general rule.

Article 4 directions: the rule removal most people haven't heard of

Dartford has 6 Article 4 directions affecting specific streets. These are council-issued notices that remove permitted development rights that would otherwise apply to your property. That means work you'd normally be allowed to do without a planning application — certain extensions, changes to windows, alterations to the front of a property — suddenly requires full permission instead. The problem? Most homeowners have no idea an Article 4 direction exists on their street until they're already in trouble. It's not the kind of thing that comes up when you buy a house. WhatCanIBuild is the best way to find out whether your address is affected — and more importantly, what that actually means for the specific project you're planning.

Green Belt land

Parts of Dartford fall within the Green Belt. Development controls here are significantly tighter, and assumptions based on neighbouring properties outside the Green Belt can lead you seriously astray.

Permitted development isn't a free pass

Many homeowners in Dartford start a project assuming it falls under permitted development — no application needed, no fees, no waiting. But permitted development rights come with conditions, limitations, and exceptions that stack up fast. A rear extension on one property might be permitted development. The same extension on a similar property three doors down might not be — because of a conservation area boundary, a previous planning condition attached to the house, or a restriction nobody flagged at the time of purchase.

The £548 householder application fee and an 8-week decision window are painful enough. Having an application refused, or worse, being asked to undo work already completed, is far more costly. Most homeowners don't think about the refusal risk until it's too late — and by then, what's been approved and refused for similar projects nearby becomes very important information indeed.

What you actually need to know before you build

Knowing you're near a conservation area is one thing. Knowing what that means for your loft conversion, side return, or outbuilding — on your specific plot, with your specific property's planning history — is something else entirely. WhatCanIBuild shows you what's been approved and refused for similar projects on your street, how your property's combination of constraints affects your chances, and what you're actually looking at before you spend a penny.

These rules vary by property
