Planning permission in Richmond upon Thames isn't a simple yes or no — and most homeowners only discover that after they've already committed to a project. The borough has some of the most layered planning constraints in London, and what applies to your neighbour's house might not apply to yours. Tools like WhatCanIBuild exist precisely because the complexity here is genuinely difficult to navigate without knowing your property's specific situation.
The short version
- Richmond upon Thames has 72 conservation areas, substantial Green Belt, and Article 4 directions that can strip away rights you'd normally have
- The standard rules don't tell you what's actually been approved or refused on your street — and that gap can be costly
Why Richmond is different from most boroughs
Richmond upon Thames isn't a typical London borough when it comes to planning. It has 72 conservation areas — meaning a huge proportion of residential streets fall under tighter controls than homeowners often realise. Kew Gardens is a UNESCO World Heritage Site, and properties within its buffer zone face additional scrutiny that doesn't appear in any standard permitted development checklist.
Then there's the Green Belt. A significant portion of the borough sits within it, and Green Belt designation changes the picture for certain project types in ways that aren't immediately obvious from a postcode alone.
Most homeowners don't realise that even if their project is technically permitted development nationally, local conditions can override that entirely.
Article 4 directions — the rule most people miss
This is where things get genuinely complicated. Richmond Council has put Article 4 directions in place across many parts of the borough. What these do is remove permitted development rights that would otherwise apply to your home — meaning work you'd normally be allowed to do without planning permission now requires a full application.
The problem is that Article 4 directions operate at a very granular level. They can apply to a single street, a specific type of property, or even individual buildings. Two houses on the same road can be subject to entirely different rules.
If you're in an affected area and you proceed without checking, you're not just risking a refused application — you could be facing enforcement action on work that's already been done.
Conservation areas and listed buildings
If your property is in a conservation area or is listed — or is even adjacent to a listed building — the threshold for what needs permission shifts significantly. These aren't edge cases in Richmond upon Thames; they affect a substantial number of residential addresses.
The question behind the question
Even homeowners who know they're in a conservation area often don't know what that actually means for their specific project. Knowing the constraint exists is not the same as knowing how it's been applied — what's been approved, what's been refused, and why.
A householder planning application in Richmond currently costs £258, and decisions typically take around 8 weeks. But the real cost of getting it wrong isn't the fee — it's the redesign, the delay, or the enforcement notice.
The best way to understand what applies to your property isn't to read general guidance — it's to look at what's actually happened to similar projects on your street. WhatCanIBuild shows you approval patterns for your specific project type in your area, how your property's combination of constraints affects your chances, and what nearby decisions actually tell you about your own.
General rules won't tell you that. Your address will.
WhatCanIBuild takes your address and gives you a clear picture of what you're actually dealing with — not what the rules say in theory, but what they mean for your home.
