Getting refused planning permission in Bromley isn't always about doing something outrageous. Plenty of straightforward-looking projects — extensions, outbuildings, loft conversions — get knocked back every year for reasons the homeowner never saw coming. The rules that apply to your neighbour's house may not apply to yours, and most people only discover that after they've already submitted. If you want to understand what applies to your specific address before you get that far, WhatCanIBuild can show you what's actually been approved and refused nearby — and why.
The short version
- Refusal reasons in Bromley often come down to property-specific constraints, not just general planning rules
- Green Belt, conservation areas, and Article 4 directions affect large parts of the borough — but not all in the same way
- What got approved on your street last year is more useful than any general guidance
The Green Belt and Metropolitan Open Land problem
Bromley has a significant amount of Green Belt and Metropolitan Open Land. If your property sits within or adjacent to one of these designations, permitted development rights — the rules that normally let you build without applying — can work very differently. Most homeowners don't realise their property is affected until the council tells them it is. And it's not just about whether you're in the Green Belt. It's about how your specific plot sits within it, what's already been built, and how the council interprets cumulative impact. Two houses on the same road can face completely different assessments.
Character, appearance, and the neighbours you can't control
One of the most common reasons applications are refused across Bromley is that the proposed development is judged to harm the character or appearance of the area. That sounds vague — because it is. It depends on your street, the style of surrounding properties, and what the council's development plan says about that particular area. Conservation areas add another layer entirely. Bromley has several, and the restrictions within them go well beyond what most people expect. The same extension that sailed through planning in Bickley could be refused in Chislehurst. Whether your project would affect the character of your area is something you can't answer from general guidance.
Article 4 directions — the restriction most people have never heard of
Article 4 directions remove permitted development rights in specific locations. They're applied street by street, sometimes even property by property. Bromley has areas where these directions are in force, which means work you'd normally be allowed to do without permission suddenly requires a full application — and can be refused. Most homeowners don't know whether their address is covered by one until it becomes a problem. This is exactly the kind of thing that WhatCanIBuild surfaces for your specific property, rather than leaving you to piece it together yourself.
Impact on neighbours and amenity
Even if your project looks fine on paper, the council will consider how it affects neighbouring properties. Overshadowing, overlooking, loss of privacy, overbearing appearance — these are all grounds for refusal, and they're assessed case by case. The height, position, and orientation of your proposed build all feed into this. So does the relationship between your property and the ones next to it. There's no universal threshold that tells you whether your extension crosses the line. It depends on your property.
Remember
Planning decisions in Bromley must be made in line with the local development plan. National guidance sets the framework, but local policies and site-specific constraints shape the actual outcome — often in ways that aren't obvious from a general search.
The best way to check before you commit
Understanding why applications get refused in Bromley in the abstract is far less useful than knowing what's been approved and refused on your street, what constraints are attached to your specific address, and how similar projects nearby have fared. That's what WhatCanIBuild is built to show you — not just the rules, but the real-world outcomes that tell you whether your project is likely to fly.
