What planning rules in Solihull catch homeowners out?

Solihull feels like a straightforward place to extend or improve your home. Quiet streets, suburban semis, established neighbourhoods. Surely the planning rules are just as straightforward? Most homeowners think so — right up until they're not. If you're planning any work on your Solihull property, WhatCanIBuild can show you what's actually been approved on properties like yours, and what the real odds are for your specific project.

Permitted development isn't a free pass

The concept of permitted development — work you can do without a formal planning application — sounds reassuring. But most homeowners don't realise how many conditions sit underneath it. The rights that apply to a standard semi in Shirley may not apply to a property in a conservation area, a house that's been converted under a previous permitted development right, or a home affected by an Article 4 direction.

Solihull has areas where permitted development rights have been quietly restricted. If your street falls under one of those restrictions, work that looks routine from the outside could require a full application. The problem? You won't know unless you check your specific address — not just the general rules.

Green Belt land changes everything

Parts of Solihull borough sit within Green Belt. If your property backs onto or sits within Green Belt land, the planning considerations around extensions, outbuildings, and other external changes can be significantly different. Most homeowners in these areas assume they're in the same position as everyone else. They're often not.

Green Belt doesn't mean nothing can be done — but it does mean the margin for error is smaller and the scrutiny is higher. Whether your particular project would be viewed favourably by Solihull Metropolitan Borough Council is something that depends on your property's specific situation, not a general rule you can look up in a guide.

Conservation areas and Article 4 directions — does your street have one?

Solihull has conservation areas where additional restrictions apply to what you can do without permission. But here's what catches people out: even knowing you're in a conservation area isn't enough. What matters is what that designation actually means for your specific project on your specific property.

Article 4 directions layer on top of this. These are locally applied restrictions that remove permitted development rights in certain areas — often without homeowners being aware. They're not advertised on a sign outside your house. Most people only find out when it's too late.

The best way to understand what applies to your address — not just your area — is to check at the property level. WhatCanIBuild pulls together your property's specific constraints alongside what's actually been approved and refused on nearby projects, so you're not guessing based on what your neighbour told you.

The £548 question

A householder application in Solihull costs £548 and takes around 8 weeks to decide. That's before any pre-application advice — which, in Solihull, doesn't cover householder works at all. You're going in without a council safety net. Getting it wrong means delays, refusals, and potentially having to undo work already done.

The gap between "I think this is fine" and "I know this is fine" is where most homeowners get caught. WhatCanIBuild shows you not just whether constraints exist on your property, but how similar projects nearby have actually fared — the approvals, the refusals, and the reasons behind them.
