What is Planning Permission & Do You Need It?

What is Planning Permission & Do You Need It? 〰️
Planning permission is formal consent from your local planning authority to carry out building works or change the use of a property. Getting it right from the outset is crucial — errors, poor drawings, or incorrect submissions can lead to costly delays and refusals.
Not every project requires a full planning application. Many common home improvements may fall under Permitted Development rights. This allows work to proceed without a formal application. We will assess your project and advise on the most efficient, compliant route wherever you are in the UK.
At Solid Build Architectural & Structural Engineering, we provide nationwide planning permission support, managing everything from initial feasibility, design, structural calculations and building regulations compliance. This gives you one experienced team from start to finish, not three.

Which Application do you Need?
Understanding the right type of planning application saves time and money. Our team will guide you to the most appropriate route.
-
For extensions, loft conversions, outbuildings and alterations to existing homes. The most common type for residential projects. Typically determined within 6-8 weeks.
-
Required for new builds, larger developments, and projects that fall outside Permitted Development. Allows detailed consideration of design, access, impact and more.
-
Many improvements don't require a planning application at all. We can confirm your rights via a Lawful Development Certificate (LDC) for your legal peace of mind.
-
A simplified process for specific developments (including larger home extensions and office-to-residential conversions) where the council must be notified before works begin.
-
Any works to a listed building — internal or external — require separate listed building consent in addition to planning permission. We have experience managing both.
-
If your application has been refused, we can advise on grounds for appeal and prepare a strong case to the Planning Inspectorate on your behalf.
We cover most areas in the U.K. which includes Wales, Greater London, Oxfordshire, Lancashire, the Midlands and Yorkshire.
FAQs
How long does a planning application take in Birmingham?
1
Householder applications are typically determined within 8 weeks, and full planning applications within 13 weeks. More complex or contentious applications may take longer. We track your application actively throughout to ensure no unnecessary delays.
How much does planning permission cost?
2
Birmingham City Council's planning application fee is set nationally — currently £258 for a householder application. On top of this, our professional fees vary by project scope. We provide fixed, transparent quotes so you know the total cost before we begin.
Do I need planning permission for a rear extension?
3
Not always. Single-storey rear extensions up to 4m (detached) or 3m (semi/terrace) often qualify as Permitted Development. Larger extensions may require Prior Approval or full planning permission. We'll assess your specific situation and advise the best route.
What happens if my planning application is refused?
4
A refusal isn't the end. We'll review the reasons given by the council, advise whether to appeal to the Planning Inspectorate, resubmit with revisions, or pursue an alternative approach. Many refusals are overturned on appeal when handled professionally.
Garden subdivisions and infill plots are possible in Birmingham, but require full planning permission. Key considerations include access, impact on neighbours, design quality, and garden land policies. We assess viability before you commit to the process.
Can I build a new house in my garden?
5
Do you handle structural engineering as well?
6
Yes — this is one of our key differentiators. We provide full structural design, calculations and engineering reports in-house. From steel beam specifications to foundation design, you benefit from one coordinated team from planning through to construction.
What is a Lawful Development Certificate?
7
An LDC is a formal confirmation from the council that your proposed works are lawful under Permitted Development rights. It's not legally required, but provides important protection — particularly when selling your property or securing a mortgage.
Do you work with property developers?
8
Absolutely. We regularly work with developers of all sizes on multi-unit residential schemes, HMO conversions, commercial-to-residential changes of use, and larger mixed-use developments across Birmingham and the West Midlands.
