Do I Need Planning Permission for a Garage Conversion?
Thinking about converting your garage into a new living space?
Whether you're planning a cozy home office, an extra bedroom, or even a granny annexe, understanding planning permission requirements is an essential first step. At Sandhouse Garage Conversions, we’ve put together this handy guide to help you navigate the rules and make your project a success.
1
What Is Permitted Development?
Many garage conversions fall under Permitted Development (PD) rights, meaning no formal planning application is required. However, there are some exceptions:
• Designated Areas: If your property is in a Conservation Area or Area of Outstanding Natural Beauty, you’ll need planning permission.
• Listed Buildings: You must apply for Listed Building Consent before starting any work.
• Property Restrictions: Some properties, especially in new housing developments, have conditions requiring the garage to remain as parking space.
💡 Pro Tip: Apply for a Lawful Development Certificate to confirm your project complies with planning laws, even if it's under Permitted Development. The benefit of using Sandhouse Garage Conversions, is you won't need to worry about it, we will sort this and all other applications for you!

Do I Need Planning Permission to Build a Garage?
If you're planning to build a garage, the rules are stricter than for converting one.
• Detached Garages: A new structure may require planning permission, especially if it exceeds height limits or occupies a large footprint.
• Integral Garages: Often, these fall under Permitted Development if they don’t significantly alter your home’s exterior.

Yes, in many cases. Detached garages often require planning permission, particularly if you’re adding windows, raising the roof, or changing its use entirely.

The size of your garage can affect what permissions you need. Larger garages, or those that will house multiple living areas, may require more extensive approvals.

Other Considerations
While planning permission may not be required, building regulations always apply to ensure the safety and comfort of your conversion. These include:
• Insulation and Soundproofing
• Fire Safety
• Plumbing, Heating, and Electrics
