Converting your garage into a usable living space is one of the most cost-effective ways to add value and functionality to your home.
Whether you want a home office, a gym, or a guest suite, a garage conversion can be a smart investment and in many cases, it does not even require full planning permission.
However, homeowners often wonder: can my neighbour stop my garage conversion under permitted development? Let’s explore what the law says, how permitted development works, and when neighbours can raise objections.
Contact usUnder UK law, homeowners have permitted development rights that allow them to make certain changes to their properties without needing to apply for full planning permission. These rights are outlined in the Town and Country Planning (General Permitted Development) (England) Order 2015, which covers a range of home improvement projects including garage conversions.
If your garage conversion meets specific criteria, you can usually proceed without a planning application. However, the project must comply with certain rules about size, use, and design to remain within permitted development.
Learn MoreIn most cases, you can convert your garage under permitted development if:
The garage is part of your main house and not a detached outbuilding.
The conversion does not enlarge the existing structure.
The external appearance remains consistent with the main dwelling.
The new space is intended for residential use only.
The property is not located in a conservation area, an Area of Outstanding Natural Beauty, or a listed building zone.
If you are unsure whether your home qualifies, your local council’s planning department, such as Bournemouth, Christchurch and Poole Council or Dorset Council, can confirm your property’s permitted development status.

Your project must comply with standards for:
Insulation and energy efficiency
Fire safety and escape routes
Ventilation and damp proofing
Structural stability and floor loadings
Electrical and plumbing work
At Coastal Property Improvements, we handle all of this for you, ensuring your conversion meets both the legal and technical requirements.

Not if it falls under permitted development. If full planning permission is required, they may submit an objection, but the council will assess it based on planning law, not personal preference.
Detached garages are considered outbuildings. You may need planning permission if you plan to convert them into living accommodation.
You could be asked to apply retrospectively or even reverse the changes if the council deems it unauthorised. Always confirm before building.

In most cases, no. As long as your project meets the permitted development criteria, you can move forward without formal planning permission. However, it is always wise to check your property’s specific restrictions and maintain open communication with neighbours to keep the process smooth.
