Thinking about an annexe in a National Landscape, the Green Belt, or a Conservation Area? NAPC are experts in annexe planning permission in protected areas.
Adding an annexe to your property can be a big decision, whether it’s for elderly parents, adult children, or even a flexible workspace. But if your home is within a protected area such as a National Landscape, the Green Belt, or a Conservation Area, securing planning permission for an annexe can be more complex than in other locations.
As a specialist planning consultancy focused on annexes, we’ve helped hundreds of homeowners navigate these challenges. Here’s what you need to know if you’re considering an annexe in a protected area.
Annexes in National Landscapes (Areas of Outstanding Natural Beauty)
National Landscapes (formerly Areas of Outstanding Natural Beauty, or AONBs) are protected because of their natural beauty. Local councils are required to prioritise conserving and enhancing these landscapes, which means stricter rules for annexe planning permission.
- Challenges: Annexes must be carefully designed to minimise their impact on the wider landscape.
- What works: Traditional or locally appropriate materials, modest scale, and sensitive siting close to the main dwelling.
- Key tip: A professional planning statement and, in some cases, a landscape assessment can make a significant difference.
If you’re applying for an annexe in a National Landscape, the quality of your submission is crucial.
Annexes in the Green Belt
The Green Belt is one of the most restrictive planning designations, designed to prevent urban sprawl and protect open land. Many homeowners assume it’s impossible to get permission for an annexe in the Green Belt, but that isn’t necessarily true.
- Challenges: The main hurdle is proving that your annexe is not inappropriate development.
- What works: Annexes that are modest in size, clearly ancillary (subordinate) to the main house, and designed to avoid harming the openness of the Green Belt.
- Key tip: Demonstrating a genuine family need (for example, housing a dependent relative) can strengthen your case.
Our team has successfully secured annexe planning permission in Green Belt areas across England and Wales.
Annexes in Conservation Areas
Conservation Areas protect historic and architectural character, so councils are extra cautious about new buildings, including annexes. If you’re planning an annexe in a Conservation Area, expect close scrutiny of the design.
- Challenges: Annexes that dominate gardens or use unsympathetic modern designs often face refusal.
- What works: High-quality design that complements the host property, sensitive siting, and the use of appropriate materials.
- Key tip: A Heritage Statement is often required to show that your annexe won’t harm the area’s special character.
A carefully designed annexe can still be approved in a Conservation Area with the right planning strategy.
