If you already own a home in a conservation area or are considering buying one, here’s some important advice about what improvements you can make.

A conservation area is designated as a place of architectural or historic interest. This designation means that most renovation or improvement projects will require planning permission. Planning authorities will base their decision on whether your project preserves or enhances the character of the area.

The conservation officer, your local planning committee, and the Parish Council typically make these decisions. While it is possible to build a modern home among older properties, your success will depend on how varied the styles and ages of surrounding homes are — and how your design is interpreted by the relevant committees.

Get Pre-Planning Advice

Before investing in architectural plans or drawings, visit your local planning department to get pre-application advice. It’s also wise to attend any relevant Parish Council meetings. This will give you a clearer idea of what’s likely to be accepted — and what isn’t.

Common Types of Refurbishment

Windows and Doors

If you're replacing windows or doors with ones of similar appearance, you generally won’t need planning permission. However, if you're installing a different style or material, you will need permission. Always check with your planning department first.

Extensions

In conservation areas, two-storey extensions or side extensions are not allowed. Other types of extensions, including rear single-storey extensions, may be permitted under certain conditions:

Up to 3 metres for terraced or semi-detached houses
Up to 4 metres for detached houses

All extensions should still be discussed with your planning authority.

Solar Panels

Wall-mounted solar panels require planning permission. However, roof-mounted panels can usually be installed without permission — unless local rules say otherwise. As policies change over time, it’s best to double-check with your local authority.
