How to Build a Conservatory in a Conservation Area

Building a conservatory can be a great way to expand and add value to your home. But before you get started, you need to make sure that you’re following any relevant legislation.

If you’re planning to build a conservatory in a conservation area, there are a number of regulations you need to be aware of.

Read on to find out more about conservation areas, and how to build your conservatory in one.

What’s a conservation area?

A conservation area is an area of architectural or historic interest that is protected by law. There are lots of different types of conservation area. These include:

  • The centres of historic towns and cities
  • 18th and 19th-century suburbs
  • Country houses in historic parks
  • Fishing and mining villages

Local authorities protect these areas by limiting property alteration, tree felling and demolition work in them.

Can I build a conservatory in a conservation area?

conservatory or extensionYou can build a conservatory in a conservation area. You can even do it without planning permission, but you do need to follow a number of regulations. These include:

  • Not building your conservatory on the side of your property
  • Ensuring your conservatory extends no further than 4 metres away from the rear wall of your house if it’s detached, or 3 metres away if it’s attached

Planning guidelines say that you need to apply for planning permission if you’re building an extension on a property in a conservation area, and you want it to be more than one story. You also need to apply for planning permission if you want to put exterior cladding on your extension.

Conservatories are single story and don’t need exterior cladding. So if you want to build an extension in a conservation area, but don’t want to apply for planning permission, a conservatory is a good choice.
Of course you can always apply for planning permission if you do want to build a conservatory on the side of your property, or further away from your rear wall. But you’ll have to wait for permission to be granted before you start work.

Even if you think your conservatory doesn’t need planning permission, we recommend that you speak to your local planning authority before you begin building. This is because conservation area regulations can vary between different planning authorities and change over time.

How do I contact my local planning authority or apply for planning permission?
