Can I Build A Room In My Garden?

Adding a room to your garden is a great way to create more usable space and extend the size of your home. But before you do, it’s important to consider the legal implications of building an extra room in your backyard.

Research and Consider Local Laws

Since individual municipal codes vary widely, it’s important to research local laws before you begin your project. Local municipalities generally require you to obtain a building permit before making any addition to your property. A building permit ensures that your project will comply with zoning regulations and other regulations, including ensuring the addition is designed with proper structural support and meets safety standards.

Check the Size of Your Garden

Before beginning construction, you’ll want to consider the size and shape of your garden to determine if it’s large enough to accommodate the addition. To build a room, you’ll need enough space for not only the room itself but also any additional pathways or utilities that may be needed.

Choose Your Materials Wisely

Once you’ve established the size and shape of your room, it’s time to choose the right materials. Since a garden room is often exposed to the elements, it’s important to choose materials that can withstand the exposure without deteriorating or rusting. Wood, brick, and stone are all good choices, but you’ll also want to consider the environmental impact of any materials you choose.

The answer to the question of whether you can build a room in your garden is, yes. However, before beginning your project, it’s important to research local laws and regulations, check the size of your garden, and choose your materials wisely. With proper research and planning, you can successfully create an additional room in your garden.

Can I Build a Room in My Garden?

Adding an extra room to your home provides much-needed space and privacy that can enable you to enjoy the outdoors while remaining in the comfort of your own home. But can you legally build a room in your garden?

Do I Need Planning Permission?

In most cases, you will need planning permission to build a permanent structure in your garden. Planning permission lets local authorities control the development of buildings and land in their region and ensure that it conforms with the local policy. Without planning permission, you may be subject to enforcement action.

Factors to Consider

Whether you will need planning permission depends on the type of room you want to build and its size. In general, the following factors will allow you to build a room in your garden without obtaining planning permission:

  • Size: Your room should be no larger than 4m in length, height or width.
  • Material: The room should be built from materials similar to the existing house.
  • Roof: The roof should be made from a material which is similar in appearance to the existing house.
  • Space: The room should not take up more than 50% of the garden.
  • Location: The room should not be situated any closer than 2m from the boundary of the property.
  • Distance from house: The room should not be situated any closer than 1m from the house.

What Else Should I Know?

In some cases, you may also need to apply for building regulations approval before you can start work. This will generally depend on whether the room will have any electrical, water or sewage connections.

Additionally, you may need to apply for listed building consent if the room will be situated in a building which is listed or in a conservation area.


In most cases, it is possible to legally build a room in your garden. However, you may need to apply for planning permission, building regulations approval and/or listed building consent. Ensure that you check the local policies before you start any work.
