Before installing your new garden room, consider the following factors:

It’s important to select a size that fits within but does not overtake your garden. We measure up before discussing the ideal size summer house for your home.

To avoid the need for planning permission, your garden room should be below an overall height of 2.5 metres and a maximum overall size of 6m x 4m. Other factors can determine whether planning is required, such as water/ plumbing and also the location of the building within the garden.

Most garden rooms benefit from a power supply and lighting, and we can include those into your design. So you can use your outside building all year round, consider internal sockets, heating, Wi-fi and security lighting.
