Design and build

Yes. All of our Cube Garden Rooms are made to order and can be made in any size and specification you need.

Yes. A garden gym is built using the same method as a garden room, although we increase the foundation support to take the weight of the equipment. See our garden gym projects.

Yes. Planning permission is not normally required, although this depends on the size of the garden studio you want us to build. See our art studio project.

Build time varies with the size of the room and any extras, but on average a build takes around 8 days.

Yes. All of our rooms come with either a pad or a screw foundation. The ground needs to be flat, although we can carry out groundworks for an additional charge.

All of our rooms are fully completed to regulations and ready to connect to the mains. We can provide the connection for an additional cost.

Planning permission and regulations

Planning permission is not normally required, although it may be needed depending on the size and use of the garden room.

Usually not. In England a garden office counts as an outbuilding, and it can normally be built under permitted development, without planning permission, as long as:

  • it is single storey and not in front of the house
  • the eaves are no higher than 2.5 metres, and the overall height is no more than 3 metres (4 metres with a dual-pitched roof)
  • it is no more than 2.5 metres high if it is within 2 metres of a boundary
  • together with any other outbuildings and extensions, it covers no more than half the land around the original house

You will need planning permission if your home is a listed building, and extra limits apply in conservation areas and National Landscapes such as the Cotswolds. Building regulations are separate: they do not normally apply if the internal floor area is under 15 square metres, or between 15 and 30 square metres if the room is at least 1 metre from every boundary, as long as there is no sleeping accommodation. If you are unsure, check with your local council before you build.

Not usually. Adding a toilet does not on its own mean you need planning permission, as long as the garden room stays within the permitted development limits for outbuildings and is used for something incidental to your home, such as an office, gym or studio with a WC. Planning permission is likely to be needed if the room becomes separate, self-contained living accommodation, for example with a bedroom, bathroom and kitchen.

Building regulations do apply to the toilet itself. Installing a WC and new foul drainage will normally need building regulations approval, covering the plumbing, drainage and ventilation. If you are unsure, check with your local council before you build.

Yes, although you would need to apply for planning permission, because it would be used as an additional bedroom rather than as additional living space.
