FREQUENTLY ASKED QUESTIONS ABOUT GARDEN ROOMS

Do I need planning permission for a garden room?

Our garden rooms do not require planning permission in 99% of cases. If they do for any reason, there is a high chance we can install them as a mobile home. In this case, according to the law, they are not classified as buildings. Therefore they can be installed in areas where obtaining planning permission from the council is often impossible, or where permitted development rules do not apply.

How tall can the building be?

Under permitted development it could be between 2.5m and 4m depending where it will sit in your garden. If installed as a mobile home the limit is 3.05m (10 ft) between floor and ceiling. There is no restriction on the external height. Recommended height by us is 2.4m (7.87 ft) between the floor and the ceiling, as this gives a comfortable amount of room.

Will there be a problem in installing a bathroom if my garden slopes down?

No, we can install a toilet more than 100m (328 ft) away and 7m (22.96 ft) below your house. If your house is further away there are other options which will solve the issue.

Can you install a green roof?

Yes, we can, and it is a lovely feature to add. We usually advise a green roof when you can see the roof of your new building from the house.

Will I be able to fit my gym equipment, especially my treadmill?

Yes, you will. We will find a specific solution or suggest that you increase the internal height of your building to 2.4m (7.87ft) like in our standard room.
