Do You Require Any Planning Permission For Building Garden Rooms?

Maximum Height: As we have already discussed above, the eaves should be no more than 2.5 meters. Further, the overall maximum height depends on the shape of your roof. If it is a dual pitch roof, the height can be up to 4m and for all the other roof types, the height can not exceed 3m. However, if the overall boundary of a building is about 2m, the maximum height should be kept within 2.5m.

Footprint: If your house is very old or the previous owners have already extended the house since 1948, your permitted allowance is already expired. This means you can’t build on more than 50% of land without requiring full planning permission.

Location: The room should be located at the main front of your original house. Original here means it should be built on or before July 1st,1948. No balconies and verandas will be allowed without full planning permission. Further, the height of the decks should be more than 300mm.

1.Is your property a house?

If you live in maisonettes, flats or other types of buildings, you don’t have any development rights and so you can’t build a garden room without planning permission. Moreover, if your house has undergone changes or is converted already, you might not be able to build without planning permissions.

2. Is your property contained within the listed boundaries?

If your house or building is contained within the listed boundaries, you will require a complete planning permission for making any changes to your house.

3. Is your house located in a conservation area?

If so, you can’t build a garden room without planning permission.

4. Is your house located within the national park area, world heritage site or areas of natural beauty?

If your house is situated in any of these areas, you will not be able to build a garden room without planning permission. Further, if you want to build a room more than 20m from the house, the footprints can’t exceed 10 square meters.
