Do I need planning permission for my garden office? 

That’s one of the most frequent questions we are asked.

All timber garden structures, including Garden Sheds, Summerhouses and Garages are subject to planning permission rules; however, the good news is that the majority of our buildings won’t actually require planning permission for installation.

Whether you need planning permission for your garden office (garden room, cabin etc.), or not will all depend on where you wish to place the building in your garden. Should live in an area that has been designated as a national park or similar the whole process will be more complex and complicated. Providing certain criteria are met and the building is considered permitted development, you can proceed without needing permission.

Do I need planning permission for my Garden Office

Garden Buildings are considered Permitted Development and do NOT require planning permission as long as:

The building has to be less than 2.0m from the boundary of the property. The maximum overall height can’t be more than 2.5m from existing ground level. Nevertheless, if you want a large building this close to the boundary, which, as a general rule, will have a taller roof height, we can lower the overall roof height of the majority of our apex roof buildings, and our garden buildings with pent roofs are all under 2.5m in height as well.

The building needs to be placed more than 2.0m from the boundary of the property. If this is the case, a single storey garden building can have a maximum eave height of 2.5m. This is a maximum overall height of 4.0m for a dual-pitched roof and 3.0m maximum overall height for a pent roofed building. If you would like the overall height to be taller than these roof heights, you will need to apply for planning permission.

You can not use the building as self-contained living accommodation or have an antenna*.


planning permission

No more than 50% of the area of land around the original house** should be taken up by garden buildings or other buildings.

Outbuildings should not be closer to a road or public highway than the original house** itself.

** (The term original house means the house as it was first built or as it stood as of 1 July 1948 (if it was built before this date). Any extension, even if it was completed by a previous occupier, does not constitute as the original house (unless it was in place on 1 July 1948).

You would need to apply…

If your garden building does NOT meet the above criteria, e.g. if you want a garden building taller than 2.5m and situated less than 2.0m from a boundary of your property, then you would NEED to apply for planning permission.

If, however, your garden building DOES comply with the above criteria, you won’t need to apply for planning permission. You can have a garden building up to 30m2 (internal size). Anything bigger than 30m2 will need to go through building regulations
