The Dunster House Introductory Guide:


Do I need Planning Permission if my garden building is at the front of my property?

Putting an outbuilding in front of the main elevation of your property (as it was originally built or as it was on 1st July 1948) will require Planning Permission.


Do I need Planning Permission if I live in a Designated Area?

Designated land includes areas of outstanding natural beauty, national parks and the Broads, world heritage sites and conservation areas.


Do I need Planning Permission for a garden building in the grounds of a Listed Building?

Listed buildings have extra restrictions and if so, you will need planning permission.


How big can my garden building be without needing Planning Permission?

A single pitched roof must have an eaves height under 2.5m and be no higher than 3m.

The majority of Dunster House garden buildings do not exceed this.

How far from a boundary can my garden building be without needing Planning Permission?

Dunster House garden buildings are almost all made to be under 2.5m high so that you don’t need to place them over 2m from your boundary.


How much of my garden can my garden building take up without needing Planning Permission?

Outbuildings cannot exceed 50% of the total land around the original house (as it was first built or as it stood on 1st July 1948).


Can I install my garden building onto a deck or decking?

If the base or deck is higher than this then you may require planning permission.


Can I put sleeping accommodation into my garden building?

Any temporary garden building must not contain permanent sleeping accommodation without planning permission.


Can I connect TV aerials to my garden building?

Attachment of microwave antennas can result in the need for planning permission.



If you are sure that your garden building will not meet with any of the requirements for planning permission, then it will be classed as ‘Permitted Development’

Dunster House products are designed for the UK market, in response to the Permitted Development rules and to help our customers avoid planning issues. Be aware of other cabin companies buying in products for the European market that are not designed for these planning rules as you could end up with a problem from your local planning authority and neighbours.


How can I be sure that I do not need planning permission for my garden building?

Just because your plans do not pass all the criteria, this doesn’t mean that you won’t be able to build. If your plans do not fulfil the permitted development criteria, it means that you will need to contact your local council and possibly apply for planning permission.

Remember that if you do need to apply for planning permission, often your neighbours will be given the opportunity to object, so talk to them first about your plans and consider how you can ensure your building or structure will cause as little inconvenience as possible.
