Where it is not possible to extend your property, annexes can be achieved through the use of detached garages, buildings or in some circumstances as a detached new development.

Making best use of existing buildings is always an attractive option for ancillary accommodation. It can keep build costs under control and maximise under-utilised space within your plot.

Planning legislation varies widely across local authorities who will each have unique ancillary policies.

For example:

Cornwall Council is generally in generally favour of detached annexes providing a functional link between the existing dwelling and annexe is formed, the footprint does not exceed 50% of the host dwelling and an extension is deemed unviable.North Devon & Torridge would not support detached annexes with their annexe policy stating that ‘Annexe accommodation will be physically attached to the main house and be commensurate in scale to the needs of the intended occupants.’

If it sounds complicated and subjective, unfortunately it is. Because local authorities have
differing policies it is not as simple to say that you can or can’t construct a detached annexe on your site. Because this is policy and not legislation, there will always be grey areas and inconsistencies even within a local authority.

That being said we have successfully delivered many annexes across the south west and are able to guide you through what is likely to be achievable even before any design work commences.
