In this post, we will look at the subject of a change of use on an existing outbuilding.
For a number of reasons, more and more people are looking to convert outbuildings into residential annexes.
An annexe can add value to a property. The value is cited to be between 20 – 30% according to multiple online resources.
What is an Annexe?
An annexe is an additional living space that is usually attached or adjacent to a main dwelling.
The main benefit of an annexe is obviously the additional living space they provide. There are many reasons that you may find yourself with the requirement for an annexe.
These reasons include:
- To provide lower cost accommodation for elderly relatives that offers independence along with the ability to offer help quickly when needed.
- To provide more space for grown-up children who require more independence and living space but who do not have the means to purchase or rent a property.
- The change of use of an existing outbuilding also offers the opportunity to generate income via letting.
Permitted Development Rules
The permitted development rules around annexes or ‘granny annexes’ are complex.
In the following excerpt from a North Somerset Council document, you will note:
Residential annexes, sometimes called a “granny annexe”, are a common form of

development that is generally proposed in order to allow relatives to live with their
family with a degree of independence. In many cases, such proposals are
considered to be acceptable by the council. However, when an annexe is proposed
outside of adopted settlement boundaries caution needs to be exercised to ensure
that this does not result in proposals which are effectively the same as creating a
new independent dwelling, which would not normally be acceptable.
To fall within permitted development the annex should share living facilities with the main residential dwelling.
Were the annexe to feature its own kitchen and bathroom, in addition to a bedroom/sitting room it would likely be considered a self-contained independent living space and require a more in-depth planning permission application.
Getting Clarity
