Do I need planning permission for a granny annexe in Nailsea?
It depends on three things, whether the structure genuinely qualifies as a caravan under the Caravan Sites Act, whether it stays incidental to the house under permitted development, or whether it’s a self-contained dwelling, which almost always needs a full application in Nailsea.
What is the Caravan Act route for a Nailsea annexe?
Under the Caravan Sites Act 1968, a structure qualifies as a caravan if it’s capable of being moved by road in no more than two sections, and doesn’t exceed 20 metres in length, 6.8 metres in width, or 3.05 metres in internal height, Nailsea annexes meeting this can often avoid planning permission if they stay ancillary to the house.
Can I use permitted development for a Nailsea annexe?
Only if it stays genuinely incidental to the house, Nailsea outbuildings under Class E permitted development cannot be separate, self-contained living accommodation, the moment sleeping facilities are used independently, permitted development stops applying.
What counts as a self-contained annexe in Nailsea?
A Nailsea annexe with its own bedroom, bathroom, and kitchen, used independently of the main house rather than as shared accommodation, is generally treated as self-contained, which usually means full planning permission is needed.
