A genuinely self-contained Littleport granny annexe, complete with its own kitchen, bathroom, and bedroom used independently of the main house, sits outside permitted development almost universally and usually needs a full planning application.
Get Your Free Route CheckLittleport homeowners considering a granny annexe need to understand what actually changes the planning position, self-containment. An outbuilding used incidentally, for storage, a home office, or a hobby room, can be permitted development in Littleport, subject to height and coverage conditions.
Introduce a genuine bedroom, bathroom, and kitchen used independently of the main house, and that outbuilding stops being incidental, taking it outside permitted development regardless of size.
A mobile structure meeting the Caravan Sites Act 1968 definition offers a third route for Littleport annexes, but only where it genuinely remains ancillary to the household, not a separate residence in its own right. A Littleport annexe needing full planning permission usually needs both, our Building Regulations drawings in Littleport service covers the technical compliance side, and our structural calculations in Littleport service covers the engineering detail.
Caravan Act, permitted development, or full planning
Movable structures that may need no permission at all
Permitted development limits checked properly
Applications built to be approved
We begin every Littleport annexe project with an honest assessment of the actual plans, size, mobility, and intended use, before any design work begins.
Where the Caravan Act or permitted development genuinely applies to your Littleport project, we confirm that properly, usually via a Lawful Development Certificate, rather than defaulting to a full application that isn’t needed.
Where genuine self-containment means a full application is required, we build that around what Littleport’s council specifically expects to see.
We treat every Littleport annexe project as needing a genuinely honest assessment first, not a sales pitch toward the most expensive route.
Real experience with the Caravan Act, permitted development, and full application routes is what we bring to every Littleport project, not a one-size answer.
Structural and building regulations detail for Littleport annexes are handled properly from the outset, whichever route your project actually takes. If you need help with a granny annexe, give us a call on 0330 133 5316 or fill in the form below.
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 Littleport.
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, Littleport annexes meeting this can often avoid planning permission if they stay ancillary to the house.
Only if it stays genuinely incidental to the house, Littleport outbuildings under Class E permitted development cannot be separate, self-contained living accommodation, the moment sleeping facilities are used independently, permitted development stops applying.
A Littleport 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.
We recommend it, even where your Littleport annexe genuinely qualifies as a caravan or permitted development, a Lawful Development Certificate gives you written confirmation rather than an assumption that could cause problems later, particularly when selling.
Yes, we handle the full picture for Littleport annexe projects, the planning route, whichever applies, and building regulations compliance, as one coordinated service.
