Not every annexe in Leek follows the same planning route. A mobile, two-section structure within strict size limits can qualify under the Caravan Sites Act, while a permanent, self-contained living space with its own bedroom and kitchen almost always needs full planning permission. We work out which one your Leek project actually is.
Get Your Free Route CheckA granny annexe in Leek can follow three genuinely different routes. A structure that meets the legal definition of a caravan under the Caravan Sites Act 1968, capable of being moved by road in one or two sections and within maximum dimensions of 20 metres by 6.8 metres with an internal height of 3.05 metres, can often be sited without planning permission provided it remains ancillary to the house.
An outbuilding used incidentally to the enjoyment of the house, a home office, gym, or storage, can fall under Class E permitted development, but the moment it includes genuine sleeping accommodation used independently, it’s no longer considered incidental, and permitted development stops applying.
Where neither route fits, a full planning application is the reality for Leek properties, and we confirm this honestly rather than assume. A Leek annexe needing full planning permission usually needs both, our Building Regulations drawings in Leek service covers the technical compliance side, and our structural calculations in Leek 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
Every Leek annexe enquiry starts with the same honest question, mobile caravan, incidental outbuilding, or genuine separate dwelling, since the answer determines everything that follows.
From there, we confirm the correct route for your Leek project and prepare exactly what’s needed, a Lawful Development Certificate or a full planning application.
Structural detail and building regulations compliance for Leek annexes are handled properly throughout, not bolted on at the end.
We tell Leek families honestly whether their annexe genuinely qualifies for the Caravan Act or permitted development routes, rather than defaulting every enquiry to a full application.
Getting the self-containment question right matters more than almost anything else for a Leek annexe, and we assess this honestly rather than assume either way.
Structural and building regulations detail is built into every Leek annexe project from the start, whichever planning route applies. If you need help with a granny annexe, give us a call on 0330 133 5316 or fill in the form below.
This genuinely depends on your specific plans for Leek, we check whether the structure is mobile, incidental, or self-contained before advising either way.
The Caravan Sites Act 1968 sets the limits, 20 metres long, 6.8 metres wide, 3.05 metres internal height, and the structure must be moveable by road in one or two sections, we check whether your Leek plans genuinely meet this.
It depends on genuine use, an incidental Leek outbuilding can qualify under Class E, but introducing real sleeping accommodation used independently takes it outside permitted development regardless of size.
Genuine independence is the test in Leek, if the annexe could function as a separate home on its own, full planning permission is almost always the realistic route.
Strongly recommended for Leek annexes, an assumption that a structure qualifies isn’t the same as formal confirmation, and a Lawful Development Certificate closes that gap.
Yes, we coordinate every part of a Leek annexe project, from establishing the correct route through to building regulations sign-off, so nothing falls through the gap.
