Not every annexe in Epworth 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 Epworth project actually is.
Get Your Free Route CheckEpworth 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 Epworth, 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 Epworth annexes, but only where it genuinely remains ancillary to the household, not a separate residence in its own right. A Epworth annexe needing full planning permission usually needs both, our Building Regulations drawings in Epworth service covers the technical compliance side, and our structural calculations in Epworth 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 Epworth 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 Epworth project and prepare exactly what’s needed, a Lawful Development Certificate or a full planning application.
Structural detail and building regulations compliance for Epworth annexes are handled properly throughout, not bolted on at the end.
We treat every Epworth annexe project as needing a genuinely honest assessment first, not a sales pitch toward the most expensive route.

Structural and building regulations detail for Epworth 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.
This genuinely depends on your specific plans for Epworth, 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 Epworth plans genuinely meet this.
It depends on genuine use, an incidental Epworth 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 Epworth, if the annexe could function as a separate home on its own, full planning permission is almost always the realistic route.
Strongly recommended for Epworth 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 Epworth annexe project, from establishing the correct route through to building regulations sign-off, so nothing falls through the gap.
