Whether it’s a mobile annexe under the Caravan Act or a permanent structure needing full planning permission, Pulborough projects of this scale benefit from a Lawful Development Certificate confirming the position in writing, not just an assumption.
Get Your Free Route CheckPulborough 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 Pulborough, 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 Pulborough annexes, but only where it genuinely remains ancillary to the household, not a separate residence in its own right. A Pulborough annexe needing full planning permission usually needs both, our Building Regulations drawings in Pulborough service covers the technical compliance side, and our structural calculations in Pulborough service covers the engineering detail.

Not automatically, a mobile structure meeting the Caravan Act’s size and mobility test, or a genuinely incidental outbuilding, can potentially avoid it in Pulborough, but a self-contained annexe with its own facilities used independently usually can’t.
Yes, potentially, if your Pulborough annexe meets the legal size limits, 20 metres by 6.8 metres by 3.05 metres internal height, and is genuinely capable of being moved by road, it may qualify as a caravan under the 1968 Act.
Class E permitted development in Pulborough covers incidental structures like a home office or gym, subject to height and coverage limits, but not genuine independent living accommodation with its own bedroom, bathroom, and kitchen.
Once a Pulborough structure functions as independent living space, its own facilities, used separately from the household, it’s no longer incidental, and neither permitted development nor the Caravan Act route typically applies.
