Storrington properties that are listed, in a conservation area, or already flats typically lose permitted development rights that would otherwise apply to a garden annexe, meaning a full application becomes the only realistic route.
Get Your Free Route CheckThree routes exist for a Storrington granny annexe, and which one applies depends on genuine facts about the structure, not assumptions. The Caravan Sites Act 1968 defines a caravan by size, 20 metres by 6.8 metres, 3.05 metres internal height, and mobility, capable of being moved by road in one or two sections.
Class E permitted development covers incidental outbuildings in Storrington, but excludes anything used as separate, self-contained living accommodation, the introduction of sleeping facilities used independently changes everything.
Where your Storrington annexe doesn’t fit either of the simpler routes, a full planning application is the honest answer, and we confirm this properly rather than guess. A Storrington annexe needing full planning permission usually needs both, our Building Regulations drawings in Storrington service covers the technical compliance side, and our structural calculations in Storrington 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 Storrington annexe enquiry starts with establishing the real facts, is the structure genuinely mobile within Caravan Act limits, is it staying incidental to the house, or is it a self-contained dwelling, since that shapes the whole route.
From there, we prepare exactly what your Storrington project needs, whether that’s a Lawful Development Certificate confirming caravan or permitted development status, or a full planning application.
Structural and building regulations input runs alongside the planning process for Storrington annexe projects, whichever route applies.
Getting the classification right for a Storrington annexe, mobile, incidental, or self-contained, matters as much as the design itself, and we treat both with equal seriousness.
Every Storrington annexe project gets an honest assessment against all three routes, not a default assumption that the most complex one applies.
We coordinate structural and building regulations work for Storrington annexes properly, since getting this wrong can hold up an otherwise straightforward project. 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 Storrington, 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 Storrington plans genuinely meet this.
It depends on genuine use, an incidental Storrington 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 Storrington, if the annexe could function as a separate home on its own, full planning permission is almost always the realistic route.
Strongly recommended for Storrington 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 Storrington annexe project, from establishing the correct route through to building regulations sign-off, so nothing falls through the gap.
