Caravan Act, PD & Full Planning Explained

Granny Annexe Planning Permission in
Hayling Island (Hampshire)

Hayling Island families often assume a granny annexe automatically needs full planning permission, in reality a structure that qualifies as a caravan under the 1968 Act, or a genuinely incidental outbuilding, can sometimes avoid that route entirely. We establish which applies to your specific Hayling Island project.

What Hayling Island Families Need To Know About Annexes

Hayling Island 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 Hayling Island, 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 Hayling Island annexes, but only where it genuinely remains ancillary to the household, not a separate residence in its own right. A Hayling Island annexe needing full planning permission usually needs both, our Building Regulations drawings in Hayling Island service covers the technical compliance side, and our structural calculations in Hayling Island service covers the engineering detail.

Hayling Island Granny Annexe Questions Answered

Can I build a granny annexe in Hayling Island without planning permission?

Not automatically, a mobile structure meeting the Caravan Act’s size and mobility test, or a genuinely incidental outbuilding, can potentially avoid it in Hayling Island, but a self-contained annexe with its own facilities used independently usually can’t.

Can my Hayling Island annexe qualify as a mobile home?

Yes, potentially, if your Hayling Island 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.

Does Class E cover a granny annexe in Hayling Island?

Class E permitted development in Hayling Island 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.

When does my Hayling Island annexe need full planning permission?

Once a Hayling Island 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.

Should I get written confirmation for a Hayling Island annexe?

Yes, this is genuinely worth having for Hayling Island projects, confirming the position in writing protects you if the classification is ever questioned, especially at the point of sale.

Do you coordinate the full annexe process for Hayling Island properties?

Absolutely, Hayling Island annexe clients get the planning classification and building regulations detail handled together, not as separate, disconnected pieces of work.
