The Three Routes For A Wigston Granny Annexe

The planning position for a Wigston annexe comes down to two questions, is it genuinely mobile within the Caravan Act’s size limits, and is it genuinely ancillary to the house rather than a separate, independent dwelling.

A structure meeting the caravan definition, movable by road, built in no more than two sections, within 20 metres by 6.8 metres by 3.05 metres internal height, can often be sited in a Wigston garden without full planning permission, provided it stays ancillary.

Where a Wigston annexe is permanently fixed, or genuinely self-contained with its own facilities used independently, the caravan and permitted development routes generally don’t apply, and a full application becomes the realistic path. A Wigston annexe needing full planning permission usually needs both, our Building Regulations drawings in Wigston service covers the technical compliance side, and our structural calculations in Wigston service covers the engineering detail.

How We Help in Wigston

Every Wigston 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 Wigston 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 Wigston annexe projects, whichever route applies.

The Real Requirements For Wigston Granny Annexes

Honesty about what your Wigston annexe actually needs comes before any recommendation, not after we’ve quoted for the more expensive route.

We understand the genuine legal distinction between incidental and self-contained use for Wigston annexe projects, which is exactly what most generic guidance gets wrong.

A Lawful Development Certificate, where your Wigston annexe genuinely qualifies for it, gives you written confirmation rather than a risky assumption. If you need help with a granny annexe, give us a call on 0330 133 5316 or fill in the form below.

What Wigston Families Ask About Garden Annexes

Can I build a granny annexe in Wigston 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 Wigston, but a self-contained annexe with its own facilities used independently usually can’t.

Can my Wigston annexe qualify as a mobile home?

Yes, potentially, if your Wigston 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 Wigston?

Class E permitted development in Wigston 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 Wigston annexe need full planning permission?

Once a Wigston 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 Wigston annexe?

Yes, this is genuinely worth having for Wigston 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 Wigston properties?

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