Granny Annexe Planning Explained For Kenilworth

The planning position for a Kenilworth 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 Kenilworth garden without full planning permission, provided it stays ancillary.

Where a Kenilworth 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 Kenilworth annexe needing full planning permission usually needs both, our Building Regulations drawings in Kenilworth service covers the technical compliance side, and our structural calculations in Kenilworth service covers the engineering detail.

How We Help in Kenilworth

Every Kenilworth 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 Kenilworth 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 Kenilworth annexe projects, whichever route applies.

Getting The Route Right For Your Kenilworth Annexe

Honesty about what your Kenilworth 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 Kenilworth annexe projects, which is exactly what most generic guidance gets wrong.

A Lawful Development Certificate, where your Kenilworth 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.

Granny Annexe Planning Permission FAQs for Kenilworth

Do I need planning permission for a granny annexe in Kenilworth?

It depends on three things, whether the structure genuinely qualifies as a caravan under the Caravan Sites Act, whether it stays incidental to the house under permitted development, or whether it’s a self-contained dwelling, which almost always needs a full application in Kenilworth.

What is the Caravan Act route for a Kenilworth annexe?

Under the Caravan Sites Act 1968, a structure qualifies as a caravan if it’s capable of being moved by road in no more than two sections, and doesn’t exceed 20 metres in length, 6.8 metres in width, or 3.05 metres in internal height, Kenilworth annexes meeting this can often avoid planning permission if they stay ancillary to the house.

Can I use permitted development for a Kenilworth annexe?

Only if it stays genuinely incidental to the house, Kenilworth outbuildings under Class E permitted development cannot be separate, self-contained living accommodation, the moment sleeping facilities are used independently, permitted development stops applying.

What counts as a self-contained annexe in Kenilworth?

A Kenilworth annexe with its own bedroom, bathroom, and kitchen, used independently of the main house rather than as shared accommodation, is generally treated as self-contained, which usually means full planning permission is needed.

Do I need a Lawful Development Certificate for my Kenilworth annexe?

We recommend it, even where your Kenilworth annexe genuinely qualifies as a caravan or permitted development, a Lawful Development Certificate gives you written confirmation rather than an assumption that could cause problems later, particularly when selling.

Can you handle planning and building regulations for my Kenilworth annexe?

Yes, we handle the full picture for Kenilworth annexe projects, the planning route, whichever applies, and building regulations compliance, as one coordinated service.
