Getting The Gamlingay Annexe Question Right First

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

Where a Gamlingay 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.

Granny Annexe Planning Permission FAQs for Gamlingay

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

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 Gamlingay.

What is the Caravan Act route for a Gamlingay 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, Gamlingay annexes meeting this can often avoid planning permission if they stay ancillary to the house.

Can I use permitted development for a Gamlingay annexe?

Only if it stays genuinely incidental to the house, Gamlingay 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 Gamlingay?

A Gamlingay 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 Gamlingay annexe?

We recommend it, even where your Gamlingay 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 Gamlingay annexe?

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