Granny Annexe Planning Permission in
Coleford (Gloucestershire)

Coleford 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 Coleford project.

Granny Annexe Planning Permission In Coleford, Explained Properly

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

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

Coleford Granny Annexe Questions Answered

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

Can my Coleford annexe qualify as a mobile home?

Yes, potentially, if your Coleford 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 Coleford?

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

Once a Coleford 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 Coleford annexe?

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

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