Granny Annexe Planning Permission in Winchcombe

What Winchcombe Families Need To Know About Annexes

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

Where a Winchcombe 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.
