Granny Annexe Planning Permission in Hurstpierpoint

Granny Annexe Planning Permission In Hurstpierpoint, Explained Properly

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

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