Granny Annexe Planning Permission in Waterlooville

The Waterlooville Granny Annexe Planning Position

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

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

Common Annexe Planning Questions in Waterlooville

What determines if my Waterlooville annexe needs planning permission?

This genuinely depends on your specific plans for Waterlooville, we check whether the structure is mobile, incidental, or self-contained before advising either way.

What size limits apply to a caravan-style annexe in Waterlooville?

The Caravan Sites Act 1968 sets the limits, 20 metres long, 6.8 metres wide, 3.05 metres internal height, and the structure must be moveable by road in one or two sections, we check whether your Waterlooville plans genuinely meet this.

What outbuilding rules apply to a Waterlooville annexe?

It depends on genuine use, an incidental Waterlooville outbuilding can qualify under Class E, but introducing real sleeping accommodation used independently takes it outside permitted development regardless of size.

What makes an annexe a separate dwelling in Waterlooville?

Genuine independence is the test in Waterlooville, if the annexe could function as a separate home on its own, full planning permission is almost always the realistic route.

Is a Lawful Development Certificate worth it in Waterlooville?

Strongly recommended for Waterlooville annexes, an assumption that a structure qualifies isn’t the same as formal confirmation, and a Lawful Development Certificate closes that gap.

Can you manage everything for my Waterlooville annexe project?

Yes, we coordinate every part of a Waterlooville annexe project, from establishing the correct route through to building regulations sign-off, so nothing falls through the gap.
