Caravan Act, PD & Full Planning Explained

Granny Annexe Planning Permission in
Fishguard

Fishguard properties that are listed, in a conservation area, or already flats typically lose permitted development rights that would otherwise apply to a garden annexe, meaning a full application becomes the only realistic route.

Granny Annexe Planning Explained For Fishguard

Fishguard homeowners considering a granny annexe need to understand what actually changes the planning position, self-containment. An outbuilding used incidentally, for storage, a home office, or a hobby room, can be permitted development in Fishguard, subject to height and coverage conditions.

Introduce a genuine bedroom, bathroom, and kitchen used independently of the main house, and that outbuilding stops being incidental, taking it outside permitted development regardless of size.

A mobile structure meeting the Caravan Sites Act 1968 definition offers a third route for Fishguard annexes, but only where it genuinely remains ancillary to the household, not a separate residence in its own right. A Fishguard annexe needing full planning permission usually needs both, our Building Regulations drawings in Fishguard service covers the technical compliance side, and our structural calculations in Fishguard service covers the engineering detail.

Common Annexe Planning Questions in Fishguard

What determines if my Fishguard annexe needs planning permission?

This genuinely depends on your specific plans for Fishguard, 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 Fishguard?

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 Fishguard plans genuinely meet this.

What outbuilding rules apply to a Fishguard annexe?

It depends on genuine use, an incidental Fishguard 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 Fishguard?

Genuine independence is the test in Fishguard, 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 Fishguard?

Strongly recommended for Fishguard 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 Fishguard annexe project?

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