Granny Annexe Planning Permission in Ashburton

What Ashburton Families Need To Know About Annexes

Ashburton families often assume a granny annexe is either always simple or always complicated, the reality depends entirely on how it’s built and used. The Caravan Sites Act 1968 defines a caravan as a structure capable of being moved by road, within strict size limits, and a genuinely mobile annexe meeting that definition can sometimes avoid planning permission altogether.

Permitted development under Class E covers incidental outbuildings in Ashburton, subject to height and coverage limits, but not genuine self-contained living accommodation with its own bedroom, bathroom, and kitchen used independently.

We assess your specific Ashburton property and plans against all three routes honestly, rather than assuming the most complex one applies by default. A Ashburton annexe needing full planning permission usually needs both, our Building Regulations drawings in Ashburton service covers the technical compliance side, and our structural calculations in Ashburton service covers the engineering detail.

Ashburton Annexe Planning Questions Answered

What determines if my Ashburton annexe needs planning permission?

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

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 Ashburton plans genuinely meet this.

What outbuilding rules apply to a Ashburton annexe?

It depends on genuine use, an incidental Ashburton 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 Ashburton?

Genuine independence is the test in Ashburton, 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 Ashburton?

Strongly recommended for Ashburton 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 Ashburton annexe project?

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