Granny Annexe Planning Explained For Salisbury

Salisbury 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 Salisbury, 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 Salisbury annexes, but only where it genuinely remains ancillary to the household, not a separate residence in its own right. A Salisbury annexe needing full planning permission usually needs both, our Building Regulations drawings in Salisbury service covers the technical compliance side, and our structural calculations in Salisbury service covers the engineering detail.

How We Help in Salisbury

Every Salisbury annexe enquiry starts with establishing the real facts, is the structure genuinely mobile within Caravan Act limits, is it staying incidental to the house, or is it a self-contained dwelling, since that shapes the whole route.

From there, we prepare exactly what your Salisbury project needs, whether that’s a Lawful Development Certificate confirming caravan or permitted development status, or a full planning application.

Structural and building regulations input runs alongside the planning process for Salisbury annexe projects, whichever route applies.

Getting The Route Right For Your Salisbury Annexe

We treat every Salisbury annexe project as needing a genuinely honest assessment first, not a sales pitch toward the most expensive route.

Real experience with the Caravan Act, permitted development, and full application routes is what we bring to every Salisbury project, not a one-size answer.

What Salisbury Families Ask About Garden Annexes

Can I build a granny annexe in Salisbury without planning permission?

Not automatically, a mobile structure meeting the Caravan Act’s size and mobility test, or a genuinely incidental outbuilding, can potentially avoid it in Salisbury, but a self-contained annexe with its own facilities used independently usually can’t.

Can my Salisbury annexe qualify as a mobile home?

Yes, potentially, if your Salisbury annexe meets the legal size limits, 20 metres by 6.8 metres by 3.05 metres internal height, and is genuinely capable of being moved by road, it may qualify as a caravan under the 1968 Act.

Does Class E cover a granny annexe in Salisbury?

Class E permitted development in Salisbury covers incidental structures like a home office or gym, subject to height and coverage limits, but not genuine independent living accommodation with its own bedroom, bathroom, and kitchen.

When does my Salisbury annexe need full planning permission?

Once a Salisbury structure functions as independent living space, its own facilities, used separately from the household, it’s no longer incidental, and neither permitted development nor the Caravan Act route typically applies.

Should I get written confirmation for a Salisbury annexe?

Yes, this is genuinely worth having for Salisbury projects, confirming the position in writing protects you if the classification is ever questioned, especially at the point of sale.

Do you coordinate the full annexe process for Salisbury properties?

Absolutely, Salisbury annexe clients get the planning classification and building regulations detail handled together, not as separate, disconnected pieces of work.
