Granny Annexe Planning Permission in
Coseley

Coseley families often assume a granny annexe automatically needs full planning permission, in reality a structure that qualifies as a caravan under the 1968 Act, or a genuinely incidental outbuilding, can sometimes avoid that route entirely. We establish which applies to your specific Coseley project.

What Coseley Families Need To Know About Annexes

Three routes exist for a Coseley granny annexe, and which one applies depends on genuine facts about the structure, not assumptions. The Caravan Sites Act 1968 defines a caravan by size, 20 metres by 6.8 metres, 3.05 metres internal height, and mobility, capable of being moved by road in one or two sections.

Class E permitted development covers incidental outbuildings in Coseley, but excludes anything used as separate, self-contained living accommodation, the introduction of sleeping facilities used independently changes everything.

Where your Coseley annexe doesn’t fit either of the simpler routes, a full planning application is the honest answer, and we confirm this properly rather than guess.

We start every Coseley annexe project by establishing the real starting point, a mobile structure within Caravan Act limits, an incidental outbuilding, or genuine independent living space, since that single distinction shapes everything that follows.

Your Coseley application or certificate, whichever applies, is built around what your local council specifically expects to see, not a generic template.

Structural and building regulations work for Coseley annexe projects is handled properly from the outset, informed by real experience with this kind of project.

Why Coseley Families Trust Our Annexe Specialists

We coordinate structural and building regulations work for Coseley annexes properly, since getting this wrong can hold up an otherwise straightforward project. If you need help with a granny annexe, give us a call on 0330 133 5316 or fill in the form below.

Coseley Granny Annexe Questions Answered

Can I build a granny annexe in Coseley 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 Coseley, but a self-contained annexe with its own facilities used independently usually can’t.

Can my Coseley annexe qualify as a mobile home?

Yes, potentially, if your Coseley 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 Coseley?

Class E permitted development in Coseley 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 Coseley annexe need full planning permission?

Once a Coseley 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 Coseley annexe?

Yes, this is genuinely worth having for Coseley 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 Coseley properties?

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