Granny Annexe Planning Permission in Soham

Getting The Soham Annexe Question Right First

Three routes exist for a Soham 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 Soham, but excludes anything used as separate, self-contained living accommodation, the introduction of sleeping facilities used independently changes everything.

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

What Soham Families Ask About Garden Annexes

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

Can my Soham annexe qualify as a mobile home?

Yes, potentially, if your Soham 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 Soham?

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

Once a Soham 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 Soham annexe?

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

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