Can I build a granny annexe in Buckingham 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 Buckingham, but a self-contained annexe with its own facilities used independently usually can’t.
Can my Buckingham annexe qualify as a mobile home?
Yes, potentially, if your Buckingham 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 Buckingham?
Class E permitted development in Buckingham 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 Buckingham annexe need full planning permission?
Once a Buckingham 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 Buckingham annexe?
Yes, this is genuinely worth having for Buckingham 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 Buckingham properties?
Absolutely, Buckingham annexe clients get the planning classification and building regulations detail handled together, not as separate, disconnected pieces of work.
