Granny Annexe Planning Permission in Hadleigh

Granny Annexe Planning Explained For Hadleigh

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

How We Help in Hadleigh

Every Hadleigh 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 Hadleigh 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 Hadleigh annexe projects, whichever route applies.

Getting The Route Right For Your Hadleigh Annexe

Every Hadleigh annexe assessment starts with an honest read on which of the three routes genuinely applies, not an assumption that defaults to the more complex, more expensive option.

We check the real mobility and size of a proposed Hadleigh structure against the Caravan Act’s actual legal definition, rather than assuming it qualifies.

Where a Hadleigh annexe genuinely needs a full application, we say so directly and build it around what the council expects to see. If you need help with a granny annexe, give us a call on 0330 133 5316 or fill in the form below.

What Hadleigh Families Ask About Garden Annexes

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

Can my Hadleigh annexe qualify as a mobile home?

Yes, potentially, if your Hadleigh 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 Hadleigh?

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

Once a Hadleigh 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 Hadleigh annexe?

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

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