Granny Annexe Planning Permission in
Writtle

Not every annexe in Writtle follows the same planning route. A mobile, two-section structure within strict size limits can qualify under the Caravan Sites Act, while a permanent, self-contained living space with its own bedroom and kitchen almost always needs full planning permission. We work out which one your Writtle project actually is.

Granny Annexe Planning Explained For Writtle

Writtle 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 Writtle, 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 Writtle property and plans against all three routes honestly, rather than assuming the most complex one applies by default.

How We Help in Writtle

Every Writtle 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 Writtle 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 Writtle annexe projects, whichever route applies.

Getting The Route Right For Your Writtle Annexe

Every Writtle 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 Writtle structure against the Caravan Act’s actual legal definition, rather than assuming it qualifies.

Where a Writtle 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.

Common Annexe Planning Questions in Writtle

What determines if my Writtle annexe needs planning permission?

This genuinely depends on your specific plans for Writtle, we check whether the structure is mobile, incidental, or self-contained before advising either way.

What size limits apply to a caravan-style annexe in Writtle?

The Caravan Sites Act 1968 sets the limits, 20 metres long, 6.8 metres wide, 3.05 metres internal height, and the structure must be moveable by road in one or two sections, we check whether your Writtle plans genuinely meet this.

What outbuilding rules apply to a Writtle annexe?

It depends on genuine use, an incidental Writtle outbuilding can qualify under Class E, but introducing real sleeping accommodation used independently takes it outside permitted development regardless of size.

What makes an annexe a separate dwelling in Writtle?

Genuine independence is the test in Writtle, if the annexe could function as a separate home on its own, full planning permission is almost always the realistic route.

Is a Lawful Development Certificate worth it in Writtle?

Strongly recommended for Writtle annexes, an assumption that a structure qualifies isn’t the same as formal confirmation, and a Lawful Development Certificate closes that gap.

Can you manage everything for my Writtle annexe project?

Yes, we coordinate every part of a Writtle annexe project, from establishing the correct route through to building regulations sign-off, so nothing falls through the gap.
