The Three Routes For A Norwich Granny Annexe

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

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

How We Help in Norwich

Every Norwich 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 Norwich 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 Norwich annexe projects, whichever route applies.

The Real Requirements For Norwich Granny Annexes

Getting the classification right for a Norwich annexe, mobile, incidental, or self-contained, matters as much as the design itself, and we treat both with equal seriousness.

Every Norwich annexe project gets an honest assessment against all three routes, not a default assumption that the most complex one applies.

We coordinate structural and building regulations work for Norwich 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.

Granny Annexe Planning Permission FAQs for Norwich

Do I need planning permission for a granny annexe in Norwich?

It depends on three things, whether the structure genuinely qualifies as a caravan under the Caravan Sites Act, whether it stays incidental to the house under permitted development, or whether it’s a self-contained dwelling, which almost always needs a full application in Norwich.

What is the Caravan Act route for a Norwich annexe?

Under the Caravan Sites Act 1968, a structure qualifies as a caravan if it’s capable of being moved by road in no more than two sections, and doesn’t exceed 20 metres in length, 6.8 metres in width, or 3.05 metres in internal height, Norwich annexes meeting this can often avoid planning permission if they stay ancillary to the house.

Can I use permitted development for a Norwich annexe?

Only if it stays genuinely incidental to the house, Norwich outbuildings under Class E permitted development cannot be separate, self-contained living accommodation, the moment sleeping facilities are used independently, permitted development stops applying.

What counts as a self-contained annexe in Norwich?

A Norwich annexe with its own bedroom, bathroom, and kitchen, used independently of the main house rather than as shared accommodation, is generally treated as self-contained, which usually means full planning permission is needed.

Do I need a Lawful Development Certificate for my Norwich annexe?

We recommend it, even where your Norwich annexe genuinely qualifies as a caravan or permitted development, a Lawful Development Certificate gives you written confirmation rather than an assumption that could cause problems later, particularly when selling.

Can you handle planning and building regulations for my Norwich annexe?

Yes, we handle the full picture for Norwich annexe projects, the planning route, whichever applies, and building regulations compliance, as one coordinated service.
