The Broxbourne Granny Annexe Planning Position

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

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

Granny Annexe Planning Permission FAQs for Broxbourne

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

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 Broxbourne.

What is the Caravan Act route for a Broxbourne 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, Broxbourne annexes meeting this can often avoid planning permission if they stay ancillary to the house.

Can I use permitted development for a Broxbourne annexe?

Only if it stays genuinely incidental to the house, Broxbourne 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 Broxbourne?

A Broxbourne 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 Broxbourne annexe?

We recommend it, even where your Broxbourne 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 Broxbourne annexe?

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