Getting the Neyland annexe classification right from the start, mobile home, incidental outbuilding, or genuine dwelling, shapes the entire project timeline and cost. We establish this honestly before any design work begins.
Get Your Free Route CheckNeyland 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 Neyland, 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 Neyland property and plans against all three routes honestly, rather than assuming the most complex one applies by default. A Neyland annexe needing full planning permission usually needs both, our Building Regulations drawings in Neyland service covers the technical compliance side, and our structural calculations in Neyland service covers the engineering detail.
Caravan Act, permitted development, or full planning
Movable structures that may need no permission at all
Permitted development limits checked properly
Applications built to be approved
Every Neyland annexe enquiry starts with the same honest question, mobile caravan, incidental outbuilding, or genuine separate dwelling, since the answer determines everything that follows.
From there, we confirm the correct route for your Neyland project and prepare exactly what’s needed, a Lawful Development Certificate or a full planning application.
Structural detail and building regulations compliance for Neyland annexes are handled properly throughout, not bolted on at the end.
Every Neyland 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 Neyland structure against the Caravan Act’s actual legal definition, rather than assuming it qualifies.
Where a Neyland 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.
Not automatically, a mobile structure meeting the Caravan Act’s size and mobility test, or a genuinely incidental outbuilding, can potentially avoid it in Neyland, but a self-contained annexe with its own facilities used independently usually can’t.
Yes, potentially, if your Neyland 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.
Class E permitted development in Neyland 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.
Once a Neyland 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.
Yes, this is genuinely worth having for Neyland projects, confirming the position in writing protects you if the classification is ever questioned, especially at the point of sale.
Absolutely, Neyland annexe clients get the planning classification and building regulations detail handled together, not as separate, disconnected pieces of work.
