What Theale Families Need To Know About Annexes

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

How We Help in Theale

We start every Theale annexe project by establishing the real starting point, a mobile structure within Caravan Act limits, an incidental outbuilding, or genuine independent living space, since that single distinction shapes everything that follows.

Your Theale application or certificate, whichever applies, is built around what your local council specifically expects to see, not a generic template.

Structural and building regulations work for Theale annexe projects is handled properly from the outset, informed by real experience with this kind of project.

Why Theale Families Trust Our Annexe Specialists

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

Where a Theale 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.

Theale Granny Annexe Questions Answered

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

Can my Theale annexe qualify as a mobile home?

Yes, potentially, if your Theale 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 Theale?

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

Once a Theale 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 Theale annexe?

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

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