Granny Annexe Planning Permission in Haslemere (Surrey)

Understanding Granny Annexe Planning Permission in Haslemere

Haslemere 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 Haslemere, 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 Haslemere property and plans against all three routes honestly, rather than assuming the most complex one applies by default. A Haslemere annexe needing full planning permission usually needs both, our Building Regulations drawings in Haslemere service covers the technical compliance side, and our structural calculations in Haslemere service covers the engineering detail.

How We Help in Haslemere (Surrey)

We begin every Haslemere annexe project with an honest assessment of the actual plans, size, mobility, and intended use, before any design work begins.

Where the Caravan Act or permitted development genuinely applies to your Haslemere project, we confirm that properly, usually via a Lawful Development Certificate, rather than defaulting to a full application that isn’t needed.

Where genuine self-containment means a full application is required, we build that around what Haslemere’s council specifically expects to see.

What Sets Our Haslemere Annexe Advice Apart

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

Where a Haslemere 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.

Haslemere Annexe Planning Questions Answered

What determines if my Haslemere annexe needs planning permission?

This genuinely depends on your specific plans for Haslemere, 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 Haslemere?

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 Haslemere plans genuinely meet this.

What outbuilding rules apply to a Haslemere annexe?

It depends on genuine use, an incidental Haslemere 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 Haslemere?

Genuine independence is the test in Haslemere, 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 Haslemere?

Strongly recommended for Haslemere 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 Haslemere annexe project?

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