Getting The Melbourne Annexe Question Right First

A granny annexe in Melbourne can follow three genuinely different routes. A structure that meets the legal definition of a caravan under the Caravan Sites Act 1968, capable of being moved by road in one or two sections and within maximum dimensions of 20 metres by 6.8 metres with an internal height of 3.05 metres, can often be sited without planning permission provided it remains ancillary to the house.

An outbuilding used incidentally to the enjoyment of the house, a home office, gym, or storage, can fall under Class E permitted development, but the moment it includes genuine sleeping accommodation used independently, it’s no longer considered incidental, and permitted development stops applying.

Where neither route fits, a full planning application is the reality for Melbourne properties, and we confirm this honestly rather than assume.

How We Help in Melbourne

Every Melbourne 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 Melbourne project and prepare exactly what’s needed, a Lawful Development Certificate or a full planning application.

Structural detail and building regulations compliance for Melbourne annexes are handled properly throughout, not bolted on at the end.

The Case For Proper Annexe Advice In Melbourne

We tell Melbourne families honestly whether their annexe genuinely qualifies for the Caravan Act or permitted development routes, rather than defaulting every enquiry to a full application.

Getting the self-containment question right matters more than almost anything else for a Melbourne annexe, and we assess this honestly rather than assume either way.

Structural and building regulations detail is built into every Melbourne annexe project from the start, whichever planning route applies. 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 Melbourne

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

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 Melbourne.

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

Can I use permitted development for a Melbourne annexe?

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

A Melbourne 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 Melbourne annexe?

We recommend it, even where your Melbourne 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 Melbourne annexe?

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