Garage Conversion Planning Permission in
Cobham (Surrey)
Converting a Cobham garage into a bedroom, office, or gym is often a straightforward internal job needing no planning application at all – but turn it into fully separate living space with its own kitchen and entrance, and you’re in different territory entirely. We tell you honestly which one applies.

Whether a Cobham garage is attached to the house or stands alone at the end of the drive genuinely affects how it’s treated. An integral garage becomes an extension of the existing house internally, while a detached garage conversion can raise separate questions depending on what it’s being turned into.
The other genuine trigger in Cobham is intended use – converting a garage into an extra bedroom or office reads very differently to converting it into fully self-contained accommodation with its own kitchen, bathroom, and entrance, which can tip into needing full planning permission as a material change of use.
We don’t take a Cobham garage conversion at face value. Attachment type, proposed external work, end use – all three get checked properly before any conclusion.

Garage Conversion Planning Permission FAQs for Cobham
Can I convert my Cobham garage without planning permission?
Often yes, it’s exempt – a conversion that keeps the same external walls, roofline, and doesn’t add windows or doors facing a road is commonly permitted development in Cobham, though Building Regulations still apply.
Does it matter if my garage is attached or detached in Cobham?
Yes, it can – an attached or integral garage in Cobham is generally treated as part of the existing house, while a detached garage conversion can raise separate questions depending on the proposed use.
Does separate living accommodation need planning permission in Cobham?
Usually yes, full permission is needed – converting a garage into genuinely self-contained accommodation with its own kitchen, bathroom, and entrance in Cobham typically counts as a material change of use, requiring a full application.
Do I need Building Regulations for a Cobham garage conversion even without planning permission?
Building Regulations are a completely separate, mandatory requirement in Cobham, since garage floors typically sit below the house’s damp-proof course and need proper conversion to habitable standard.
Do new windows on my Cobham garage conversion need planning permission?
New openings, a raised roofline, or an extended footprint are the changes most likely to require permission for a Cobham garage conversion, even where the internal work alone wouldn’t.
Is there any upfront payment needed for Cobham?
There’s no charge involved for the Cobham first look – pricing only comes up once we’ve actually worked out what your garage conversion needs.
