Garage Conversions in Dorking
If a garage has turned into a dumping ground for bikes, boxes and things nobody quite knows what to do with, converting it into usable space is often more straightforward than building an extension. This site puts homeowners across Dorking, the Holmwoods, the Mole Valley villages and neighbouring towns in touch with a local installer experienced in garage conversions, from a simple insulated store to a full extra bedroom or office. Nothing here commits you to anything, and comparing quotes from a couple of local installers before making a decision is entirely up to you.

What counts as a garage conversion
Converting a garage means taking the existing structure, whether it's built into the house, attached alongside it, or standing on its own in the garden, and turning it into a room people actually live in. Homeowners in and around Dorking typically end up with a spare bedroom, a home office, a playroom or a bit of extra living space, rather than a smartened-up store cupboard.
Because the structure already exists, a conversion is usually a smaller undertaking than building an extension from scratch, though the work involved, floor, walls, roof, damp-proofing, insulation and services, is genuinely comparable to building a new room.
Planning permission and building regulations
Converting a garage usually sits outside the need for planning permission, since the outside of the building tends to look much the same once the work is done. This generally falls under permitted development, and GOV.UK's guidance on planning permission sets out the general position for England and Wales.
Which council handles any planning or building control query depends on exactly where a property sits. Dorking itself, along with Leatherhead, Ashtead, the Holmwoods, Box Hill Village, Mickleham, Westcott, Brockham, Betchworth, Buckland and Great Bookham, all fall within Mole Valley District Council. Reigate and Redhill are covered by Reigate and Banstead Borough Council, Epsom by Epsom and Ewell Borough Council, and Cobham by Elmbridge Borough Council.
Permitted development rights can be more limited on listed buildings, in conservation areas, or where a previous planning condition has removed them, so it's worth checking a specific property before assuming a conversion won't need an application.
What actually changes in a garage conversion
It's common for a garage floor to sit below the level of the rest of the house and to have no proper damp-proof membrane, so raising or relaying it is one of the more frequent jobs on a conversion. Insulation in the walls and roof is usually minimal or missing altogether compared with the main house, and bringing those up to a similar standard tends to be where most of the work and budget goes.
A garage door facing the road is commonly swapped for a section of wall with a window built in to match the house, although some homeowners choose to keep a garage-style door in place and use a partition to screen off storage behind it. Where the garage backs onto or shares a wall with next door, the Party Wall etc. Act 1996 can come into play, and GOV.UK sets out how and when neighbours should be notified before that kind of work starts.
Attached, integral and detached garages
Converting a garage that's built into the house, or that shares a wall with it, tends to be the simpler job, largely because electricity and other services are usually already nearby. A detached garage set back in the garden, common on some of the older properties around Dorking's villages, can still be converted, but running power, heating and sometimes drainage out to it needs more planning.
Ground conditions across the Mole Valley
The Dorking area sits where the chalk of the North Downs meets Weald clay and greensand further south, so ground conditions can vary from one street to the next, particularly close to the River Mole or on the lower-lying land around the Holmwoods. A local installer will usually want to see the garage in person, or good photos and dimensions, before confirming what the floor and any groundwork will involve.
Comparing written quotes
Quotes for a garage conversion can differ quite widely, driven by factors such as the garage's size, whether it's attached or standing apart from the house, the finish specified, and the extent of rewiring, insulation and plastering the job needs. Asking more than one local installer to quote against the same brief is the surest way to compare them properly, rather than judging on a single headline number.

Frequently asked questions
Will converting my garage need planning permission?+
Usually not, since the outside of the building typically stays much as it was, which normally counts as permitted development. That can change if your property is listed, sits in a conservation area, or has had permitted development rights taken away by an earlier condition, so it's worth confirming with the relevant council before you start.
Which council covers my property?+
It depends where you are. Mole Valley District Council covers Dorking itself and most of the surrounding villages, Reigate and Banstead Borough Council covers Reigate and Redhill, Epsom and Ewell Borough Council covers Epsom, and Elmbridge Borough Council covers Cobham.
Will I need building regulations approval?+
Very likely yes. A garage is built to a lower standard than a room meant for everyday living, so once it's converted, building regulations step in to cover insulation, damp-proofing, ventilation, electrics and fire safety.
How much does a garage conversion cost?+
Cost hinges on things like the garage's size and current state, the finish you have in mind, and the amount of rewiring, insulation and plastering the job calls for. The only real way to pin this down is to have a local installer put together a written quote for your specific garage.
If my garage is built into the house, can it still be converted?+
Yes, and this is generally the easier of the two to convert, because it's already tied into the house and services such as electricity are typically nearby already.
What if my garage stands separately from the house?+
It can still be done, though access, drainage, and services like electrics and heating usually take more working out, since they all have to be extended out to a standalone building rather than picked up from a shared wall.
