Types of garage conversion in Southampton, and the rooms they make
Types of garage conversion in Southampton start with the garage itself: single, double, integral, attached, detached or partial. Pick yours, then the room it should become; each is measured, drawn and priced item by item before you agree to anything.

(Step one: the garage)
Six kinds of garage and how each converts
The garage you start with sets the scope: how much floor and wall needs finishing, whether a bedroom sits above, and which hall or room it will open from.
-
01
Single garage conversion
The side garage found beside many 1930s semis in Shirley and Bitterne: room for a double bed, a desk or a sofa once the door opening is filled with a footing, wall and window.
See single garage conversions -
02
Double garage conversion
Common on bigger 1970s detached plots in Chandler's Ford: enough floor for two rooms, a bedroom with its own shower room, or one family room across both bays.

03
Integral garage conversion
Part of the house, as on many newer homes around Boorley Green and Hedge End, usually under a bedroom. Most of the work is the front wall, a raised floor and fire-resisting ceiling linings.

04
Attached garage conversion
Joined to one side of the house but roofed separately, often flat or lean-to. The roof and the party wall are checked first, then a doorway links the room to the hall.

05
Detached garage conversion
Free-standing, at the bottom of the garden or the far end of the drive, like many on 1990s plots around Romsey. Suits a garden office, studio or gym, with a cable (and pipes if needed) laid from the house.

06
Partial garage conversion
The back of the garage becomes a room and the front stays a store behind the original door: useful for bikes, the mower or a utility area, as on many Hedge End estates.

Garage conversion ideas: nine rooms to choose from
One garage can end up as very different rooms. What changes between them is plumbing, ventilation and how the space connects to the rest of the house.

A second lounge, playroom or TV snug, insulated so it stays warm and quiet, with space for a full-size sofa.

05Garage to kitchen
The kitchen opened through to the garage to make a kitchen-diner. Taking out the wall normally means an engineer-designed steel beam, approved before anything is removed.

A level, insulated floor that takes heavy kit, ventilation for hard sessions, bright even light and power where each machine will stand.

(Choosing)
Picking the right garage conversion for your household
- 01
Begin with who will use it
A guest room, a place to work, a playroom and a home for a parent each ask for different things. Note who will be in the room, at what times and for what, and the layout tends to follow.
- 02
Find out what the garage allows
Headroom, the slab, the drain runs and whatever sits overhead set the limits. Side garages on Shirley and Bitterne semis suit a bedroom or study; integral garages on newer Eastleigh-borough estates sit under a bedroom and need fire-resisting linings.
- 03
Consider parking and storage
The garage’s storage goes, and on some estates a planning condition keeps it for parking, which is worth checking early. A partial conversion keeps a store, and a door from the hall makes the room feel original rather than bolted on.

A quick guide to why some rooms cost more than others: plumbing, additional circuits and any steel beam make the biggest difference.

Questions about garage types
What each kind of garage can and cannot become. Ring us for anything not covered here.
Call 07930 368740Can every garage be turned into a room?
Most can. The survey looks at the foundations, walls, roof and headroom. A very low ceiling, a slab far below the house floor or a public sewer under the garage can complicate things, and we tell you before you spend anything.
Which garage conversion gives the most space?
A double: about twice the floor of a single, room for two separate rooms, a bedroom and its own shower room, or a single large family room.
Can I keep some storage after converting?
Yes. A partial conversion turns the rear into the room and keeps the front as storage, still opened by the existing garage door, with an insulated stud wall dividing them.
Does a detached garage conversion need planning permission?
Used as part of your home, for example as an office, gym or studio, a detached garage usually does not. Turning it into a separate dwelling where someone lives independently normally does. We check the position for your address at the survey.
Can a converted garage include a bathroom or kitchen?
Yes. What matters is whether waste can fall to the drains and how the room will get rid of moisture. Both are settled during the survey, ahead of any price.
Could a garage work as an annexe for a family member?
Yes, typically as a bedroom, shower room and compact kitchen. Where the relative shares the household, planning permission is often not needed; where the annexe would work as a separate home, an application is normally required. The Valuation Office Agency may also band a self-contained annexe separately for council tax.
