Oldham houses built after the mills
Oldham is a terraced town first. Valuation Office figures in the council's 2024 housing needs assessment put terraces at 44.7% of homes, and a terrace with a back yard rarely has a garage to convert. The garages belong to the later stock. Homes built from 1965 to 1982 make up 22.5% of the borough, and roughly another 18% followed after 1982.
That later stock is mostly semis, detached houses and bungalows. Semis are a quarter of all homes, bungalows close to a tenth, and those are the plots where conversions here usually start.
On a newer house, look at the planning history before the design. A condition on the permission for your house, whether it keeps the garage for a car or removes householder rights altogether, can turn a job that looked free of planning into an application. The council's planning team can tell you what applies to your plot.
Five metres of drive, parked square to the road
Once the garage becomes a room, the car usually moves onto the front garden. Oldham's Light Duty Vehicle Crossings Policy (April 2024) is stricter than many people expect. The parking area has to be at least 5 metres deep and 3 metres wide, with the car at right angles to the road. Angled or parallel bays are refused.
The council can accept 4.7 metres where the logbook shows the car won't overhang the footway. That concession isn't open to houses built after 1 April 2018, houses that already have off-street parking, or houses whose space was cut down by a porch or extension. Only the council builds the crossing, paid for in advance, once the drive is finished. Onto an A, B or other classified road you need planning permission as well, and a front garden surface over 5 square metres must be permeable unless permission is granted.
The garage itself carries little weight. What decides most cases is the drive in front, so measure the front garden before anything else.
Matching the conversion to the house
Single. The attached garage beside a 1970s semi. Most of the work is in the floor and in infilling the door opening, where the footing under the old threshold has to be dug out and checked.

Integral. With the garage already under the main roof, most of the structure is there. The Planning Portal singles out newer housing developments as the place to check whether conversion rights were taken away, so start there.
Bedroom. Suits a bungalow, adding a bedroom with no stairs to climb. Where the only way in is through another room, building control will want an escape window with a clear opening of at least 450 by 733mm, its sill no higher than 1.1 metres.
Office. The insulation standard is the same as for a bedroom, because it's a habitable room. LABC also caps glazing at about a quarter of the floor area, so a wall of glass where the door was won't pass without other trade-offs.
Utility or playroom. On a semi with a narrow galley kitchen, moving the washing machine into part of the garage is often worth more day to day than a whole extra room. A playroom counts as living space and is built to that standard.
Gym or studio. Paired semis often have their garages back to back. LABC says a party wall of less than 200mm dense block usually needs extra sound work, and a gym is where you'll want it.
Double. Mainly a detached house job. Keeping one half as a garage also helps with the 5.5 metre space the crossings policy wants in front of a garage door, if the drive is tight.
Detached. Turning a freestanding garage into your own gym or study is one thing. Making it a home for somebody else to live in is a different use, and planning permission can be needed for that even if the building work is small.
Planning and building control. Work inside the shell normally needs no planning application, unless a condition or a listed building gets in the way. Building regulations approval is a separate question, and converting to living space nearly always needs it. Oldham Council runs its own building control team, or your builder can use a registered approver.
Cost. We don't publish Oldham prices. A new drive and council-built crossing can add a good share to the bill, and a stone-faced front wall in Saddleworth costs more than block and render on a 1970s semi.
Saddleworth fronts, low floors and the river valleys
In the stone villages a garage door is often the newest thing on the front of the house. Most of Oldham's conservation areas are in Saddleworth, and there the council asks for design and materials that suit the historic character. Match the stone, and line the new window up with the ones above.
Part of Saddleworth falls inside the Peak District National Park, where the Park Authority deals with planning. Its alterations and extensions design guide doesn't cover conversions, but its garage advice is telling. It calls the garage door the largest element on a front elevation, prefers side-hung timber doors with vertical boarding to up-and-over steel, and wants doors set back at least 150mm from the wall face. A conversion that keeps that recess, with a timber-framed window filling it, sits more comfortably than flush infill.
Garage floors are nearly always lower than the house, which matters near the Beal at Shaw and in Uppermill and Greenfield, where the council's flood study records repeat floods. The Environment Agency's standing advice recommends floors at least 600mm above the estimated flood level, or resistance and resilience measures where that can't be done. A bedroom is the room to think hardest about.
Radon is the other check below floor level. Conversions in the higher radon bands need basic or full radon protection under the building regulations, so look your address up on the UKradon map before the floor is specified.

Questions people in Oldham ask
Our drive in Royton is about 4.8 metres. Will Oldham give us a dropped kerb?
Possibly. The standard is 5 metres, but the council can accept down to 4.7 metres if your car's logbook shows it won't overhang the footway. That concession doesn't apply to homes built after 1 April 2018 or to ones that already have off-street parking.
Our house is on a newer estate. Could a condition stop us converting the garage?
It could. Ask Oldham's planning team which conditions apply to your plot before paying for drawings.
Who builds the dropped kerb, us or the council?
The council. Oldham's policy says only the council can do the work, you pay in full first, and the crossing isn't built until your new drive is finished.
Our cottage is in the Saddleworth part of the National Park. Who do we apply to?
Planning goes to the Peak District National Park Authority, not Oldham. Building regulations are still handled by Oldham Council's building control team unless you use a registered approver.
