A 2010 parking guide still shapes the answer
In October 2010 Ashford Borough Council adopted its Residential Parking and Design Guidance. Part of it has since been replaced by policy TRA3 of the Local Plan 2030, but its layout advice still stands, and one line in it matters to anyone with a garage on a newer estate. The council said it would be unlikely to agree to approved parking being converted to habitable floorspace unless replacement parking could be provided.
The same document admits something every Ashford householder already knows. Many garages are used as stores, not for cars. So the council stopped counting them as allocated spaces on suburban and rural schemes, and officers applying TRA3 say plainly that garages are not considered to provide parking spaces. On a house approved under those rules, the spaces the planners relied on were usually on the drive.
Don't read that as a green light. The guide also says the council will use conditions to keep approved parking in use for good, and where a car barn or car port forms part of that parking, conditions often stop you fitting doors to it. Your planning history decides which of these applies.
Finding out what your permission says
The council's own planning FAQ is blunt about it. You may need permission if a condition on the original consent for your house requires the garage or parking to be kept, or if your permitted development rights have been restricted. Open the council's planning maps, switch on the planning history layer and look up the consent for your estate. The conditions are listed at the end of the decision notice.
If a condition does apply, the planners will look at how much off-road parking your plot can offer to make up for the lost garage. For a definite answer before you spend money, apply for a Certificate of Lawfulness for proposed development.
What the space can become
Here is how each route fits Ashford houses and Ashford rules. Each has a full guide.
Integral garage. The garage built into the body of the house. It already shares walls and heating runs with the house, which makes the build simpler, but this is the type most likely to be tied by a parking condition. Check the decision notice first.
Single garage. One room, usually. Bricking up the door opening usually needs a new foundation under the infill wall, and on the town's clays building control will want to see how deep it goes.

Home office. The favourite for people who commute to St Pancras two or three days a week and work from home the rest. A proper data cable matters more than a fancy desk.
Bedroom. A ground-floor bedroom needs an escape window unless its door opens into a hall that leads straight to an outside door. If your house sits low by the Great Stour or East Stour, look at the flood map before you put anyone to sleep down there.
Utility or playroom. Keeping part of the garage as storage and turning the back into a utility is a common compromise on newer homes, where a parking condition may make full conversion harder. Ask the planners whether a part conversion still counts.
Double garage. Usually found beside a detached house, and detached houses are about a third of the borough's homes. Converting one bay and keeping the other for a car is often the easiest way past a parking condition.
Detached garage. A detached garage kept as a workshop, gym or office for the household is ancillary to the house, and the Planning Portal says a hobby workshop typically needs no permission. Somewhere a relative lives is different. Ashford's annexe policy expects that to stay clearly dependent on the main house.
Gym or studio. For drums or a music studio, a garage wall shared with next door on a semi will need serious acoustic work.
Planning and building control. Two separate approvals. Planning depends on your house's history and on whether it is listed or in a conservation area. Building Regulations approval is needed almost every time a garage becomes a habitable room.
Cost and value. No prices here. A new foundation, a raised floor and a replacement parking space can each move the figure a long way. Three builders on site will tell you more than an average figure on a web page.
What Ashford building control will look at
The council's building control team lists garage conversion as its own category in its fee schedule, separate from extensions, and you can go by full plans or building notice. Full plans is the safer route if the infill wall needs new footings or the floor has to come up.
Expect them to ask about the floor first. A garage slab sits lower than the house and has no insulation, so it is normally built up with a damp membrane and insulation to meet the house level. They'll also check ventilation and how you would get out of the room in a fire.
Radon protection may be needed in a new habitable room where the radon map shows a raised potential. Look up your postcode on the UKradon map, or ask the surveyor when they visit.

Questions people in Ashford ask
My Ashford house was built in the last twenty years. Is the garage likely to be protected by a condition?
It might be. Since 2010 the council's parking guide has said it will use conditions to keep approved parking in use, and its planning FAQ lists that as a reason a conversion may need permission. Look up the original decision notice on the council's planning maps and read the conditions.
The council never counted my garage as a parking space. Does that mean I can convert it freely?
Not automatically. On suburban schemes since 2010 the council has not counted garages as allocated spaces, which helps your case, but a condition can still require the garage to be kept. If in doubt, a Certificate of Lawfulness settles it.
We have an open car barn on our estate. Can we put doors on it and use it as a store?
Check first. Ashford's parking guide says the council uses conditions to remove the right to fit doors to car barns and car ports that form part of approved parking. If yours has one, fitting doors needs permission.
Do I have to use the council's building control for a garage conversion?
No. You can use the council's team or a registered private building control company. The council's team has its own structural engineer and treats garage conversions as a separate category, with a choice of full plans or a building notice.
