Seven metres by three: the Suffolk measure
Get a tape measure out before you call anyone. Suffolk County Council's parking guidance, which the borough's design guide points to, only counts a garage as a parking space if it is at least 7 metres long and 3 metres wide inside, with a door opening of 2.4 metres or more. Plenty of older single garages in town fall short.
Most conversions never need planning permission, but a condition, a listed building or a change to the front in an Article 4 street will put yours in front of a planner. The borough's design guidance warns that the council may resist schemes that lose off-street parking, and that extra bedrooms can mean extra spaces. A garage too small to count was never one of those spaces, which is a fair point to make in your application.
Cul-de-sacs off Brazier's Wood Road and the newer estates
The council's character study is blunt about the later 20th-century housing off Brazier's Wood Road, in the Gainsborough area. These larger semis and detached houses "were designed with driveways and garages", built in buff and brown brick as well as red. Where the drive is long enough, the car simply moves out onto it.
On the newest streets the paperwork matters more than the bricks. The Planning Portal says garage conversion rights are sometimes removed by condition, and tells people on new housing developments to check first. If you've bought on Ravenswood, where building on the old airfield began in 1999, or on Henley Gate in the Garden Suburb, get a copy of the permission your street was built under and check it for garage conditions before paying for drawings.
Ten ways an Ipswich garage gets used
Integral garage. Sitting under the main roof, it is the simplest of the four to build. Check for a removed-rights condition first, then expect the floor to be raised to meet the hall.
Single garage. If it measures under 7 by 3 metres it wasn't a counted car space anyway. The new wall where the door was usually needs its own footing, and the inspector looks at the trench before any concrete is poured.

Home office. A favourite for anyone working from home a few days a week. Heated and used daily, it is a habitable room, so it needs building regulations approval like any other.
Utility or playroom. Keep a store at the front behind the original door and the elevation hardly changes. In the Norwich Road or Marlborough Road streets that can keep the planners out of it.
Double garage. Keep one half at full size for a car and Suffolk's guidance still counts it, which takes the heat out of any parking question.
Bedroom. Building control will check how you'd get out in a fire, plus light and ventilation. Near the Gipping or the Orwell, look up the flood map before putting anyone to sleep downstairs.
Gym or studio. Where two garages sit back to back between a pair of semis, the party wall carries every thud. Line it before the plasterer comes, not after the first complaint.
Detached garage. Kept as a workshop or gym for the household, it normally stays part of the house in planning terms. A relative living there independently is a different use and needs an application.
Planning and building control. Planning only comes into it where a condition, a listing or one of the Article 4 streets applies. Building regulations sign-off is the part nobody avoids.
Cost and value. We won't quote a figure. A raised floor, a new footing and a fresh drive can each move the price, so get three builders to look at the garage itself.
Front walls and hardstandings in the Article 4 streets
Swapping a garage door for brick and a window changes the front of the house. In the residential Article 4 areas, the Christchurch Street and Westerfield Road streets, Anglesea Road and Norwich Road, and Marlborough Road among them, the council says material alterations to elevations need planning permission. Its guidance adds that plastic or aluminium replacement doors and windows will generally be refused. On a corner plot you have two frontages to think about.
Losing the garage often means paving the front garden instead, and that is controlled too. The council says new hardstandings in those streets should be refused unless they can be placed or screened so they don't spoil the street. Elsewhere, its design guidance favours permeable surfaces or planted strips, and resists front parking that costs a good tree.
A new dropped kerb is Suffolk County Council's decision as highway authority, not the borough's. The county wants a standard space 5 metres deep and 2.5 metres wide, and on an A, B or C road you need planning permission for the access as well.
Before the builder starts
Ipswich Borough Council runs its own building control team, though a private approved inspector is an option. The Planning Portal expects the old door opening to be filled with new wall, possibly with a window, on a new foundation. New habitable rooms in a radon-affected area may need radon protection, so check your address on the UKradon map or ask building control.

Questions people in Ipswich ask
Our garage off Brazier's Wood Road is too short for a modern car. Will the council object to losing it?
Usually the council never sees it, because internal work rarely needs permission. If an application is needed, point out that Suffolk's guidance only counts a garage of at least 7 by 3 metres inside, and show the car still fits on the drive.
We live on Marlborough Road and want to brick up the garage door. Do we need permission?
Very likely. The Article 4 direction there covers alterations to elevations facing the road, and the council generally refuses plastic or aluminium replacement doors and windows. Talk to the council before ordering anything.
Can I pave the front garden on Westerfield Road to replace the garage space?
Some of Westerfield Road is in the Christchurch Street Article 4 area, where the council says vehicle hardstandings should be refused unless they can be placed or screened. You'll also need Suffolk County Council's consent for the dropped kerb.
Our Ravenswood house has an integral garage. Where do we look for restrictions?
Check the planning conditions for your phase and the covenants in your title deeds. Whatever they say, the room itself still needs building regulations sign-off.
