On Wellesley, the answer starts with an application
Most English homeowners can turn a garage into a room without asking the planners, because internal work that doesn't enlarge the house usually needs no planning permission. Parts of Wellesley are the exception. Rushmoor's Article 4 direction for specific phases of the estate, in force since January 2020 and confirmed that July, lists the conversion of a garage to form a habitable room as something that now needs planning permission.
Two details help. Where you need consent only because of the direction, the council makes no charge. It also says the controls reflect covenants already on the properties, so your deeds may have something to say as well. The phases covered are shown on a map rather than listed by name, so check yours on the council's Article 4 page before a builder measures up.
The direction also covers windows and new hard surfaces at the front, so a new window plus fresh paving out front may be caught twice over.
What the space can become
Integral garage. The garage built into the house. On a newer home this is where a planning condition or covenant is likeliest to sit, and the Planning Portal singles out new housing developments for that reason. Read your plot's decision notice first.
Planning and building control. Two different questions. Planning depends on Wellesley, any condition on your house, a conservation area or a listing. Building Regulations approval is needed in almost every case where the garage becomes a habitable room.
Single garage. One decent room. The infill under the old door opening may need its own foundation, and on Aldershot's sandy ground building control will want to see what it sits on.

Bedroom. The popular choice for a growing family in a small house. Plan the escape route from the start, because building control checks fire safety as its own stage. Near the Blackwater, check the flood map first.
Home office. Fine for your own desk job. If clients or staff start arriving, the Planning Portal says running a business from a garage usually needs permission, because the use stops being purely domestic.
Utility or playroom. A part conversion, with storage kept at the front, is a sensible compromise where losing the whole garage would worry the planners. Ask whether a part conversion still falls under the Wellesley control.
Detached garage. Kept as a gym, workshop or office for the household, it stays part of the home, and the Planning Portal says a hobby workshop typically needs no permission. Make it somewhere a relative lives and Rushmoor's guide warns that a self-contained outbuilding may be treated as a dwelling in its own right.
Double garage. If you have one, converting one bay and keeping the other for a car answers most parking worries in one go.
Gym or studio. On a semi where the garage backs onto next door's, the shared wall needs sound insulation before you put a drum kit or a treadmill against it.
Cost and value. No prices on this page. A new foundation, a floor that has to come up to house level and a replacement parking bay are the things that swing an Aldershot quote.
Rushmoor doesn't count your garage as parking
The council's Car and Cycle Parking Standards SPD, dated March 2024, is frank about garages. It says they are most often not used for cars, which end up parked elsewhere, while the garage itself is converted or filled with storage. For that reason, garages provided with new development don't count towards the parking standard at all.
Two catches remain, though. The council's 2020 householder design guide tells applicants to avoid losing off-street parking spaces, so if your car really does live in the garage, have a plan for where it goes. And the parking SPD allows a condition keeping parking spaces, inside or out, for cars only on a constrained site. If the original permission for your house carries one, the conversion needs consent.
Want to keep bikes in what is left of the garage? Rushmoor only counts a single garage as cycle storage if it measures at least 3m by 6m inside. Rushmoor's standard bay in front of a garage is 5.5m by 2.5m.
Front walls in the older streets
In Cargate the Article 4 direction controls any new, replaced or altered window or door that can be seen from the road, plus hard surfacing and front walls. Swap a street-facing garage door for brickwork and a window there and you need planning permission, even though the work inside needs no consent. The appraisal mentions modern single-storey garages slotted between some of the larger houses, and complains about front walls lost to parking.
In Manor Park and Aldershot West no such direction applies, but match the brick and line the new window up with the ones above it.
Radon data for Rushmoor is thin. Public Health England's 2016 survey found none of the eight Rushmoor homes it measured at the Action Level, so check your address on the UKradon map anyway. Rushmoor's own building control team handles the town and inspects foundations, drains and insulation before it is covered.

Questions people in Aldershot ask
Our Wellesley house came with a garage we use as a store. Do we pay to apply for a conversion?
If your phase is covered by the Article 4 direction, you need planning permission to make the garage a habitable room. Rushmoor says there is no charge where the application is needed only because of the direction. Check your deeds for covenants too.
Will losing the garage push us below Rushmoor's parking standard?
Not on its own. The 2024 parking SPD doesn't count garages on new developments as spaces. Adding a bedroom can raise the number of spaces expected, though, and you would only need to cover the extra demand.
We're in Cargate. Can we fit a window where the garage door is?
Yes, with planning permission if it can be seen from the road. The Cargate Article 4 direction covers adding or altering windows and doors on street-visible walls.
Can my son live in our converted detached garage?
Using it as a bedroom tied to the house is one thing. If it has its own kitchen and front door, Rushmoor's design guide says a self-contained outbuilding may be treated as a separate dwelling, which would need planning permission.
