How Much Garage Do You Need

The trend these days seems to be for double garages……… but how many of them have two cars in them. My guess would be about 10% and probably close to half never have a car in them.

Some are just a home for junk that really should go to the tip. Some are really the equivalent of the Aussie boy’s shed with a workbench and shelves of tools. Others are a storage place for bikes and barbies, or even a location for the pool table. My double garage can still get one car in but the remainder is a combination of all of the above.

With narrower blocks a problem can be the garage dominates the rest of the house. When you come to sell not many will want a house that looks more like an industrial lock up storage than a home, like This House.


Typical internal garage dimensions are:

  • Single garages – 3.5 metres (wide) by 6 metres (long) with a door around 2.5m wide.
  • Double garages – 6 metres (wide) by 6 metres (long) with a door around 5m wide.

These garages should fit a big Aussie car such as a Falcon or Commodore, which are around 5m long by 1.9m wide.

Even a big four wheel drive such as a Landcruiser  is only really taller rather than much longer or wider than a Falcon. The 4WD would still be no more than 5.5m long with a bull bar on the front and tow bar behind.

Alternative Layouts

In the past I have had a single carport for parking the car with a separate garage/workshop at the back as my shed, which seemed to work well.

Another option may be to have a garage and a half!  This could be either:

  • 9 m long by 3.5 m wide with the back half being the store room/shed.


  • 6m long by 5m wide with shelves and/or a workbench along one or both side walls. This would work better if you wanted a large door through to the back garden.

Not enough room? . . . perhaps an underground/basement garage is the way to go. (see this link to find out more: Underground Garage)
