Australian house is interesting in this picture. Notice, it's build up of car trailer, with attached easy-to-put-down 3 rooms. Would you like to move away from this bloody place? Live 1000 km far from badly gossiping neighborhood? No problem. Just put down 10 light walls & go ahead. This is REALLY COMMON way of living all around Australia. We met some guys, who lived couple of years in a BUS - they moved where they liked to move. With whole house, fully equipped house for 80.000,- bucks. In a bus.
