Couple built a two-story house for $12,000

Sam and Simone realized they could build a house for the same amount they would have spent on a year's rent in Australia. So they did, in one of their parents' backyard. It looks great.
From Living Big in a Tiny House:

In this video, we discuss how they were able to construct their tiny house for such an affordable price and tips for building tiny houses for less. Especially in a country like Australia, where the material cost of building can be very high!
As students of wildlife and environmental sciences, the couple now have plans to regenerate the property where the tiny house is parked. They are also using the tiny house as a base to launch a new online business. I hope you enjoy this full video tour of this stunning tiny home.
