Architect's 'suitcase house' aimed at young people

When humans are forced to settle down on Mars, might we at last start to think about the way we live on Earth? With this question in mind, architect Li Hu has designed a suitcase-like house to explore how people could have minimalistic lifestyle that only meets the essential requirements for survival.

The about 4-square-meter house, on display at China House Vision exhibition in Beijing, discusses future houses and comprises two parts: a hard case that includes the kitchen, toilet, bathroom and air conditioning unit, and an inflatable ballon-like living space used for activities such as reading, drinking tea, doing exercises or enjoying the landscape through windows.

"That's enough," Li says.
