An architect in Israel has created the ultimate in space saving solutions. It's a portable house with all the modern conveniences, and it's only 4 square meters.

Many people dream of upgrading to a bigger home, but with space at a premium in cities all over the world, Hagai Nagar's creation just might come in handy. And the CHU 200 compact home has everything you'll ever need - there's storage space, a mailbox, bathroom and even a fitted kitchen.

Hagai Nagar, Architect/Designer, The Chu 200, said,"CHU stands for compact house unit and the two hundred is the two hundred by two hundred by two hundred centimeters which is the volume of the box. It is a unit, a unit that possess all the functions we know from the regular modern house."

Nagar was asked to design an ecological home for an exhibition in Tel Aviv.

As an architect who is used to designing anything from offices, private homes and clubs around the world, Nagar realized that at any given time only a small fraction of a building is actually being used.

This led to the idea of designing a residence that not only uses less space, but also less material, making it environmentally friendly.

The CHU 200 is made of metal and weighs about 700 kgs. The roof has solar panels to provide electricity and hot water.

The unit can also be attached to external sources of water and electricity.

This is just the prototype, but Nagar claims that some entrepreneurs have expressed interest in producing more.

Hagai Nagar, Architect/Designer, The Chu 200, said, "Some people were talking to me in a serious way about putting it or having many of these stored somewhere and once there is a natural disaster like an earthquake or something instead of living in tents with no water and you just ship it to wherever you need and communities can live around it and enjoy it."

Nagar says he not only wants to challenge the way people perceive space, but he also wants to encourage architects and designers to think outside the box.
