RTA Studio says it's found a way to strip hundreds of thousands of dollars from the cost of building a home.

A New Zealand architecture company has designed a three-bedroom house that three people can assemble in six weeks for $335,000.

RTA Studio just constructed its first ‘Living House’ in Rotorua.

It is 85sqm and designed for quick assembly once the foundations are in place, the cost includes a functional kitchen with appliances as well as flooring, lighting, carpets and heating. It does not include the land value.
