Personally, I think he's out of the box thinking in designing a solution to the constraints of his small apartment may have a huge contribution to developing countries. Most of the population in these countries can barely afford their small homes. The concept behind his design can be adapted to the designs of the low-cost housing in these countries.
His concept will definitely increase the comfort and standard of living of this low-cost housing without drastically increasing the prices of these homes. Since the cost of the project is still well beyond the reach of the majority of the masses. I guess the next challenge would be to look for cheaper alternatives in the materials, fixtures, and mechanisms used in his design.
