This idea can be applied on small house design. This is a great idea about a house that lies inside the house! The uniqueness comes from the idea of open space in home interior, so the external becomes an integral part of indoors. Since, there are open spaces that allow incoming of abundant sunlight, it would not be surprised as there are trees growing in the interior. This home concept is truly blend with nature. Another thing that also impressive from the Inside Out house designed by Takeshi Hosaka (www.hosakatakeshi.com) is its small size. This house occupies the site area of 149.59m2, with building area of 59.23m2 and built in a two-story house!
