Inside, the design of this small house filled with wood, fast in warm honey and abundant sunshine. From the outside, the house features steel metal panel walls and roof cladding, with a broad area of the sliding glass blur the boundaries between indoors and out. Two-story home features upstairs loft overlooking the main floor open concept house plans. This is a very interesting idea of modern design using a sharp contrast between cold and warm; the cool metal facade and friendly, the interior wood. We love Japan a small home design ideas and in only 624 square feet, this compact contemporary cottage by architect Toyo Ito packs a lot of character into a small space.
