This modern round home designed by Ciel Rouge takes its prized spot cliff side overlooking the sea in Japan. Straying from convention in concept and in practice, this  contemporary style house boasts a rounded facade with natural elements of site, that allow the interior to experience the free flow of natural lights and the fresh breeze as well as providing panoramic views of the surrounding landscape. A sunken interior courtyard gives the house plan a private piece of the great outdoors, enclosed in glass and overlooked by the home’s living areas. But looking out over Japan’s sparkling shoreline, the best views are to be had from the rooftop garden of the house, where lush plantings and gardens transform a roof into a hotspot.
