Japanese architect Kohei Yukawa has designed a house for himself and his family in a suburb of Osaka, featuring flexible living spaces arranged around a double-height atrium with a tree at its centre. Yukawa, co-founder of Yukawa Design Lab, designed the Margin House in response to the unique conditions of its urban site in Ibaraki City, to the north of Osaka.
