ROROOF is a contemporary residential complex completed in 2016, designed by architects Tsuyoshi Komada and Yuka Komada of Komada Architects. Located in Toshima Ward, Tokyo, this innovative housing project reimagines the traditional Japanese rowhouse typology for modern urban living. The structure seamlessly combines multiple dwelling units within a cohesive design that respects both individual privacy and communal spaces. Through thoughtful spatial planning and careful material selection, ROROOF demonstrates how contemporary architecture can honor vernacular building traditions while meeting the demands of contemporary city dwellers seeking community-oriented residential solutions.
