in the japanese city of nagoya, architect hisanori ban has completed a three storey dwelling ringed with concrete bands that help withstand earthquakes. the building is located within a quiet residential neighborhood, whose urban fabric has changed rapidly over the past few years. while many of japan’s reinforced concrete structures have been demolished prematurely as a result of inflexible design, ban sought to create a home that would stand the test of time.

within the rigid outer shell, the dwelling’s flexible timber floorplates allow for potential modification over the coming decades. ceiling heights can be increased and individual wooden elements removed. internal programs are delineated with japanese shōji, establishing a series of connected yet secluded rooms. the concrete cladding also helps insulate areas of the house, ensuring an inherent thermal mass. the home was named ‘everlong’ as the client — an elderly woman — hoped that the structure would remain for many years after her eventual passing.

hisanori ban’s previous work includes a reflective roadside café and a secret garden hidden behind concrete façades. see more projects by bandesign on designboom here.
