the catenary curve feature in ‘double roof house’ by japanese firm SUEP./hirokazu suemitsu + yoko suemitsu, helps to connect the building’s separate spaces and provide shelter from the sun. located in a residential area in yamaguchi, japan, the surrounding neighborhood is mostly low-rise residential houses, which don’t cast any shadows onto the site. the one story building consists of two roofs and is made up of a collection of five box-shaped units, each serving its own function. the different zones are sheltered under a dramatic floating ‘sudare’ (reed screen), which reduces the solar gain into the building by 50%. a small gap between the two structures allows diffuse light to still filter through to the spaces below. sitting comfortably in the landscape the building follows the natural flow of the site’s topography.
