based at the top of a hill in a residential suburb of miyazaki city, masahiko sato of architect show has shared their latest project- ‘I-3 house’. the angular property has been developed in response to the location’s climatic conditions which is influenced by its coastal setting. the exaggerated sloping roof contributes in minimizing wind pressure in case of typhoons and allows rainfall to flow off with ease. the whole building has been lifted slightly off the ground to allow the inhabitants to enjoy views of the city and hyuga sea.

the single family home presents a discreet façade with no windows




configured to protect and shelter its residents, the street-facing façade does not feature any windows. externally, the dwelling is clad in a white render with grey accents, juxtaposing with the natural timber grain. the overall form of the building is influenced by the parking and internal spatial configuration. 



in contrast, the rear opens up to the backyard and provides an external area of recreation. the living spaces are presented with sliding glass doors out onto the garden- establishing a fluid relationship between internal and external areas. the kitchen, living and dining have been organized within a double height space illuminated by a large skylight. keeping to japanese traditions, an elevated tatami room is located in the corner and sectioned off by sliding bamboo screens.
