‘boo hoo woo’ by yutaka kawahara design studio, is a response to the client’s wishes of a house that provided more insulation to account for the harsh japanese winters. not being able to afford a new house completely, three additional rooms were fashioned to connect to an existing dwelling. each zone is attached at a 30 degree tilted axis, opening up to hug a surrounding garden. the three masses are distinct separate spaces but can also exist as a single unit connected by a deck, and have all the amenities to be livable without the need to be affixed to the main home. a bathroom and kitchen occupy the wedge-shaped voids between the volumes. the design of the roof differs and is characterized for the particular areas. various steeped or rounded canopies are applied to the structure to service the snowfall. a tatami mat room diverges from the theme with a lower ceiling height and flat covering. the assemblage of the shed-like buildings has a colorful exterior, with asphalt patterned tiles that decorate the rooms individually.
