japanese practice three ball cascade architects have recently completed ‘harley in da house’ for a client with an interest in cars and would live on the ground floor, with his parents above. the simple rectangular form of the residence contains several voids to bring natural light into the interior as well as control views in the residential area. a cross-shaped courtyard on the second storey makes four semi-independent private volumes. the spacious garage and living room at street level are separated by a large glass wall, creating a constant visual connection and treating the automobile more as a piece of art on display. the interior is partly illuminated by a full height atrium. dark walnut is used as the flooring material as well as integrated furniture and garage door, with metal panels as a skin.
