Eternal
Eternal is a residential house built on a sloping site in Hyogo Prefecture, Japan. The elevation difference is used to place volumes both below and above ground, forming a continuous space from the basement to the upper floors. The basement holds a garage and a hobby room, while the living areas are above the first floor. A large opening on the south side brings in daylight and distant views while limiting sight lines from the street. The structure combines reinforced concrete below ground with large-section laminated timber and metal joints above.
Eternal Residential House by Michihiro Matsuo has been selected as a grand illustration of architectural design by the A' Design Award & Competition. Eternal Residential House earned the Silver A' Design Award in Architecture, Building and Structure Design in 2025. The A' Architecture, Building and Structure Design Award is a highly prestigious, international, juried design prize that rewards superior design of skyscrapers, museums, residential buildings, commercial complexes, educational institutions, religious structures, infrastructure designs, landscaping projects and more.
