mino terrace

Located in Mino, Osaka, the site sits at the intersection of the traditional north–south farmland grid and the diagonal trajectory of National Route 171, cutting across from northeast to southwest, resulting in a landscape defined by sharp, acute angles. Such geometries are often resolved with triangular or curved forms that neutralize the angle. Here we sought to harmonize our structure with the acute geometry of the site. The previously divided lot hosted early works by the some architect and our firm. However, due to the aging showroom, these were demolished, to be replaced by a new facility. Conceived over six years ago, the program began as a mixed-use facility but had evolved significantly. Ultimately it became clear that the site, program and their environment was shaped by the dynamic flow of movement – of cars, people and nature. The showroom, drive-thru café, and maintenance facility choreograph a flow of vehicles that defines the landscape. The flow of people is also crucial. Visitors ascend through a spiraling corridor, encountering a rooftop terrace as they walk. The roof top terrace serves not only as a physical destination, but also as a metaphor, reminding us of the importance of preserving our natural environment. Guided by the principle ‘All flows should flow smoothly’, the design embraces a ‘less is More’ ethos—reducing environmental load, energy consumption, materials, manpower, and time, while enhancing richness, comfort, and the spatial appeal. A gentle ramp leads to rooftop parking, seamlessly extending the ground-level lot and preserving usable site area. Below, a circulation road serves the drive-thru café, with overlapping paths above to optimize the footprint. The ramp’s columns are carefully placed to avoid disrupting flow beneath; their organic layout and slanted orientation create a structural logic that quietly echoes Zen principles. Beneath the ramp, concrete polygons shape the concourse and approach, accommodating the site’s elevation change while evoking a rock garden—a metaphor for “impermanence”. Over time, the rooftop terrace will grow over with greenery, becoming a suspended expression of nature within a Zen-inspired space-time. Unstable organic soil ruled out piles or ground improvement. The footprint was excavated to a four meter depth, then stabilized with mass concrete, a simpler method of responding to the surrounding environment. This process birthed ‘new ground’. Though artificial platforms were once celebrated, true human activity remains rooted in the real earth. The ground level was made into public space, where people may move freely, while vehicular circulation was elevated above. The boundary between interior and landscape blurs—the outdoors becomes spatial, and the landscape becomes a human-centric interior. As we sense the fragility of the Earth’s environment, we are reminded of its irreplaceable beauty. In the rock garden visitors may find clarity. As they move along the spiraling slope they feel a sensation of flight. It is not a created form, but a flow that has emerged as a result. Located here is a terrace that connects to the future.
