"Station entrance conceived not only for transit but as a communal area."
This project is located adjacent to the recently expanded terminus of the Osaka Metropolitan Subway's Midosuji Line, now extended. Initially, its primary function was to serve as the passageway connecting the third basement floor station entrance to the ground level and pedestrian deck. However, the design competition led to the development of this station entrance that transcends its utilitarian purpose, becoming a the public place. This underground public place, situated in Minoh City in Osaka, JAPAN with its abundant natural surroundings, provides ample room for residents to experience the sense of daily life in the city. Reflecting on historical station, such as New York's Central Station, which boasted expansive communal areas, contrasts with recent trends where rising land prices surrounding stations have led to constructions predominantly catering to commercial needs. In this context, the reevaluating station typology was essential. The project aimed to establish the semi-external space that harmonizes with the distinctive natural topography and man-made features of Minoh City, known for its waterfalls and autumn foliage. This envisioned space was designed with the intention of encouraging users to linger and stay at their leisure, promoting more engaging and community-oriented station experience.
Demonstrating an understanding of human cognition to enhance personal engagement within a space is essential.
Observations suggest that individuals, when in environments with ceiling height of 6 meters or more, tend to ignore the ceiling and exhibit behaviors similar to being outdoors. Our proposition involves the structural arrangement comprising multiple membrane roofs converging at the level of the pedestrian deck. This design creates an underground space that imparts the natural ambiance, enhanced by diffused light filtering through the membranes and the interplay of natural light and wind filtering through the overlapping layers. The verification of roof overlap was established through simulations, ensuring that precipitation, even with a 30-degree angle of rainfall from all directions, would not affect the escalator.
Given the irregular shape of the site, characterized by an approximately 45-degree angle, the staircase connecting the third basement floor to the ground level was strategically rotated to encircle the central void. Expansive landings oriented in diverse directions intersect to form a three-dimensional topography. By gazing into the central void, each floor presents the distinct perspective, carefully orchestrated to prevent the intersection of sightlines. Furthermore, situated behind the stairs ascending to the ground level, the gallery and office space are positioned. Combined with the cafe on the third basement floor, adjacent to the entrance, this arrangement fosters the environment conducive to prolonged stays at the entrance.
