This is a residential and tenant project planned on a site with a fantastic view in Tokyo. The structure consists of the tenant spaces from the basement to the second floor and residential units from the third to the fifth floor.

Leveraging the unique characteristics of the site that offers outstanding views, the design aimed to create residences that interact with the city by providing large openings and spacious terraces.

Due to the limited site area, the building must maximize its footprint, pushing the floor area ratio to its limits. The project faces constraints like height restrictions and parameters such as sunlight regulations and required ceiling heights for living spaces in a high-density location. To address these constraints, the roof slab is designed in a folded plate structure that extends gracefully towards the landscape in a cantilever-like shape. The roof’s shape was determined through simulations to meet both of the mentioned parameters.
