Nobori Building is a minimalist architecture project located in Tokyo, Japan, designed by Florian Busch Architects. By extrapolating the site’s potential and working upward, the structure transforms the limited footprint into an innovative display of vertical grandeur. This concept of upward movement is echoed in the project’s name, “Nobori”, meaning to rise or to climb. It fittingly questions conventional design approaches to building circulation. Instead of a compact, central core, the proposed solution dissolves the core, allowing stairs to weave up and down around the building’s edges. It likens entry into the building to the experience of navigating Tokyo’s network of back alleys, effectively serving as residential lobbies that bridge the urban scale. While the building may seem simple from the outside, the internal spaces are far from ordinary. Each floor is unique due to the way the stairs perforate the different levels. The vertical design allows for interstitial spaces that invite novel uses, enhancing the overall functionality of the structure. This complex layering of spaces brings to mind the intricacies of a traditional tearoom, where careful detailing transforms a minimalist environment into a rich tapestry of discovery. The structure’s façade acts as a canvas of ambiguity and multipurpose use, becoming an integral part of the load-bearing system. It demonstrates an evolving porous quality, its design flexibly responding to various requirements and desires throughout the process. The façade embodies the synthesis of multiple elements like structure, views, light, ventilation, and budget constraints, attaining an optimal compromise.
