Mottainai Tokyo Part 2 Project 2020 Lena Pfeiffer Columbia University | USA Mottainai Tokyo is an urban mega-structure focused on a zero-waste lifestyle. Mottainai, translating into “what a waste”, is a way of life that could enhance livability in Tokyo by creating communities of reuse. What if we were to consider Ueno train station in Tokyo not as purely a transit center but as a new urban typology specifically designed to house and maintain a bustling Mottainai community focused on zero-waste living and working? Then, a mega-scale architecture could begin to fulfil the needs of residents, businesses, and service workers in order to create a harmonious Mottainai lifestyle. The average life of a building in Tokyo is around 30 years. This project looks at the potential for recycling these materials while maintaining the style and elements of Tokyo building typologies. A range of programming focused around daily life and zero-waste living creates a library of spaces to occupy the structure. By building above the existing train station and Ameyokocho Shotengai shopping center, this project activates unused space with minimal intrusion. The structure is a catalyst within the urban fabric, encouraging interaction and participation with the broader city residents. Tutor(s)
