Design Competition [Public Restroom Near the Akamon (provisional title)]

Organizer: The University of Tokyo

Primary Purposes

 The existing public restroom, located just inside from the symbolic Akamon on the campus of the University of Tokyo, needs to be remodeled. This brings the opportunity to consider public and health interests, both promoted by the University. Accordingly, we have decided to organize a design competition to invite ideas broadly from the students and researchers of the University for the new public restroom.
   The public restroom, although a small-scale facility, will be viewed as a symbolic facility, representing, among others, an inclusive society. The design competition seeks aspiring ideas for a facility that befits the future University campus.

Message from the Chief Judge

 We are seeking architectural designs for a public restroom that give insights into the University’s vision of the future, and of a vision of our society in the future. At a time of when everything is changing dramatically because of the impacts of the COVID-19 pandemic, we hope to pool your collective wisdom, including that of those who are not professional designers, to build a marvelous “small restroom”.

   ・(Refer to Attachments 1 ~ 4 for details)

 Entrants must fulfill the following requirements when designing the public restroom that will be built on a new site near the Akamon, thereby remodeling the existing dilapidated restroom.
     1. Architectural Conditions.

          ・Floor level of public restroom should be assumed to be the same as that of the wood deck attached to the Communication Center.
          ・Overhanging eaves of a cantilever structure from the designated site boundary are acceptable, thereby avoiding installation of posts 
              in the ground outside the designated site boundary.

               that is in keeping with the historic aspects of the Hongo Campus.
