DESCRIPTION

       The  Nakagin  Capsule Tower was demolished in 2022, but this version will continue to grow
       forever.

       Constructed in 1972, the building was composed of small prefabricated  rooms  attached  to
       the  two  central towers.  The capsules were intended to be mass produced and replaceable.
       Utilities and fittings were installed before the capsules were shipped to the site.
