Prefabrication experiments - 76 - Shigeru Ban's Paper Log Houses

Throughout history, war, natural disasters and political uncertainty have all caused significant needs for temporary housing. The displacement of large populations for economic reasons such as wartime work camps or the need to quickly restore shelter in difficult conditions encouraged the development of mobile housing systems.  In architecture, these turbulent conditions seem to create productive conditions to explore and innovate. Alavar Aalto’s emergency shelters, Buckminster Fuller’s Dymaxion Deployment Units or Herbert Yates’ plydom houses speak to an illustrious body of architectural work and knowledge that stemmed from hardship and contributed to forging modern architecture's social origins.

The work of Shigeru Ban displays this modern heritage of invention through need. Shigeru Ban is a Japanese born architect who studied at the Southern California Institute of Architecture and Cooper Union in the United States during the late 1970s and early 1980s.  His interest in housing systems was inspired by his modernist ingrained education and a reverence for John Hejduk’s experimental houses. Moreover his consideration of relatively cheap, ready made and raw materials informed his designs for simple, quickly assembled post disaster dwellings. 

His use of vertical cardboard struts for the Paper Log Houses showcased the paper tubing as a modestly transformed and manufactured material characterized by its low embodied energy and its versatility. The 16 meter square floor area shelter relates Ban’s design to other small house experiments such as the Daiwa midget house in Japan or the Australian iron houses. Both strived to offer significant shelter swiftly with relatively new production methods.


Designed for disaster relief following the earthquake in Kobe in 1995, the paper log houses displayed new methodologies, which were then applied to other functions. Shigeru Ban’s paper house, paper church and Rwandan emergency shelters employed similar cardboard struts sealed to resist inclement weather. Waterproofing films, polyurethane and acrylic paints can be used to improve cardboard’s material properties, allowing it to become a durable and low cost option for construction. The transient nature of disaster dwelling lends itself to this type of material investigation. Along with his paper log prototypes, his other experiments such as the furniture houses attempt to rationalize living spaces, offer functional agility and express simple and straightforward construction techniques.
