| shigeru ban: paper loghouse in june 1995, a great number of people were still forced to live in shabby tents in parks nearby their destroyed houses even six month after the earthquake in kobe. ban's solution was a cheap and simple structure that could be build by anyone. the foundation was made of sand-filled beer cases, the walls of paper tubes and the ceiling and roof of tent material. the roof and the ceiling were kept separate in summer to allow air to circulate and closed in winter to retain warm air. they were easy to recycle after use, easy to transport, easy to store and the paper tubes could be made on site. 'the good thing about paper tubes is that they are readily available in various thickness and diameters. the weight they can support depends on these two things. theoretically, I can make buildings a few stories high, but I haven't yet been given the opportunity,' says ban. shigeru ban is a pioneer of paper tube structures (PTS), he investigated the substance and found that not only could recycled cardboard be molded into load-bearing columns, bent into beautiful trusses and quickly assembled, but it could also be made waterproof and fire resistant. in the space between the paper tubes, self-adhesive waterproof sponge tape was applied to both sides.  waterproof - see the short video clip. --- the units occupied 16 mq each and had an 'acceptable' appearance. the beer cases were rented from the manufacturer and were also used to form steps during the construction process. even in these circumstances of great need, ban's ever-present sense of humor was evident in his description of his choice of 'kirin' beer crates over those of a rival company, because their yellow color harmonized better with the brown of the paper tubes.  beer crates - see the short video clip. --- shigeru ban: paper church a slightly different construction was used to build a church. as a result of the earthquake, the takatori church in kobe burned down. the paper church has been constructed in only 5 weeks by 160 church volunteers. 'it didn't allow a long design period and tests so the structure used the techniques of the paper architecture which had been developed in previous projects. it was also important that it was low cost and could be assembled safely by volunteers without heavy machinery.' shigeru ban says. 'the building was rectangular in form, 10 metres by 15 metres, with an interior oval capable of accommodating 80 seats formed from 58 paper tubes, each one 5 metres in length, 330 mm in diameter, with a thickness of 15 mm. along the long axis of the oval the tubes were closely spaced to form a backdrop behind the stage, for the altar and as well as forming a backspace for storage. along the front axis of the oval, the tubes were placed at a wider spacing so that when the front sashes were open, there would be a continuity between the interior and exterior spaces. his formed a fantastic space where the entrance sequence from the corridor to the main space could be experienced and where the eyes were drawn up towards the ceiling. ---  back to the article --- ---  ------- monthly designboom newsletter
