ABSTRACT
Growth in the Megastructure of Metabolism is growth of living organisms, which develop their structures from within through the existence of a characteristic center. However, the growth of the 'space-frame' structure is similar to the growth of crystals, which form their homogeneous structure through the accumulation of similar parts. The representations of 'growth' in Kikutake's and Tange's 'mega-urban structure' differ from each other, which can be traced back to their different interpretations of 'closed' and 'open' forms. The two curved residential blocks enclosing partially an open space at the center in the Massachusetts Institute of Technology (MIT) Boston Harbor Project, 1959 have transformed into the 'linear-parallel-radiating' pattern. One can understand Tange’s ‘closed form’ represented in the curved lines, which encloses a void at the center, and his ‘open form’ represented in the straight lines that has no potential to enclose a void.
