as space frame in reinforced concrete; the first of its kind in India,
and perhaps in the world; the 'Hall of Nations' provides an uninterrupted
exhibition area of approximately 6,700 sqm in a 82m x 82m x 27m high
truncated pyramid supported on eight points.
Each of the four 'Halls of Industries' is similar in design and is
44m x 44 m x 16m high.
Free standing coffered mezzanine floors cantilevering out of cylindrical
shafts provide additional exhibition area in each hall.
