Abstract The proposal design model of a pavilion is the direct result of an extensive exploration of various plastic sheets and their properties.the shape of the pavilion comprises of a double curved surface (which was supposed to be achieved as per the design brief ).The plastic sheets,namely-polycarbonate sheet,acrylic sheets and polypropylene sheets,were subjected to hot air,provided by a heat gun and were placed in a carefully planned apparatus.This apparatus contained of numerous nails where heights was adjustable.the nails were placed in unique arrangement and gave unpredictable shapes to the sheets (placed on them)on heating.Polycarbonate turned out to be the most durable and easily mouldable material and was explored further various iterations were applied on the polycarbonate sheets which resulted in prototypes having geometries varing from being locally doubled curved to globally doubled curved.The final form is the result of grasping the nature of the material and understanding the possibilities of the apparatus.
