Collaborated with a local team of passionate craftsmen, The Collective Arc celebrates the today's process and material technology's development that exhibits the extent of timber's capability as structural integrity, and the innovation of weaving techniques as part of Indonesia's proudly inherited form of arts. Through 3 simple architectural gestures of extruding, lifting and puncturing, the installation is able to juxtaposed a seminar and a publication highlight program. The act of lifting creates a program separation between both, while naturally create amphitheater seating stairs for seminar sessions. In addition, a cantilevered box is inserted at the volume to add differentiation between seminar speaker platform from audience, while accentuates the form of the installation as a whole.
