Envelop brings awareness to the issue of flooding through the simulation of Sumbersion. The effect is created by using various layers of polyurethane sheeting which are suspended from multiple points. Our proposed installation’s ethereal layers of plastic sheeting mimic the rising tide of water as the occupant wades through the narrow channels created within the form. Eventually, the delicate seamed openings in the layered plastic drapery become completely enclosed and force the occupant to dip beneath the surface. Once the occupant is completely submerged, they are washed with light and able to discover the movement of the volumetric form below.
