SEAT is composed of approximately 300 simple wooden chairs arrayed and stacked in a sine wave surface drawn into an agitated vortex rising from the ground. It formalizes the transformation of chairs from detached useable objects into structural and spatial components of an ambiguously occupiable edifice. It’s intended to be legible and readable as a collection of individual seats, but when approached, visitors realize that sitting down in any one of them amounts to a deliberate act of occupation; a temporary social contract to redefine their perception of sitting embodied as architecture. The structure is zoned by rotational differentiation in groups. Chairs around the immediate periphery are rotated for outward observation of the city and the surrounding neighborhood. At the base of the vortex, chairs turn inward to create an intimate, compressive space for visitors to converse and regard the upward flow of chairs transcending their function. Chairs suspended above ground between these zones re-constitute the role of the seated object as one that can also play as structure, decoration, and enclosure.The chairs are additively assembled through a modified “corbelling” process achieved by sequentially attaching chairs beginning at the edges and corners working towards the center. The chairs are resiliently connected to each other via simple lag bolts, clamps, and screws that are hidden from view. Parametric detailing manages tolerances and connection pecifics of this hardware. Moment and shear forces are transferred through the entire structure as a continuous diaphragm ultimately loading at the vortex center and the seated periphery on the ground. A number of base connections, platforms, or struts also augment structural stability and anchorage. Some cantilevered extensions exist to create overhanging enclosure, but are minor in actual weight aloft. Redundancy in material and connection allow for stability, flexibility, and safety overall.
