House Zero

House Zero is a field trial project using ICON’s Exploration Series 3D-printing technology. The 2,350sf single story, three-bedroom home is a standalone single-dwelling unit designed for flexibility to respond to everchanging domestic requirements. Its design is tailored to the innovation of the proprietary concrete wall 3D-printing system, which is a software-controlled, additive manufacturing method that results in significant construction efficiencies. GNA coordinated with both the architect and ICON to develop the structural system. Fully grouted columns of different cross-section geometries and plywood shear walls are embedded in ICON’s 3D-printed Lavacrete wall to support the wood roof framing, which is split into two roof planes to provide clerestory windows and higher ceilings in the home’s public areas. Glulam posts bridges the gap between the two roofs for a clerestory. The cantilever columns work together with bond beams to offer lateral stability to the whole structure.
