Inspired by a bike rack, Palo Alto Architect, Joseph Bellomo, has designed a sustainable, off-grid prefab home called the House Arc. This curvaceous modular home by Palo Alto architect, Joseph Bellomo, is joining the ranks of affordable, modular housing. Dubbed the House Arc, Bellomo was inspired to create the home after the success of his modular bicycle rack design, the Bike Arc  designed to provide efficient storage space for bicycles. Made from tubular steel armature, the home is placed above ground on concrete piers or a wood deck and then sheathed in translucent polycarbonate plastic. Bellomo estimates that it could cost $100,000 for an 800 square foot prefab home. His design lends easily to additions and extensions of the home as needed. The Palo Alto Architect responsible for the  modular prefab bike parking structure Bike Arc Joseph Bellomo has now applied the same construction techniques to create a similarly modular system for a prefab house that he calls the House Arc.
