Interface Studio — The Urban Infill House 001 + 002 is a pair of LEED Platinum houses constructed for $100 per square foot in Philadelphia. The project uses SIPs and includes a solar-powered hot-water heater and a gas-fired furnace, among other efficiencies. Marion Weiss liked “the fact that you could pull off something with that kit of parts and achieve something pretty singular and memorable on that budget.”
