Hudson L-House

A simple ‘L’ in custom corrugated aluminum forms a south-facing green courtyard. The 1700 square-foot house proposed on a vacant lot completes the fine urban fabric of Hudson, New York.

Material selection prioritized longevity, efficiency, and environmental performance. Powder-coated aluminum cladding, which contains 65% post-industrial recycled content (32.5% by weight) and birch plywood were chosen for their durability, low maintenance, and minimal material waste during installation. The building’s embodied carbon is calculated at 411 kgCO₂/m². The use of local builders and fabricators further lowers transportation emissions and supports the regional economy.

The building has an 18-foot unobstructed width, designed to maximize natural daylight and cross-ventilation. With a glazing ratio of only 11.8%, windows are strategically positioned to optimize views, maintain privacy, and enhance daylighting—achieved through a thoughtful mix of translucent and clear glazing.

Energy demand is primarily met through a high-efficiency ground-source geothermal system that supplies heating, cooling, and domestic hot water. The geothermal heat pump is powered by electricity from the local utility grid, which also supports lighting, appliances, and ventilation. No on-site renewable energy systems (e.g., solar PV) are currently installed. The building’s predicted operational energy use is 291 kWh/m²/year, while the total energy load is estimated at 274 kWh/m²/year.

The project’s whole-life carbon footprint totals 186,166 kgCO₂e (approximately 1,178 kgCO₂e/m²), placing it at the upper edge of high-performance benchmarks. The Hudson L-House exemplifies how thoughtful, flexible interiors can successfully integrate sustainability and community impact.
