Surprisingly, this sleek sustainable haven draws its inspiration from a Long Island barn built in the 1800’s. Completed in July 2007, the Highway House was conceived as a “modern interpretation of the Long Island agricultural vernacular”. It’s an elegant marriage of glass, western cedar siding, and concrete block interspersed with large windows that bring the outside in, suffusing the interior spaces with a lovely use of natural light.

The innovations are in the details: the house makes use of high performance Structural Insulated Panels (SIPS) that are airtight, well insulated, and quick to assemble. These panels are complemented by a 98% efficient boiler, radiant concrete floors and a geo-thermal HVAC system. The ubiquitous windows fold open during warm weather, and are composed of dual-pane low-e glass filled with argon gas, while the roof is constructed with tough, UV-resistant Kynar. Energy Star appliances and a saline pool (no chemicals!) round out a house that mixes classic lines with the latest in eco-tech.
