Balancing shifting volumes and planes along sloping topography, the Spring Mill House’s wooded site with pond was favorable because of the ability to submerge part of the structure into the hillside. Its indoor spaces are flooded with natural light from abundant glazing, promoting connectivity with nature. “Indoor and outdoor flow is seamless, providing an environment where spaces for health and wellness are equally integrated with spaces for work, gathering, relaxation, and contemplation,” the project application reads.
Intimate spaces like the bedrooms and office are tucked away on a separate level from the larger areas designed for gatherings. A bar and game room on the basement floor are ideal for hosting. The blended interior and exterior spaces unite different areas of the home at varying levels, including the home’s volleyball/gym space; a year-round swimming pool that opens to the outdoors; and a workout space and yoga room.
Large sliding glass panels open the interior spaces to provide fresh air, minimizing HVAC use. With sustainability a priority, the home utilizes a geothermal HVAC system with radiant in-floor heating, solar panels, green roof systems, a Tesla Powerwall, thickened walls, and a rainscreen wall cladding system.
