Descending into a valley at Grace Farms in New Canaan Connecticut, The River consists of five volumes linked together by a single curving roof. SANAA designed the project with Handel Architects serving as the executive architect. The new building provides a sanctuary, library, court, commons, and pavilion, all under an aluminum roof by Zahner. Zahner's Design Assist team was brought into the project for their expertise in engineering and manufacturing systems for custom building envelopes. The panel system provides a subtle dual curvature, and yet consists of standard-sized sheets of exterior anodized aluminum. Zahner developed the roof in close collaboration with the architects, who provided feedback and requirements for its aesthetic performance.
