Cornerstone Contracting

What Cornerstone Contracting does

Cornerstone Contracting is a privately held luxury custom home builder founded in 1992 by George Pusser and headquartered at 200 Pemberwick Rd in Greenwich, Connecticut. The company designs and builds high-end custom residences across six categories - traditional homes, contemporary homes, pool houses, barns, compounds, and city spaces - serving affluent homeowners primarily in Greenwich and Westchester County, with additional projects in New York City. Service delivery is anchored by in-house crews of construction managers, carpenters, and cabinetmakers, supplemented by pre-construction services (preliminary budgets and schedules) and construction management that brings owners, architects, and interior designers into the project early.
