Quadrangle Development Corporation is a United States–based real estate firm focused on the development and management of commercial and multi-family properties in the Washington DC metropolitan region. It conducts both development projects and ongoing property operations within this market. The company operates as a mid-sized firm with a regional focus, aligning its activities with urban development and property management needs. In early 2026, Quadrangle expanded its footprint by extending facilities into Virginia, signaling growth beyond the core DC area. It is involved in the Potomac Overlook project, a transit-oriented development planned for the 5.5-acre Key Bridge site in Rosslyn, Virginia, that includes apartment and hotel components. These efforts illustrate the firm's emphasis on integrated, urban-focused real estate development and management in the Washington DC region.
