Founded in 1991, Sea-Dar Construction believes building trust is as important as building exceptional homes. With offices in Boston, Cape Cod, New York, Greenwich, and the Hamptons, Sea-Dar has earned a reputation for excellence in architecturally complex, luxury residential construction.

Sea-Dar's experienced team provides comprehensive construction management, guiding each project from conception to completion with meticulous attention to detail.
