Our Company

Quadrate Development was founded in 1984 by brothers with a dream. The founder’s Antonio and the late Egidio (“Gino”) and Robert D’Agostini had a vision to build the finest industrial/commercial facilities in the industry. Incorporated in 1994, Quadrate Development, LLC and its related entities were created to purchase and develop real estate primarily in Southeast Michigan. The firm currently owns and manages more than 50 industrial and commercial properties in southeast Michigan, ranging from 2,600 square feet up to over 115,000 square feet. The space is leased by a variety of tenants who range from small businesses with less than 20 employees to publicly-traded companies.

Quadrate Construction, LLC founded in 2006 was developed not only to handle its own projects, but to perform the same services for third parties. Quadrate Construction, LLC’s mission statement is simple: to provide the same level of service it expects for its own portfolio of properties. Quadrate Construction, LLC is a full-service design-build firm capable of handling any size commercial or industrial project from conception to completion. The firm, coupled with its external partnerships that have been developed and sustained by the D’Agostini family since the mid-80s, offers dedicated and knowledgeable professionals who apply vast experience in real estate development and building construction. The company’s staff handles all aspects of property development and real estate management.
