Keen Development Corporation is a real estate development company specializing in historic rehabilitation and adaptive reuse.

Keen has a long-standing dedication to the creation of attractive and affordable housing. Many Keen sites provide mixed-income residential options to Massachusetts cities and towns. Over the past 20 years, Keen has developed nearly 3,000 units of housing, employing both government funding programs and conventional financing. The company is well known for its public service commitment, frequently joint venturing with community-based organizations and otherwise participating in public/private partnerships.

Keen is perhaps best known for a number of award-winning historic preservation efforts, including the Baker Chocolate Factory, Kennedy Biscuit Lofts, and Sumner Hill House. However, the firm brings the same commitment to design excellence to new construction sites such as West End Place in Boston and Battle Road Farm in Lincoln.

In addition to its extensive housing experience, Keen has developed sites for institutional and commercial use ranging from educational facilities to childcare centers to biomedical research laboratories.
