Specialization in Historic Preservation projects began with early work on various cultural, educational, and religious institutions, in addition to residences of historic significance. The firm's skill in preserving the integrity of historic buildings and sites while creating related adaptive reuse programs is apparent in its ongoing design work in all these areas.

While working with the special considerations specific to providing conservation environments for museum collections, the firm has honed its expertise in technical issues related to historic preservation and adaptive reuse, often in conjunction with the retrofitting of environmental control systems-a complex and demanding combination.

Notable projects of this type are The Albany Institute of History & Art in Albany, NY; The Frederick Law Olmstead Historic Site in Brookline, MA; The New Bedford Whaling Museum in New Bedford, MA; The High Lawn Farm Estate in Lee, MA; St Paul's Cathedral in Boston, MA; and the Ames Courtroom at Harvard University in Cambridge, MA.

The firm has assisted clients in writing successful proposals for Massachusetts Preservation Project Fund (MPPF) grants and has coordinated with the Massachusetts Historical Commission (MHC) on several Preservation Restriction Section 106 reviews.
