THE SEAMLESS INTEGRATION of PPA Conservation with our architectural studio means that the expertise in historic design and building science is shared to mutual benefit. Led by Lewis Gleason, our forensic approach to architectural conservation combines thorough archival research, hands-on analysis, and the latest design and construction technologies.

Conservation best practices also inform new construction; our conservation team works in concert with architectural designers to identify and redress any potential structural weaknesses during design phases, provide on-site QA/QC during construction administration, as well as guide our projects through comprehensive vetting by the Landmarks Preservation Commission and other regulatory agencies.
