A historic, cream brick house with arched windows and ornate roof details is under renovation, embracing principles of conservation. Scaffolding and yellow safety barriers surround the entrance, and gray steps lead up to dark double doors. Leafless trees and green grass in the background highlight a setting that subtly supports environmental protection.
Arched wooden door with a glass window, set in a stone wall with ivy climbing on both sides. The doorway has a light stone trim and leads into a building dedicated to conservation. Reflections of trees are visible in the window, evoking a sense of the outdoors and underscoring the importance of wildlife conservation and environmental protection.
Several ornate, weathered wooden pieces with circular star carvings and blue tape labels numbered 12, 13, 20, and 21 rest on a concrete floor. Yellow tools and metal parts are visible in the background, suggesting a workshop or restoration setting where conservation efforts may be at play to preserve these artifacts for environmental protection.

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.
