Architectural Conservation of Historic Structures.
Knowledgable, practical conservation of historic fabric.


The conservation of existing historic fabric is the defining component of any restoration project. Our broad experience with diverse historic building materials including masonry, timber frame construction, finishes and plaster, metals and glass, as well as wood and millwork, insures their harmonious incorporation into the new work. Further, a proper understanding of the architectural significance of the existing historic fabric can furnish the best guide for the project itself, pointing the way to the most efficient and satisfactory project outcome.

Historic Structures is pleased to work with clients who seek deft and considered incorporation of existing historic fabric in their project. Our knowledgable, creative and respectful approach to conservation of original work can produce the most practical solution for your project as it has for so many others. We are glad to hear about your significant historic restoration project:
