Historic renovation and restoration work requires a delicate balance between preservation and modernization so that the historic spaces can continue to serve a useful function. It takes construction management at its highest level to satisfy both the preservation and functional needs that historic spaces require. John O'Hara Company has developed working relationships with the best artisans and craftsmen in the region who, along with O'Hara's own expert carpenters, can accomplish even the most exacting of restoration work. 

Restoration is only truly effective if the space or structure can remain functional in today's world. The real challenge in historic structures is to add the electrical, telecommunications, climate control and life safety systems that today's buildings require without altering the structure so that the fabric of the space is irrevocably compromised. Working with the design and engineering team, John O'Hara Company has a proven record of success in finding the means and methods to blend modern systems into historic structures without destroying any significant architectural features or compromising the ambiance of the space. The firm brings a passion, commitment and professional expertise to historic renovation and restoration that result in projects that meet the requirements of both the past and the future.
