Historic Annapolis | 99 Main Street Restoration

The Lewis team partnered with Historic Annapolis once again as the Construction Manager for the restoration of the Historic Annapolis Museum—a pre-Revolutionary, Georgian-style commercial building, located at 99 Main Street in downtown. The existing aging structure critically needed to be restored to address the lack of 21st century necessities—including the repair of the buildings deteriorating interior systems. The Lewis team recognized early in the process that the complete restoration of the existing single pane windows—initially constructed without insulation or vapor barriers—was critical to the efficiency of the replacement HVAC units. Modifications to the existing window systems included a thorough interior glazing to address the operational adjustments needed for the upcoming winter months, to prevent damage to the building, and improve the building’s ability to withstand increased humidity.

Due to the buildings historical significance—a traditional customs house built in the 18th century—considerable coordination with the Maryland Historic Trust (MHT) was also necessary throughout the four-month construction. The extensive involvement of MHT required that all associated historic materials and restoration techniques implemented by the construction team be authorized by the agency. The historic museum was also completed in compliance with all regulations and built to the Secretary of Interiors Standards—a policy that promotes historic preservations best practices to protect the community’s cultural resources.
