The LEED Silver adaptive reuse of the historic Annapolis Post Office building provides much needed office space for the State of Maryland in the heart of the capital’s Legislative Complex. The design retains the integrity of the historic architecture while while creating a 21st-century office environment that is accessible, flexible, and sustainable. The 25,000 sf Georgian Revival style historic building required all new systems, extensive repairs to the building envelope, and interior reconfiguration to support multiple agencies. Laser scanning technology and destructive testing of the building envelope supported an understanding of the building condition, construction, and required modifications to accommodate the intended use and improve building performance.
