Enoch Pratt Free Library

A Multi-Phase Renovation of a Historic Downtown Library Building

The Enoch Pratt Free Library is the oldest public library system in the country, and its flagship Central Library building is one of Baltimore’s most cherished historical landmarks. Initially built in 1933, it houses nearly two million books and a special collection of rare books, maps, and other documents dating back to the 17th century. The Art Deco-style building features a majestic central hall, ornate ceilings, murals, large display windows, and other elegant architectural details throughout the nearly 300,000 SF building.

Clearly showing its age, both in terms of structure and systems and in its ability to accommodate the needs of 21st-century library programming, the Pratt embarked on long-planned renovation to modernize its systems, increase energy efficiency, restore the Central Hall, and create new and expanded spaces for its employees and the visiting public.

The modernization and renovation of the historic Central Building involved the design and engineering of new HVAC, electrical, plumbing, fire protection, security, data, and communications systems. All existing heating, ventilating, and air conditioning equipment was removed and replaced. New custom factory-fabricated air handling units are on the roof. Other equipment is in the existing basement and penthouse mechanical rooms.

The new Central Library has attractive public spaces that encourage study, discussion, creativity, and collaboration. The restored Central Hall serves as the Library’s “Town Square” where people can gather to hear authors talk about their latest books, discuss important issues, and enjoy performances in a hall enhanced by an up-to-date sound system, stage, lighting, and audio-visual equipment.

"In the early design phases, Mueller and BBB’s extensive coordination efforts to verify existing conditions helped confirm our assumptions for routing all new utilities within the historic fabric. This successful collaboration is evident in this transformational renovation."
