Walters Art Museum

Hackerman House

Modernization of a Historic Mansion and Gallery Space

Part of the Walters Art Museum’s five-building, historic complex of gallery, conservation, and administrative spaces, the circa-1850 One West Mount Vernon Place provides a distinctive architectural backdrop for the museum’s world-renowned collections. The Greek Revival mansion includes a glass-filled conservatory, a Tiffany glass skylight, and a library featuring mahogany paneling and recently discovered plaster panels dating to the home’s original construction.

Mueller provided engineering services for the $10.4 million renovation of the three-story Hackerman House portion of One West Mount Vernon Place. The project encompasses approximately 19,300 SF of space and involves a comprehensive upgrade of the MEP systems, carefully installed within the historic structure. Two air handling units, exhaust fans, hot water boilers, pumps, humidifiers, variable air volume terminal units, ductwork, piping, power, lighting, and a new building automation system have been included.

A separate boiler was provided to serve the entire One West Mount Vernon Place during the renovation. Mueller also engineered a first-floor renovation to the nearby 100 West Centre Street building to accommodate the temporary relocation of Hackerman House personnel. Mueller has served the museum for nearly 25 years and previously provided MEP engineering for the renovation of approximately 6,000 SF within the Hackerman House and adjacent carriage house structures to accommodate semi-permanent exhibit space. These upgrades included modifications to air devices, sprinkler heads, lighting fixtures, and receptacles; and the replacement of the humidifiers serving the air handling units.

"We are approaching the refurbishment of Hackerman House as if the building itself were a work of art…The five buildings that make up the Walters Art Museum are the largest and most complex artworks in our collection. We’re going to be devoting more intellectual firepower to the buildings themselves."
Julia Marciari-Alexander
Director, Walters Art Museum
