[2] It is the current home to The William Morris Hunt Memorial Library[3] of the Museum of Fine Arts as well as to offices of Boston magazine, 829 Studios,[4] and Small Army,[5] in addition to a performance space of the New England Conservatory of Music.

It was designed in the English Renaissance Revival style in 1901 by architects Wheelwright and Haven on land purchased by the Society.

(This firm also designed the whimsical Harvard Lampoon Castle in Cambridge, Massachusetts.)

When the Hall was dedicated in 1901, thousands of members and visitors attended its ten-day opening, during which time the hall was filled with amaryllises, azaleas, Pelargonium geraniums, gloxinias, jasmine, trumpet lilies, palms, rhododendrons, wisteria, and a collection of 1,000 orchids, the finest collection gathered in America to that time.

The society's current home is the Elm Bank Horticulture Center, located on the town lines of Wellesley and Dover (2001).
