In height, it is tied with Harbor Towers I as the 37th-tallest building in Boston.

The building was the first development in Boston of the New York–based real estate firm Rose Associates, led by Daniel Rose,[3] who went on to develop One Financial Center and Boston Wharf.

The original owners were Rose Associates (New York), Central & District Properties (London), and anchor tenant Keystone Custodial Funds.

To that end, Rose engaged architect Pietro Belluschi, a leader of the Modern Movement in architecture, to design the building's notable exterior, featuring distinctive rounded corners and grooved façade.

Belluschi worked with the architectural firm of Emery Roth & Sons, who developed the construction drawings and interiors.
