The clubhouse opened on May 23, 1887. Land, building and furnishings cost $306,669.25. In 1902 a major renovation converted the original Victorian interiors to Edwardian and a partial sixth floor containing a laundry and other staff quarters was added to the original five story structure. In 1910, Charles Wetmore of the firm of Warren & Wetmore, a member of the Association, was engaged to plan an addition which was completed on March 16, 1911, at a cost of $175,556.76. The addition, in an exterior style sympathetic to the original, added several private dining rooms as well as the magnificent Jacobean-style paneled reading room on a new mezzanine level.
