While the building of the New Chapel was the major building project of the 1880s, during the 1890s a wave of long-delayed construction projects were completed. Joseph Coit was responsible for a major enlargement of the Big Study; a complete reconstruction of the Old Lower School, renamed “Middle”; and the Whitney Annex joined to the Old Gymnasium by Lower School Pond. Also, several new buildings were erected in this era: Alumni House, Sheldon Library, and the New Upper School. This wave of construction led the School to seek advice on an overall master plan from the firm of Olmsted Brothers, founded by Frederick Law Olmsted, designer of Central Park in New York. The Olmsted Report of 1898 stands as a major school document in that it offered advice on how new construction was to be situated within the School so as to grow and develop according to a master plan.
