<sod>The home and grounds quickly proved inadequate to support a preparatory school.  In the fall of 1899, [[Theodore Chickering Williams]] and Mr. Seaver Buck, the first headmaster and the first master hired, respectively, searched for additional land. They found a large estate for sale on the current grounds of [[Marymount College, Tarrytown|Marymount College]], and purchased it with funds from Mrs. Hackley. The buildings on the estate were torn down immediately, and within a short period, construction began on the buildings that would eventually join to form the Hackley quadrangle. The first buildings constructed were Goodhue Hall and the Minot Savage building. They were in use for the first time in 1902-1903. The remaining buildings, including the Sarah Goodhue King Chapel and the Headmaster’s house, were completed by 1908.  The architectural firm of Wheelwright and Haven designed the new school buildings and Downing Vaux provided contouring and plans for the first playing field and track.<eod>
