The school moved to its final location in 1917, at Vanderlip Hall, a building Vanderlip constructed in 1916 bordering Albany Post Road (current U.S. Route 9). The building was designed for classes of ten, to accommodate 120 children total. It was situated on Beechwood's parkland designed by Frederick Law Olmsted for the Vanderlips. Throughout the school's history, students were open to wander the woodlands and gardens, utilize the lawns and tennis courts, and swim in the Olympic-sized pool. There were always farm animals nearby for the children to see and play with and a circus carousel to ride on. The school had a gymnasium class, amateur theater group, folk singing, a swimming pool, and an economic forum. Frank Vanderlip had spent about $500,000 on the school ($ in ), and he remained chairman of the school board of trustees until his death in 1937. Regular art exhibits were held at the Scarborough School, including a sculpture exhibition in the Italian garden at Beechwood, which included works by Jose de Creeft, Jason Seley (a longtime professor of sculpture at Cornell), and Richard Stankiewicz.
