In his work for the town of Princeton and the College of New Jersey, John Notman demonstrated the range of his talents and interests. His earliest commission was the landscaping of Fieldwood, the estate of Judge Richard Stockton Field, who was involved in the founding of Princeton's short-lived law school. In 1846-7, Notman also designed the building used by the law school, now known as Ivy Hall. This small structure has since been used as the first home of the Ivy Club, and is now used by Trinity Church. In that same period, Notman also designed the Refectory for the Princeton Theological Seminary.
Following his work on the College's Chapel, Notman returned to Princeton to build several residences. These included the John P. Stockton House, later renamed Lowrie House (1848-9), the Springdale House (ca. 1851-2), Prospect (1851-2), and Fieldwood, later renamed Guernsey Hall (ca. 1853-5). He also built the Second Presbyterian Church (1848-9).
Notman's final work in Princeton was the remodeling of Nassau Hall following the fire in 1855. While his Belvedere towers no longer stand at the sides of this building, the entrance, with its heavy rusticated arch, still bears the mark of Notman's style.
