Diamond Hill is a single-family residential subdivision comprising 124 homes located along Diamond Hill Road in Berkeley Heights. The parcel was purchased from a private trust, the project involved securing municipal approvals, and installation of roads, water, sewer, and utilities before constructing the homes between 1982 and 1987. Designed by Samuel Abate, the houses average 2,150 square feet and sit on individual lots of approximately 0.78 acre. Each unit features a one-car garage, basement, and full kitchen, and benefits from proximity to Governor Livingston High School and Union County transit services.
