The W. Averell Harriman State Office Building Campus is an office park in western Albany, New York, United States that houses sixteen New York State Government office buildings. The land totals roughly 330 acres (130 ha) and over 3 million square feet (280,000 m²) of office space, and about 7,000 state employees work there. The campus was built during the 1950s and 1960s in a suburban, car-oriented style bordered by an outer ring road that cuts the campus off from the surrounding neighborhoods. The campus is flanked by Washington Avenue to the north, Western Avenue to the south, University at Albany to the west, and New York State Route 85 to the east. With its own steam generation power plant for cooling and heating (Building 17) the campus is mostly self-sufficient.
