This vacant former animal-research facility presents a unique opportunity to acquire a specialized campus in Mansfield Township, Warren County, New Jersey. The property consists of five buildings totaling approximately 31,900 square feet situated on approximately 7.44 acres with extensive paved road frontage. Originally designed for animal research, holding, and quarantine operations, the improvements include specialized infrastructure that can support a variety of future uses. The buildings feature large adaptable interior spaces, sealed and drained floors, extensive plumbing systems, climate-control infrastructure, and heavy mechanical ventilation with roof- and wall-mounted exhaust systems. Multiple rooms and wings provide flexibility for reconfiguration, while drive-in and overhead-door access enhance operational functionality. The site is further supported by private well and septic systems, public electric service, and a fenced and gated campus environment. Positioned in a rural setting and surrounded by farmland and preserved open space, the property offers privacy, operational separation, and room for a range of specialized commercial, research, agricultural, veterinary, laboratory, or controlled-environment uses. An on-site colonial farmhouse currently suited for office use provides additional administrative space. The property is being offered vacant, allowing an owner-user or investor to reposition the asset for its next chapter.
