150 Congress St, Keene, NH 03431

Located in Keene’s established business corridor, this large-scale commercial/industrial property at 150 Congress Street offers a substantial opportunity. The main building, formerly Markem-Imaje, provides approximately 169,000 square feet of high-quality space on a 17.7-acre parcel. Purpose-built for advanced manufacturing and corporate operations, the facility includes approximately 36,000 square feet of office space and 130,000 square feet of manufacturing/warehouse area. This flexible layout is suitable for production, assembly, research and development, distribution, and headquarters use. The building features generous ceiling heights, expansive floor plates, and 2000-amp, 3-phase power to support heavy electrical loads and specialized equipment. It is fully sprinklered and designed for operational efficiency, with multiple loading areas and convenient access points. The site offers over 390 on-site parking spaces, ample truck circulation, and excess land that may support expansion or reconfiguration. The campus-style setting delivers scale, functionality, and flexibility for manufacturing, technology, distribution, or institutional users. The substantial footprint and acreage may allow for mixed-use or residential conversion, subject to city approvals and zoning review. The size and setting create a strong opportunity for adaptive reuse, workforce housing, or large-scale redevelopment in a market where sizable in-town parcels are limited. The property benefits from strong regional access and an established workforce base.
