Exceptional large-scale commercial/industrial opportunity in Keene’s established business corridor. The Main Building of Markem-Imaje at 150 Congress Street offers an impressive 169,000± square feet of high-quality space on a substantial 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, providing a flexible layout for production, assembly, R&D, 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. Its 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. Strategically located within Keene’s commercial/industrial district, the property benefits from strong regional access and an established workforce base. A rare opportunity to acquire a landmark facility offering scale, infrastructure, parking capacity, land, and long-term redevelopment upside that is difficult to replicate in today’s market.
