An exceptional investment opportunity in one of Keene's most recognizable historic commercial buildings. Formerly known as the Miller Forge Building, this beautifully renovated three-story mill building offers approximately 26,708 square feet of office space on 0.80 acres and is fully occupied with a diverse mix of local businesses operating under month-to-month and short-term leases, providing flexibility for future ownership. Originally constructed in 1920, the building blends historic character with modern functionality. Many offices and common areas retain their exposed beams, hardwood floors, and industrial mill charm, creating an attractive workspace for today's tenants. The property offers both elevator and stair access, parking for approximately 60 vehicles, and electricity is included in the tenant rents. Located just minutes from downtown Keene, this property benefits from a vibrant business community, walkable Main Street, and convenient access to restaurants, retail, professional services, and major commuter routes. Keene serves as the commercial, educational, and cultural hub of the Monadnock Region, making it a desirable location for businesses and investors alike. 103 Roxbury Street may be purchased individually or as part of a three-property commercial portfolio, offering investors the opportunity to acquire a diversified collection of fully leased commercial assets.
