This exceptional commercial opportunity offers ±5,815 square feet of versatile, high-ceiling space in the heart of Winthrop's Center Business District along Putnam Street — one of the town's most active and visible commercial corridors. The space features impressive 10-foot wall heights, solid brick and masonry construction, and gas forced-air HVAC with central air conditioning, delivering both the structural character and mechanical reliability that today's tenants demand. The floor plate is fully subdividable, making this an ideal fit for a single-user occupant or multiple tenants seeking smaller suites in a prime downtown location. The property is well-suited for a wide range of uses including retail, professional office, fitness/wellness, salon or spa, food and beverage, or any service-based business concept looking to establish a presence in a dense, walkable coastal community just minutes from Boston. Offered on a Triple Net (NNN) basis at $17.00 per square foot annually, with flexible lease terms of 3 to 5 years and renewal options available. Space is available for immediate occupancy. The location provides outstanding pedestrian access, with restaurants, banking, the post office, and daily services all within walking distance. MBTA bus service connecting directly to Boston further enhances the site's accessibility for both employees and customers. With limited available commercial inventory in this tightly held market, this represents a rare chance to secure a prominent and flexible footprint in downtown Winthrop.
