Exceptional commercial opportunity - Available for sale or lease, this distinctive Late Modern-style commercial building offers more than 24,000 square feet of total space on a highly visible Route 58 site. The property features approximately 11,000 square feet on the ground floor, a 3,000-square-foot mezzanine, and a 10,000-square- foot lower level with a convenient vehicular access ramp. The flexible layout provides an excellent opportunity for a wide range of commercial uses and can be readily subdivided to accommodate multiple tenants or configurations. Centrally positioned along Route 58, Riverhead's established commercial hub, the property benefits from exceptional visibility and proximity to an extensive concentration of national retailers, big-box stores, factory outlets, supermarkets, restaurants, automotive dealerships, and other major commercial destinations. The zoning permits all these commercial uses and more, offering significant flexibility for an owner-user, investor, or developer. The property is also ideally suited for recreational cannabis retail, subject to applicable approvals and regulations. Buildings of this size, quality of construction, and strategic location are rarely offered to the market.
