Premier Medical / Office Building Opportunity

Take advantage of a strategic investment or owner-user opportunity in a prominent Long Island North Shore location. Situated in the heart of the medical/office corridor adjacent to Northwell Health’s John T. Mather Memorial Hospital campus, this well-maintained professional building offers excellent accessibility, strong positioning and flexible use.

Property Highlights:

Built in 1980, this Class B office/medical building features approximately 15,698 sq ft of space. 

Located on roughly 2.6 acres of land, providing ample room for parking, signage and future expansion. 

Uniquely positioned directly on Belle Terre Road – a principal corridor connecting the village and hospital campus – offering high visibility and strong client access.

Abundant surface parking (reported up to ~450 stalls according to rental listing) ensures ease of access for both staff and patients. 

Designed for medical/office use with multiple speciality practices already located in the building (e.g., surgical practice, infusion center) which underscores its suitability for healthcare, professional services or corporate office use. 

Why This Property Stands Out:

The adjacency to a major hospital campus offers a built-in professional ecosystem and patient traffic flow—ideal for medical-office users or investors targeting stable tenancy.

The size and configuration offer flexibility: user-occupants can occupy all or part while leasing remaining space, or investors can acquire and lease fully as a turnkey medical/office building.

The broad site and strong parking amenity provide rare scale in the area—much more than many small single-tenant offices.

For user-tenants, relocating or expanding into this location positions your operation within one of Long Island’s key healthcare & professional hubs.

For investors, given the building’s size, land, and location, there is significant upside through lease-up of any vacant suites or future re-positioning.
