If you’ve ever driven along the Border of Queens and Nassau County, you’ve probably seen it. It’s that massive, sprawling complex that looks a bit like a fortress of glass and brick. 1979 Marcus Avenue in Lake Success isn't just another pin on a Google Map. It’s a massive 420,000-square-foot engine for the Long Island economy. Honestly, most people just call it "the building near the Northwell headquarters," but that’s selling it short.
It’s big. Like, really big.
We are talking about a Class A office property that basically anchors the Lake Success Quadrangle. It’s the kind of place where billion-dollar healthcare decisions are made in the morning, and someone is getting a physical exam or a dental cleaning three doors down in the afternoon. It’s weirdly versatile. Most office buildings in the suburbs are struggling right now. You see the "For Lease" signs everywhere, fading in the sun. But 1979 Marcus Avenue stays busy. Why? Because it pivoted to medical use before "medical office" was even a trendy buzzword in real estate circles.
The Reality of 1979 Marcus Avenue Lake Success NY
The building is currently owned and managed by Water Reef (specifically through various entities often associated with the likes of common commercial real estate titans in the region). It sits on nearly 20 acres of land. That is a lot of asphalt for parking, which, if you’ve ever tried to park in New Hyde Park or Lake Success, you know is basically gold.
One thing people get wrong is thinking it’s just one giant room inside. It’s actually split into two main wings, often referred to as the North and South buildings, connected by a central core. This layout is a lifesaver for navigation. Without it, you’d be lost for days. The lobby was renovated a few years back to give it that high-end corporate feel—lots of stone, glass, and light. It doesn't feel like a dusty 70s relic anymore.
Who is actually inside?
The tenant roster is basically a "Who's Who" of New York healthcare and professional services. You have heavy hitters like Northwell Health—which is practically the unofficial landlord of the entire Lake Success area at this point. They use it for administrative offices and specialized clinical services.
Then there’s ProHEALTH. They’ve had a massive presence here for years. You’ll also find the ENT and Allergy Associates, LLP. If you have a sinus issue on Long Island, there is a statistically significant chance you are ending up at 1979 Marcus Avenue at some point in your life. It’s not just doctors, though. There are law firms, insurance groups, and financial advisors tucked into the upper floors.
It’s a ecosystem.
Why the Location is Actually Genius
Lake Success is an interesting spot. It’s technically an incorporated village, very wealthy, very quiet. But 1979 Marcus Avenue sits right on the edge of the action. It is seconds away from the Long Island Expressway (LIE) and the Northern State Parkway.
Think about the logistics for a second. If you’re a specialist doctor, you want to be where the patients are. This building sits at the gateway between the dense population of Eastern Queens and the affluent suburbs of Western Nassau. It’s the sweet spot. You can get here from Manhattan in 35 minutes (if the traffic gods are kind) or from Melville in 20.
The proximity to Long Island Jewish Medical Center and North Shore University Hospital is the real kicker. It creates a "medical mile" effect. Doctors want to be near the hospitals where they have privileges. Patients want to go to one area for their bloodwork, their imaging, and their follow-ups.
The "Hidden" Amenities
People work long hours here. You can’t just survive on vending machine coffee. The building has an on-site cafe that’s actually decent, which is a rarity in suburban office parks. There’s also a fitness center. But honestly, the biggest "amenity" is the tech infrastructure. Because so many medical tenants deal with massive imaging files and sensitive patient data, the fiber-optic connectivity in the building is significantly beefier than what you'd find in a standard retail strip or a smaller professional building.
What No One Tells You About Leasing Here
If you’re a business owner looking at 1979 Marcus Avenue, you have to be ready for the "Lake Success Tax." It’s not a literal tax, but the operating expenses in this village are higher than if you were just a few miles east in Garden City or Westbury. The village has its own police force and very strict zoning laws.
The upside? The prestige.
Having a "Lake Success, NY 11042" address still carries weight in the business world. It signals stability. It says you aren't a fly-by-night operation. But you have to deal with the parking lot. Even with hundreds of spaces, it gets tight at 10:30 AM on a Tuesday. The flow of patients coming in and out of the Northwell and ProHEALTH suites is constant.
Connectivity and Commuting
It’s not just about cars. The building is served by the N22, N22X, and N26 bus lines. This is huge for the administrative staff who might be commuting from Queens or further out on the Island. It’s one of the few spots in Nassau where you don't absolutely need a car to get to work, though it definitely helps. Great Neck and New Hyde Park LIRR stations are just a short Uber or bus ride away.
The Architecture and the "Vibe"
Let’s be real: from the outside, it’s a product of its era. It’s a massive block. But the management has done a lot to soften that. The landscaping is always manicured. The interior atria allow for a lot of natural light, which prevents that "cubicle dungeon" feeling that plagues so many 20th-century office designs.
When you walk into the lobby of 1979 Marcus Avenue Lake Success NY, you get a sense of scale. The ceilings are high. The security desk is prominent. It feels like a place where important things are happening. It’s professional. It’s "suits and scrubs."
Addressing the Vacancy Myths
You might hear rumors that "everyone is leaving offices." In some places, sure. But 1979 Marcus is a different beast. Its vacancy rate has historically stayed lower than the Nassau County average. Why? Because you can’t perform a physical over Zoom. You can’t do an MRI from your living room. The "medtail" (medical-retail) trend has essentially bulletproofed this property against the work-from-home revolution.
Even the office users here tend to be "essential" services—lawyers who need to meet clients in person, or insurance adjusters who need a physical hub.
Sustainability and the Future
As we move toward more green initiatives, older buildings usually struggle. However, the ownership here has been proactive. They’ve upgraded HVAC systems to be more efficient. They've integrated better waste management. It’s not a LEED Platinum skyscraper in Hudson Yards, but for a 1970s-built Long Island complex, it’s remarkably modernized.
What to Do If You're Visiting
If you have an appointment at 1979 Marcus Avenue, give yourself an extra 15 minutes. Not for the driving, but for the "finding the suite" part. The building is long. If you park at the wrong end, you are going to get your steps in for the day.
- Check the Wing: Confirm if your doctor is in the North or South portion.
- Security: You usually have to sign in or show ID at the front desk, especially since the pandemic changed how healthcare facilities manage foot traffic.
- Food: If the on-site cafe is packed, you are a two-minute drive from the retail clusters on Union Turnpike or Hillside Avenue.
The Verdict on 1979 Marcus Avenue
It’s a powerhouse. It’s the backbone of the Lake Success professional community. While other buildings are being converted into apartments or standing empty, this one just keeps humming along. It’s a testament to the idea that if you have a great location and you cater to the healthcare industry, you can survive almost any economic shift.
It’s not just a building; it’s a landmark of the Nassau-Queens border.
Actionable Steps for Interested Parties
For Prospective Tenants:
Contact the leasing agents through the Water Reef management portal. Be prepared to provide a detailed use-case, as the building is increasingly selective about maintaining a specific tenant mix (prioritizing medical and high-end professional services). Check the current floor plans for "contiguous space" if you need more than 10,000 square feet, as those larger blocks are becoming rarer.
For Patients and Visitors:
Always check the specific suite number before leaving. Many offices within 1979 Marcus Avenue have satellite locations elsewhere in New Hyde Park. Use the Marcus Avenue entrance for the most direct access to the main parking areas.
For Real Estate Investors:
Keep an eye on the surrounding developments. As the Northwell Health "campus" continues to expand across the street and in nearby blocks, the valuation of 1979 Marcus Avenue is tied directly to the health of the regional medical system. It’s a bellwether for the "Medical Office Building" (MOB) asset class on Long Island.
For Commuters:
If you're using the LIRR, use the New Hyde Park station and catch the N26 bus. It’s the most efficient "last mile" connection to the building during peak morning and evening hours.
