New York City’s skyline is basically a permanent construction site. If you’ve walked past Grand Central lately, you know exactly what I’m talking about. The old Hyatt Grand Central—that dark, glassy box from the 80s—is finally on the chopping block. In its place, we’re getting Project Commodore, better known as 175 Park Avenue.
Honestly, the sheer scale of this thing is hard to wrap your head around. We are talking about a 1,575-foot supertall that will effectively reset the hierarchy of Midtown East. But if you’re looking for a 175 Park Avenue construction update and wondering why there aren't steel beams flying into the air yet, the answer is a mix of high-stakes financing and some of the most complex engineering ever attempted in Manhattan.

Where things stand right now
It is January 2026. If you were expecting the building to be halfway up by now, you’re not alone, but that’s just not how these mega-projects work. Right now, the project is moving through the final "red tape" phase. Federal environmental reviews and various permitting milestones are scheduled to wrap up this month—specifically around January 8th to 9th, 2026.
Demolition hasn't fully leveled the Hyatt yet. Why? Because the developers, RXR and TF Cornerstone, are playing a very calculated game with timing and money.
Recent reports, including some chatter from RXR’s CEO Scott Rechler late last year, suggest they are finalizing a massive financing package. We are talking about a $6.5 billion price tag. To put that in perspective, One World Trade Center cost about $3.9 billion. This is officially one of the most expensive buildings ever conceived.
The $5 billion federal gamble
You might have heard the rumors about federal loans. It’s true. The developers have been in talks to secure up to $4.8 billion in federal loans through programs designed for transit-oriented development. Since the tower is literally being built on top of and around Grand Central’s infrastructure, it qualifies for a very specific type of government help.
Banks are currently terrified of office buildings. You know the drill: "work from home" changed everything. However, the "flight to quality" is real. Companies don't want mediocre offices anymore; they want the absolute best. 175 Park is betting $7 billion that it can be the "best."
What’s actually happening on-site?
- Final Permitting: The Federal Transit Administration (FTA) is finishing the NEPA review as we speak.
- Transit Prep: Before the tower goes up, the subway and train infrastructure below must be reinforced.
- Demolition Staging: Most of the work is internal right now—stripping out the old Hyatt hotel to prepare for the heavy-duty structural removal later this year.
Why the engineering is a nightmare (in a good way)
Building a 1,500-foot tower next to a 100-year-old landmark is a logistical mess. The site is restricted by the 42nd Street subway station and the Metro-North loop tunnels. Basically, 66% of the ground is "untouchable." You can't just dig a big hole and pour concrete.
The architects at SOM (Skidmore, Owings & Merrill) came up with a wild solution. The building doesn't sit on a traditional base. Instead, it uses a series of "mega-columns" and a latticed steel frame that gathers at the bottom into two massive bundles. It looks like a flower blooming out of the sidewalk.

This design isn't just for aesthetics. It’s a structural necessity to avoid crushing the train tracks below. It’s honestly kind of brilliant. The "inverted taper" at the base creates 24,000 square feet of elevated public space. You’ll eventually be able to walk up a grand staircase from 42nd Street and hang out on a terrace that overlooks the Pershing Square Viaduct.
175 Park Avenue construction update: The 2026-2030 timeline
Don't expect the skyline to change tomorrow. If the current schedule holds—and in NYC, "holds" is a generous word—we are looking at a multi-year slog.
- Mid-2026: This is the expected "hard start" for major demolition and foundation work. Once the permits clear this month, the heavy machinery moves in.
- 2027-2028: The "rise." This is when the steel lattice will actually become visible to the tourists at Grand Central.
- 2030-2032: Completion. While early estimates said 2030, most industry insiders are now eyeing 2032 for the grand opening.
The "Chrysler" Problem
There is a lot of drama regarding how this building affects the Chrysler Building. If you stand on Lex, 175 Park is going to look like it’s swallowing its neighbor. It’s roughly 500 feet taller than the Chrysler.
Preservationists have been vocal, but the city’s Midtown East Rezoning plan was designed specifically to allow this. The trade-off is that the developers have to spend over $500 million on transit improvements. We're talking a brand-new 5,400-square-foot transit hall, new subway entrances, and better connections between Metro-North and the LIRR.
What most people get wrong about this project
People see "new office building" and think it's a waste of space. But 175 Park isn't just an office. It’s a hybrid. It will house a new 200-room Hyatt hotel at the very top (floors 65 to 83).
Also, it isn't a "pencil tower" like the ones on Billionaires' Row. Those are skinny residential sticks for the ultra-wealthy. This is a massive, high-capacity commercial engine. It’s designed to hold thousands of workers, which Midtown desperately needs to stay relevant as a business hub.
Practical steps for the curious
If you’re a skyscraper nerd or just a local commuter, here is what you should keep an eye on over the next few months:
- Watch the 42nd Street sidewalk: When the scaffolding starts expanding and the heavy sidewalk bridges go up, that’s your sign that the internal demolition has moved to the exterior.
- Check the NYC Department of Buildings (DOB) portal: You can search for 175 Park Avenue to see the specific permits issued. Look for "Full Demo" or "New Building" status changes.
- Visit the transit hall site: Some of the earliest work will be the street-level modifications near the Lexington Avenue entrance of Grand Central.
The "Project Commodore" era is officially beginning. It’s going to be loud, it’s going to be expensive, and it’s going to be the most significant addition to the New York skyline since One Vanderbilt. Just don't expect it to happen overnight.
For those following the progress, the next big milestone to watch for is the official announcement of an anchor tenant. Once a major bank or tech firm signs a lease for 500,000 square feet, the cranes will start moving faster than you can say "Midtown East."
