The Volume Coming Online
Demolition started at 350 Park Avenue in Midtown East in July 2026. The site will carry 1.8 million square feet of Class A office space across 64 stories at 1,414 feet. Capacity is 6,000 employees. Foster + Partners designed the tower. Vornado Realty Trust, Rudin and Ken Griffin are the development partners. Citadel and Citadel Securities anchor the building with at least 850,000 square feet.
Day-use inventory sells hours inside a hotel's day. The office pipeline sets how many people will want those hours. The 53,000-square-foot site spans the block front between East 51st and 52nd Streets. Three buildings come down: the 30-story midcentury tower at 350 Park Avenue, a 23-story building at 40 East 52nd Street, and a five-story building at 39 East 51st Street.
The Delivery Timeline
Demolition completion is anticipated around March 2027, per site signage reported by Our Town. Waldorf Demolition is the general contractor named on that signage.
Project completion is targeted for 2032. Hotel Pulse labels that date a target. The developers have published no steel start, no topping-out date and no tenant occupancy date.
Manhattan's office market has absorbed part of the volume. Citadel and Citadel Securities committed at least 850,000 square feet of the 1.8 million. Commercial Observer reported on 2 January 2025 that Citadel signed for 504,000 square feet at Brookfield's 660 Fifth Avenue while it waits for the new tower. Citadel held space at 350 Park Avenue and moves into the replacement building on completion.
The District Hotel Supply Picture
PwC's Manhattan Lodging Index for January to June 2026 counts four new Manhattan hotels for the first half, adding 1,328 rooms to the market. IHG Hotels & Resorts opened three of the four.
The Midtown East addition is the Kimpton Ashbel New York. IHG opened it on April 30, 2026 at 70 Park Avenue, with 205 guestrooms in a Beaux-Arts landmark built in 1928 as the Doral Park Avenue Hotel. The address sits steps from Grand Central Terminal and Bryant Park.
PwC reports Manhattan supply growth running behind demand growth. It reads that gap as support for operator pricing power. The same report names stricter zoning as a risk that carries delays and cancellations for the development pipeline.
The Demand Side
Manhattan hotel occupancy averaged 80.7 percent in the first half of 2026, down 1.7 percent. ADR rose 6.3 percent. RevPAR rose 4.5 percent. Rate carried the growth.
Midtown East occupancy fell 3.6 percent in the first half. PwC describes the district's result as a reversal from its 2025 position. Midtown West RevPAR gained 3.9 percent. Manhattan luxury hotels gained 7.9 percent in RevPAR, and full-service hotels gained 5.3 percent.
New York metro air traffic fell 2.1 percent year over year in the first half, and international arrivals fell 4.2 percent. PwC ties midweek hotel demand to corporate travel and to the office recovery.
Manhattan office leasing reached 17.7 million square feet in the first half of 2026, up 12.6 percent year over year. Office vacancy fell to its lowest level since the third quarter of 2021. PwC names financial services, legal and artificial intelligence leasing as the drivers.
What the Projections Show
The pipeline delivers 1.8 million square feet of office in 2032, six years from the demolition start. PwC projects that the office recovery will lift corporate travel and midweek hotel demand. That projection rests on return-to-office mandates and on expanding corporate footprints in the sectors PwC names.
Day-use inventory comes from the district's existing hotels. The window between the demolition start and the 2032 delivery carries two populations: construction crews through March 2027, then office tenants from 2032. No published forecast reviewed for this article sets a day-use or room-night figure for Midtown East against the 350 Park Avenue delivery. Hotel Pulse asks the district's operators for their own day-use booking data across the window.
Two dates drive planning across the next six years. Demolition runs to about March 2027. Completion is targeted for 2032. Both stand as targets. Hotel Pulse will report each published revision as the developers release it.
