A new generation of Manhattan towers is being built on one idea: the office has to be a place people want to be. 270 Park Avenue, 350 Park Avenue, 343 Madison Avenue and Penn 2 each raise the bar on design, sustainability and amenities, so that the commute is worth making.
This is the ground-up end of the market. For the other route to modern space, older buildings bought and repositioned, see how value-add owners turn older buildings into Class A.
270 Park Avenue
JPMorgan Chase's new global headquarters, designed by Foster + Partners, is set for completion in late 2025. The 1,388-foot, 70-story supertall brings 2.5 million square feet and is billed as New York's first zero-carbon, all-electric office building. It is powered entirely by hydroelectricity and built with 97% recycled materials.
The interior is organized around light and space. Trading floors have 15.5-foot ceilings, and a triple-height communal space called the Exchange sits at the center, in line with Foster + Partners' wellness-focused approach to the workplace.
What 270 Park builds in
- A food hall with nearly 20 curated options
- Wellness hubs with yoga and cycling studios
- Healthcare and physical therapy services
- Meditation and prayer rooms
- Terraces that bring light into high-ceilinged event and collaboration spaces
- An 80-foot lobby, an LED-lit diagrid facade and expanded plazas along Park Avenue
350 Park Avenue
Citadel's 350 Park Avenue, also by Foster + Partners, is 270 Park's closest rival: a 62-story, 1.5 million square foot supertall between the Seagram Building and the Lever House. It is the clearest symbol of the Midtown rezoning, which now allows Park Avenue towers of a height once thought impossible.
343 Madison Avenue
BXP's 343 Madison Avenue is a 46-story, roughly 1 million square foot tower designed by KPF. It is fully electric and targets LEED Platinum, WELL Core, WiredScore Platinum and Energy Star certifications. Tiered setbacks create landscaped terraces. Inside are double-height lounges, top-floor indoor-outdoor conference space, a lobby cafe, and end-of-trip facilities with bike storage, showers and cabanas. The building connects directly to Grand Central.
Demolition wrapped in 2023 and construction permits are in place. The schedule depends on signing an anchor tenant by Q3–Q4 2025, with delivery projected between 2026 and 2029.
Penn 2
Penn 2 is already finished. It doesn't change the skyline, but it re-engineers the office around it. Following the Penn 1 renovation, the 31-story building offers 1.8 million square feet of trophy-class space, connected directly to Penn Station and Madison Square Garden, with restaurants and amenities across both buildings.
It was designed by MdeAS Architects with Vornado Realty Trust, and Foster + Partners led the broader Penn District masterplan (see the Penn Station renovation). A district that was once dull to visit now sits alongside Hudson Yards as a destination.
What comes next
Planned developments including 15 Penn Plaza, 520 Fifth Avenue and 70 Hudson Yards will extend the pipeline. The direction is already clear: new towers now compete on experience as much as on floor area, with all-electric systems, food and wellness built in, and a direct line to transit.
Tenants should not assume this product is only for the largest companies. Furnished, pre-built suites in a building like Penn 2 put new trophy space within reach of a smaller team that needs to move quickly, and they belong in the comparison alongside conventional options.
