BXP Begins Vertical Construction of 343 Madison Avenue Trophy Tower

What sets this project apart is its strong pre-leasing momentum: BXP has signed a letter of intent with a prominent financial firm to serve as the anchor tenant. Though the tenant’s identity remains undisclosed, the early commitment is a significant endorsement for the project and a positive sign for Manhattan’s premium office sector.

The 343 Madison tower is expected to be a state-of-the-art asset offering cutting-edge amenities and transit connectivity — key features for companies seeking modern, centralized headquarters. With brand-new office buildings becoming increasingly scarce due to high construction costs and financing challenges, this project positions BXP as a leader in reshaping Midtown’s Class-A office landscape.

This development aligns with BXP’s broader strategy of investing in top-tier office assets in core markets. As corporate tenants continue their flight to quality, BXP’s latest move reflects confidence in long-term demand for trophy office space in New York’s most connected business district.
