BXP (NYSE:BXP), the largest publicly traded developer, owner, and manager of premier workplaces in the United States, today announced that McDermott Will & Schulte has signed a lease for approximately 150,000 square feet at 343 Madison Avenue in New York City. The firm will occupy floors 31 through 37 of the 930,000 square foot premier workplace, which is currently under construction and will provide direct access to Grand Central Terminal's Madison Concourse between 44th and 45th Streets.

"McDermott Will & Schulte's commitment to 343 Madison Avenue underscores the building's strong leasing momentum and the sustained flight to quality shaping the market," said Hilary Spann, Executive Vice President, New York Region, BXP. "Midtown Manhattan and the Grand Central corridor have continued to outperform as demand concentrates around best-in-class assets with exceptional transit access. As companies prioritize workplaces that drive talent attraction and retention, 343 Madison offers a rare combination of connectivity, flexibility, and premier amenities in the heart of Manhattan."

McDermott's footprint will feature more than 330 offices, spanning seven floors with versatile conference facilities, and a large outdoor terrace, creating a high-performance environment for both colleagues and clients. The lease is a component of McDermott's campus strategy, linking their occupancy in an adjacent property through Grand Central Terminal and providing a client-hub at the center of the global private capital ecosystem. The firm expects to begin occupying the new space in October 2029.

"McDermott's expansion to 343 Madison comes amid rapid growth in our New York presence, where we've increased our footprint tenfold over the past decade and recently rose into the top 10 largest firms in the city," said Ira Coleman, chairman of McDermott Will & Schulte. "We are redefining what a modern law firm can be by combining innovation, scale and client focus in this vibrant, technology-enabled space."

McDermott Will & Schulte will join global investment and insurance organization Starr, who signed a 275,000 square foot lease at 343 Madison in December 2025. Starr recently exercised an expansion option for an additional two floors, comprising approximately 46,000 square feet, bringing their total occupancy to 320,000 square feet over fourteen floors. Together with additional leasing commitments, these transactions bring 343 Madison to 56% pre-leased.

Designed by Kohn Pedersen Fox, the 46-story tower will offer a hospitality-forward amenity program and market leading sustainability features. A dramatic double-height, client-exclusive club on the top floors will include spaces to dine, connect, and collaborate indoors and out, with striking terraces and expansive views overlooking Midtown. A robust food and beverage program including a lobby café and bicycle storage with cabanas and showers round out the amenity program. Specialty floors, including private terraces and elevated ceiling heights, allow clients to design a multi-functional workplace that accommodates a variety of work styles and space needs.

Sustainability features include a fully electric design with zero on-site combustion and a high-efficiency direct outside air system. Target certifications include LEED Platinum, Well Core, Energy Star 85+, Fitwel, and WiredScore Platinum. BXP expects to deliver 343 Madison in late 2029.
