BXP Secures Landmark $1.2 Billion Construction Loan for 343 Madison Avenue

Boston Properties (NYSE: BXP) has secured a major financing milestone: a $1.2 billion construction loan for its 343 Madison Avenue development in Midtown Manhattan. The loan, closed on July 28, 2026, underscores strong market backing for the high-profile project.
The facility carries a four-year initial term with an additional one-year extension option, and features a competitive interest rate of Term SOFR plus 2.50%, reducible to Term SOFR plus 2.25% upon achieving certain leasing and construction benchmarks.

This financing move advances BXP’s plans for the 46‑story, approximately 930,000‑square‑foot premier workplace tower. The building is positioned to be one of the few newly delivered office developments in Midtown Manhattan in the coming years. Leasing momentum is evident: approximately 50% of the tower is already pre‑leased, with ongoing negotiations for further commitments.

This development financing aligns with broader positive trends at BXP. In the second quarter of 2026, the company reported a 3.1% rise in revenue to $895.7 million and FFO of $1.78 per diluted share—beating the midpoint of guidance. Occupancy also rose 100 basis points to 88.4%, with leasing activity notably strong in its CBD portfolio.

Why the Financing Matters

The secured loan enhances BXP’s financial flexibility and strengthens its balance-sheet positioning ahead of project delivery, which is expected in late 2029. Situated with direct access to Grand Central’s Madison Concourse, 343 Madison Avenue is poised to capitalize on an undersupplied market for new prime office space in a key gateway location.

By financing the project under attractive terms, BXP demonstrates investor confidence in its development platform and strategic direction. The pre‑leasing progress—about 50% committed—and active lease discussions suggest strong demand for modern workplace space in Manhattan.

Strategic Context and Forward Look

This financing follows BXP’s broader strategic theme of focusing on premier workplaces in core gateway markets. In Q2, BXP executed ~1.8 million square feet of leasing, including a major agreement with Boston Dynamics at Reservoir Place, and fully placed the 290 Binney Street life sciences building into service.

Looking ahead, the secured construction financing positions BXP to deliver a signature development in a tight office tower supply environment. Investors and analysts will closely monitor leasing progress, construction timeline adherence, and how the project impacts portfolio metrics and long-term value creation.

With the secured loan now in place and about half of the space pre‑leased, BXP’s 343 Madison Avenue development stands as both a strategic anchor for future growth and a bellwether for confidence in high-quality office assets in major urban markets.
