Half a building leased is what it now takes to get a Manhattan office tower financed.
BXP closed a $1.2 billion construction loan on 343 Madison Avenue on July 28, one of the largest single-asset office construction financings in New York since rates turned. Wells Fargo led the syndicate, joined by Bank of America, BNY Mellon and JPMorgan Chase. Total project cost is around $2 billion.
The terms tell you where the risk sits
The loan prices at SOFR plus 250 basis points, dropping to plus 225 once the borrower hits defined leasing and construction milestones. Four-year initial term, one-year extension option. BXP said it was close to a deal with an equity partner at closing.
Read the step-down as a scoreboard. The lenders aren’t worried about whether the building gets built; they’re worried about whether the back half leases. Twenty-five basis points on $1.2 billion is $3 million a year, which is the price the syndicate put on that specific uncertainty.
Why Grand Central keeps clearing the market
The tower runs 46 floors and about 930,000 square feet, designed by Kohn Pedersen Fox, with delivery expected in 2029. Its defining feature is the connection: direct access to Grand Central Terminal’s Madison Concourse, so tenants walk from Metro-North, the LIRR and four subway lines into the lobby without stepping outside.
East Midtown has produced a short run of towers, One Vanderbilt and 175 Park among them, that leased at record rents on essentially that one attribute. 343 Madison is the same trade at smaller scale and lower basis. Roughly 50% pre-leased at loan closing suggests the tenants agree.
What it says about the office market
Speculative Manhattan office construction has been effectively unfinanceable since 2023. What reopened isn’t the office market broadly, it’s a narrow lane for new, transit-connected, heavily pre-leased product from a sponsor with a balance sheet. Everything else is still waiting.
No general contractor has been named publicly. Full details are in the 343 Madison Avenue project listing, and for a look at how differently the residential side of this cycle is being capitalized, see 410 North Elizabeth in Chicago.
