Half a Billion for South Station Tower and $405M on Park Drive: The Biggest Boston Permits of the Last Month
City permit records list five projects valued over $130 million signed off since Sept. 19, from a 432-unit Huntington Avenue tower to a theater in Allston.

You see the cranes. Here's the paperwork behind them. City of Boston permit records show the biggest-ticket approvals issued since Sept. 19.
Top of the list: 640-750 Atlantic Ave., South Station Tower, with a declared valuation of $531,845,387 on a certificate issued Sept. 22 for the base building core and shell up through the 52nd floor. That covers offices, retail, parking and multi-family condos, according to the record, and it says that certificate expires Dec. 22, 2026, pending completion.
Second: 421 Park Drive in the Fenway, $404,947,987, issued Oct. 16, for retail, offices, research and development, labs and a parking garage, basement through 13 floors.
Then 252 Huntington Ave., "Huntington Tower" in the record, at $166,732,282, covering 432 residential units across floors three through 34, issued Oct. 6. Same day, 1-9 Harbor Shore Drive in the Seaport got a temporary certificate, valued at $165,775,486, for 122 residential units plus shell space for commercial use and a future restaurant.
And over in Allston, 175 N. Harvard St. got one valued at $131,491,730, issued Oct. 7, for a theater with two performance spaces, rehearsal studios and offices.
One thing to keep straight: these are declared valuations on the permit filings, not what anybody's actually paid, and several of these are certificates closing out work that started years ago.
