To clarify, both towers are being built on the same parking lot dotted in red here. Plaza 8 is on the south side of the parking lot, Plaza 9 on the north side.
This is an older render, but Harborside 9 is the smaller one on the right
EDIT: Though looking at it more closely, it appears that at the time Harborside 9 was going to be two towers (and the whole Harborside 8-9 a total of 3 towers).
This has now been acquired by GN Management, aiming to begin construction in 2027:
The sale follows broader onsite progress – including Panepinto Properties’ acquisition of development rights from Veris Residential Inc., for $75 million, and the advancement of Harborside’s Master Plan, which calls for more than 1,200 new residential units across dual sites encompassing 4.2 total acres (both Harborside 8 and 9).
While Panepinto continues to lead development of Harborside 8 (a future 65-story mixed-use tower) – where construction is now underway – the transfer of development rights and ownership for Harborside 9 ensures both phases can move forward on essentially similar timeframes.
