BNY Tower Holdings is the venture that built and owns Dock 72, a 16 storey office building of about 675,000 square feet standing on a pier in the Brooklyn Navy Yard, surrounded by water on three sides and looking across the East River to Manhattan. Designed by S9 Architecture and completed in 2019, it was the first ground up Class A office building in Brooklyn in more than 15 years, and its selling point is large column free floors with 14 foot ceilings, full height glass, private terraces and roughly 40,000 square feet of shared amenity space including a wellness centre, conference and event rooms, food offerings and a half court basketball court. Rudin Management developed the tower with BXP, and WeWork took about a third of the building as anchor tenant at opening.

BNY Tower Holdings LLC (Dock 72) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Dock 72 property page (Rudin), With 222K SF WeWork Anchor, Rudin Set To Open Dock 72 Office Project (Bisnow) and BXP, Inc. Form 10-K for 2025, Exhibit 21.1 list of subsidiaries (SEC). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of BNY Tower Holdings LLC (Dock 72) where a holder stated one, and are missing where no holder did.
