Major Private Office Owners and Their Strategies

Introduction

The private (non-REIT) office ownership world is easiest to read through a single split: developers who manufacture new supply against acquirers who buy mispriced existing supply. Tishman Speyer sits on the first side, building trophy towers it expects to lease at the top of the rent stack; RXR Realty sits on the second, buying existing Manhattan towers at discounts to replacement cost because demand cratered. Both are betting on premier office space and simply entering the bet from opposite ends, and which end a platform plays from is the single most useful thing to know about it before any deal opens.

It matters for RE IB coverage because these platforms are the counterparties. When a listed office REIT runs a take-private process, sells a tower, or strikes a joint venture on a redevelopment, the bidder or partner across the table is usually one of these private owners rather than another public REIT. Hines, Brookfield Properties, and Silverstein Properties round out the set of names that recur in office deal conversations, each running a recognizably different playbook.

Tishman Speyer, founded by Robert Tishman and Jerry Speyer in 1978, owns one of the most iconic trophy office portfolios in the world. The flagship is Rockefeller Center, the multi-building Midtown Manhattan complex that remains one of the highest-value trophy office assets anywhere. The wider portfolio includes the MetLife Building at 200 Park Avenue, the Chrysler Center, and trophy assets in markets from Frankfurt to São Paulo. Across its history the firm has acquired, developed, or managed more than 116 million square feet of real estate valued at over $50 billion.

What separates Tishman Speyer from a pure asset manager is that it manufactures trophy product rather than only buying it. Through 2024 the firm ranked among the largest commercial real estate developers in the country, having delivered roughly 13 million square feet of space between 2022 and 2024 at a value near $9.7 billion, with another 10 million-plus square feet under construction. Ground-up development of this kind requires expertise, multi-year capital, and the patience to carry a building through a long lease-up before it stabilizes. That is the trade the developer camp accepts: longer time horizons and construction risk in exchange for the highest rents in the market when the building fills.

Hines is one of the largest global private real estate platforms, founded by Gerald Hines in 1957 and now run by his son Jeffrey Hines. The platform spans office, multifamily, industrial, and other property types across the US and internationally, with assets under management measured in the hundreds of billions. The office franchise is one of its anchors, with a major presence in most top US markets and a deep international footprint.

Hines does not fit cleanly into the developer-or-acquirer split, and that is the point. Its capital base blends fund-vehicle capital (separate-account and commingled fund structures raised from limited partners) with direct sponsor investment, so the firm can develop, acquire, joint-venture, or do a sale-leaseback depending on which opportunity the cycle is offering. A platform built around a single strategy has to wait for its kind of deal to appear; a multi-strategy platform like Hines can lean into whatever the market is mispricing at the moment, which is why it stayed among the more active office acquirers through the post-pandemic dislocation.

Brookfield Properties is the real estate arm of Brookfield Asset Management (the publicly traded parent), with a global portfolio of more than 340 million square feet and roughly 65 million square feet of US office across some 85 buildings. Its New York office presence centers on Brookfield Place, the Lower Manhattan complex on the Hudson, and Manhattan West, the roughly 7 million square foot Hudson Yards-adjacent development that ran about 95% leased through the dislocation, a concrete data point for the flight-to-quality thesis that newer, better-amenitized towers held tenants while older stock emptied.

The platform's defining feature is the public-company balance sheet behind it, which produced one of the cleaner NAV-discount trades in recent real estate history. Brookfield Properties was historically organized around Brookfield Property Partners (BPY), a publicly traded vehicle whose units traded at a meaningful discount to the underlying real estate NAV. In 2021 the parent took it private, paying $18.17 per unit for roughly $6.5 billion of consideration to public unitholders and folding the platform back inside Brookfield Asset Management.

RXR Realty, led by Scott Rechler, runs the cleanest example of the acquirer playbook: opportunistic buying of discounted Manhattan office in the post-COVID dislocation. In September 2025 the firm launched the Gemini Office Venture, a multibillion-dollar platform built specifically to take down high-quality New York office at a discount to replacement cost. Gemini's commitments topped $3.5 billion in transaction value, positioning RXR to acquire interests in more than 7.5 million square feet of premier space. Its initial portfolio shows the type: 590 Madison Avenue, bought for over $1.0 billion (the largest full-asset office acquisition in New York since 2018), the 2.2 million square foot Starrett Lehigh Building, and 1211 Avenue of the Americas.

The thesis is straightforward and the entry timing is everything. Manhattan office repriced far enough during the structural transition the office market went through after 2020 that genuinely good buildings could be acquired below replacement cost and well under pre-pandemic marks, an attractive entry for a long-duration holder willing to underwrite a multi-year recovery. The flip side is that this is a window, not a permanent strategy. Once Manhattan office prices recover, the entry-point arbitrage closes and an opportunistic buyer either becomes a stabilized owner or sells into the recovery it underwrote.

Silverstein Properties is the Larry Silverstein-led platform with 40+ million square feet across its New York-centered portfolio. The company is best known for redeveloping the World Trade Center site after September 11, 2001 (Silverstein held the long-term ground lease at the time of the attacks and was the lead developer of the rebuilt complex). Beyond the WTC site, the portfolio includes major Manhattan office assets and selected development pipeline.

Other significant private office owners include Vornado (which operates a public REIT but also holds private joint-venture investments alongside it), DivcoWest (a West Coast-focused private office and life sciences platform), Beacon Capital Partners (a Boston-based platform with portfolios across major US markets), and the Related Companies (best known for Hudson Yards but with broader office and mixed-use exposure). Each carries a different geographic and strategic tilt, and each surfaces in a different transaction context, whether as a bidder, a JV partner, or a buyer of assets the listed office REITs (BXP, SL Green, Vornado) are shedding.

Strategic-Camp Comparison

Private Office Owner

A real estate platform that owns and operates office assets through private-fund or direct-investment structures rather than through a publicly traded REIT. The category spans long-tenured family-led platforms (Tishman Speyer, Silverstein), global multi-strategy platforms (Hines, Brookfield Properties), opportunistic acquirers (RXR through the Gemini Office Venture), and sub-market specialists (DivcoWest in West Coast life sciences, Beacon Capital in regional office).

The reason to hold these names is that they are the other side of nearly every office deal a banker advises on. A REIT does not take itself private, sell a tower, or recapitalize an asset in a vacuum; a Tishman Speyer, a Hines, an RXR is usually the bidder, the JV partner, or the buyer. Knowing which camp a given platform sits in tells you, before any process opens, what it is likely to want and what it can pay: a developer is hunting sites and long-dated capital, while an opportunistic acquirer is hunting mispriced existing stock and a fast close. That read on the counterparty is what turns a list of firm names into something useful in an office coverage conversation.
