## Story

Event Company **Glasshouses** is establishing its flagship Lower Manhattan venue, **Glasshouse Downtown**, at the base of **3 World Trade Center**.

The company announced Thursday the execution of a long-term, 70,000-square-foot location at **175 Greenwich Street**. The address is within the **Westfield World Trade Center** complex, owned by Paris-based developer and operator **Unibail-Rodamco-Westfield** (URW).

“This is a defining moment for Westfield World Trade Center and the broader WTC campus,” **Geoff Mason**, executive vice president of U.S. development and operations at URW, said in a statement. “With Glasshouse bringing its world-class event space to Lower Manhattan, and the recent announcement that **American Express** will build its new global headquarters on campus, Westfield World Trade Center is evolving into an unmatched destination.”

**CBRE**’s **Anthony Dattoma**, **Chris Mansfield** and **Zachary Weil** represented URW in the negotiations, according to the landlord. It is unclear whether Glasshouses worked with an outside brokerage. A spokesperson for CBRE did not immediately respond to a request for comment.

Asking rent for the venue was not disclosed, but the build-out will require significant capital. The space is planned across two full floors of Tower 3 and is designed to accommodate nearly 1,500 guests. The venue will host corporate gatherings, conferences, nonprofit galas, productions and other large-scale social events.

“Executing this long-term lease at the World Trade Center represents a defining milestone for our company,” **Alex Holiday**, a co-founder and partner at Glasshouses, said in a statement.

Design and construction is slated for completion in 2028.

Glasshouses previously launched venues **Glasshouse Chelsea** at **545 West 25th Street**, the **Glasshouse** at **660 12th Avenue** in Hell’s Kitchen, and **GH on the Park** at **54 West 40th Street** in Midtown.
