An empty lot on White Street in Lower Manhattan may look very different seven years from now.

An exclusive first look at the potential design of a new jail in Manhattan showed it gleaming with floor-to-ceiling windows on the first floor.

NY1 obtained a conceptual walkthrough, done as part of the contract process — a contract now in its final stages of approval with Los Angeles-based firm Tutor Perini and O&G Industries.

The contract’s price tag is more than $3.7 billion, with an expected completion date of August 2032.

“There is still areas where we can improve, where we can do things, faster, smarter, hopefully for less money,” Zachary Katznelson, the executive director of the Independent Rikers Commission, said.

Katznelson leads the city’s Rikers Commission, which is examining how the city can move forward with closing the troubled jail complex.

Rikers is supposed to close in 2027, but a review of the new Manhattan jail contract by NY1 shows the facility will be nowhere close to completion by then.

The other jails in Brooklyn, Queens, and the Bronx have completion dates well past 2027 as well.

“By the city’s own estimate, it would cost up to 15% more to rebuild jails on Rikers than to build them in the communities,” Katznelson said. “So we’re really excited that plans are moving forward in the boroughs, even though they’re costing more than we would hope and certainly taking longer than we would hope.”

Recently, Mayor Eric Adams suggested building an entirely new facility — a jail for the severely mentally ill. But the seriousness of that proposal is unclear, including whether the mayor aims to replace one of the new jails currently under contract.

The Manhattan jail building will be 16 stories, with community and retail space on the lower floors. The secure jail facility will be on floors five through 16, according to the contract.

The contract states the building will avoid an institutional look, and the jail will ultimately be a humane, dignified place for healing.

In response to this story, a spokesperson for City Hall sent NY1 the following statement: “While the Adams administration will always follow the law, it has become painfully clear that the plan approved under the last administration leaves open serious questions about the city’s ability to keep New Yorkers safe.”
