Superstructures Engineers + Architects is heading to the Financial District’s pyramid-topped building at 14 Wall St.

The restoration company has leased the 25th floor of the landmark building at the northwest corner of Nassau Street, which gives it 33,561 square feet.

That floor is occupied by architectural firm Skidmore, Owings & Merrill, which is moving in April to a building it designed — Silverstein Properties’ 7 World Trade Center.

Skidmore, Owings & Merrill also designed One World Trade Center.

Superstructures is currently located in Rudin Management’s 32 Sixth Avenue, aka New York Global Connectivity Center, in Tribeca, where it is nearing the end of a long sublease on part of the 13th floor from Qwest, now known as CenturyLink.

The new asking rent was much higher, and Superstructures needed more space for the growing firm, which boasts 100 architects and engineers.

The company specializes in building “envelopes” — facades and roofs — with a focus on historical structures that are mostly owned by government entities.

John Brierty of Newmark Knight Frank had represented the firm in its earlier move from Union Square to Tribeca.

After recalling the gut renovation needed to fit out its current offices, Superstructures principals — architect David May and engineer Paul Millman — asked Brierty to find them a space occupied by a similar company in the hopes of doing minimal work.

They also needed something near a transportation hub, as their employees are back and forth to hundreds of projects all over the city. And they needed extra space to hold monthly lectures to professionals in their industry.

As luck would have it, before the space was listed, Brierty heard Skidmore, Owings & Merrill was moving, and he began pursuing its offices, which had great finishes.

Designed by Trowbridge & Livingston and completed in 1912, the 1-million-square-foot 14 Wall St. was built for Bankers Trust, which used the top of the building for its logo. Financier J.P. Morgan once resided on the 31st floor, which later became a restaurant and then was converted back to offices. Now a New York City Landmark, it was the perfect place for Superstructures’ new headquarters.

Negotiations began with 14 Wall’s brokers, the CBRE team of Brad Gerla, Jonathan Cope and Paul Walker, but those talks eventually stalled.

Two months later, as Brierty was pursuing other options, the brokers were called in for a meeting with 14 Wall’s brokers as well as the building’s owner, Alexander Rovt. With everyone at the table, they quickly cut a deal.

The building’s asking rent was $55 per square foot.

“We have been growing and didn’t want to be constrained in our growth,” says Millman of Superstructures’ upcoming larger space. “Our people are passionate about what we do: the preservation of the greatest city in the world.”
