A wealthy New Jersey couple who purchased a $2 million luxury condominium in Weehawken, New Jersey, claim they discovered a hazardous nightmare between the walls.

In a lawsuit obtained by Page Six and filed by Shiloh Holdings against Lennar Sales Corporation, the couple — who wish to remain anonymous — claim that when they moved into the apartment at 1200 Avenue at Port Imperial in March, they found “bottles filled with urine, containers containing remnants of partially eaten food, construction debris and other garbage” in the walls of the unit’s bathroom.

Further investigation also revealed urine-soaked insulation in the master bedroom.

As part of the Avenue Collection, the pricey two- and three-bedroom pads at the posh address range from $1,399,000 to $3,750,000 and feature “gourmet kitchens, spa-like bathrooms, spacious balconies” and some with “direct views of New York City.”

But after the grotesque discovery, the homeowners are suing Lennar for fraud, breach of warranty and are seeking punitive and compensatory damages as well as court costs. The suit also alleges the couple was led to believe the unit featured “triple-pane, hurricane proof windows,” soundproof floors and fire blocking areas.

The pee-filled receptacles were discovered by a contractor, Derrick S., who was hired to do renovations before the couple moved in.

“I notified the client I was working for … There was also food that was left in the walls. Containers [of] Chinese food with food still in it. Wrappers from cupcakes and all different stuff. The urine, [the] feces. To my knowledge that’s all very bad for your health. There were a lot of things I saw that [weren’t] up to code,” he told us.

“I’ve never ever really seen anything like this before,” he added. “There were urine bottles falling out of the ceiling. As we moved some of the insulation there were bottles of urine in it that fell out. It’s such poor quality for these people buying units spending all this money.”

The lawsuit states that while Lennar was “embarrassed” by the situation, the company only offered to open up the bottom parts of the walls for inspection, instead of all walls and ceilings.

Since the discovery, the home remains unoccupied, despite racking up maintenance fees, property taxes and mortgage charges. The couple offered to sell the home back to Lennar at the original purchase price, but it was rejected.

While Lennar did not return a request for comment on the lawsuit, Shiloh Holdings’ crisis manager Wendy Feldman had plenty to say.

“Lennar is a Fortune 500 Company. They have thousands of employees and a long history in development,” Feldman said in a statement. “I shudder to think about the rest of the work they have built. I am hopeful that everybody will do the right thing and that this never happens to another victim. My clients are not the only victims. They are the people brave enough to put their money where their mouth is and that will help anybody else who has been harmed also. As we see, it just takes one, but there are power in numbers.”

The lawyer for the couple, Phil Chronakis of Budd Larner, P.C., said, “Lennar seems to think it can get away with business as usual — by advertising luxury — while selling garbage — in Hudson County. Wrong. I’m going to have a Hudson County jury look at what Lennar did — those jurors will be outraged as should all of us.”
