The stalled construction site in Marine Park locals call “The Kimball Street Monstrosity” is a feces-filled refuge for vermin, photos obtained by this paper reveal.

The photos show dead animals, piles of excrement, and evidence of human life in the five-story, half-built structure between Avenues U and V that neighbors have long complained is rotten inside and out.

“You can’t walk by the building, the sidewalks are all broken up and nobody is maintaining it,” said Constantine Shushkovsky, president of the board of Kimball East Luxury Condominiums, which are located adjacent to the Monstrosity. “And there’s definitely been an issue with wildlife taking refuge there. There’s lots of raccoons.”

Indeed, one photo shows a cage containing the corpse of a raccoon, which had apparently blundered into the trap there and starved to death. Others depict an empty tin of cat food covered in fur, an empty six-pack of beer, and graffiti on interior walls.

Monstrosity: A stalled construction site best known as the “Kimball Street Monstrosity” has received virtually no upkeep for nearly a decade. Recently, work has occurred on an on-again, off-again basis, and the sixth floor of the overbuilt site has been removed, leaving two more illicit floors to go. Photo by Arthur De Gaeta

Construction at the condominium development halted in 2006 when the Department of Buildings slapped developers with a stop-work order for building a six-story structure in an area that was only zoned for three-stories.

The developer’s lawyers fought for years to remove the order — owners blamed their architects for the six-story snafu and said they couldn’t afford to remove the offending floors.

Meanwhile, the building languished and neighbors began complaining the forsaken site was affecting their quality of life.

The councilman at the time wasn’t buying the financial hardship excuse.

“This exactly analogues to someone who committed murder, but is asking for sympathy on the grounds that they’re an orphan,” then-Councilman Lew Fidler said.

Ow mix: Photos taken inside the building under construction on Kimball Street known as the “monstrosity” found dead animals, feces, and this empty tin of cat food covered in hair.

Locals saw a glimmer of hope after developers filed permits to demolish the condo’s sixth floor in 2013 and its fourth and fifth floors in 2014.

The Department of Buildings denied the second permit, because it was incomplete, a spokesman said. Property owners never filed a new one, and than two years later, only the sixth floor is gone.

Shushkovsky occasionally sees workers at the site, but they don’t seem to be accomplishing anything, he said.

“Six months ago, I’ve seen them once or twice, and I’ve only seen one or two guys,” he said. “One week they’ll be there for a few days, and then you won’t see them for another month, but there’s not construction going on there.”
