Carter’s Review

"This former industrial building at 30 Main Street in Dumbo (Down Under the Manhattan Bridge Overpass) in Brooklyn was converted to residential condominiums in 2000 by Two Trees Management, which is headed by David Walentas.

The building, which is also known as 74-86 Water Street, is known as the Sweeney Building because it was erected by the W. H. Sweeney Manufacturing Company in 1908 at the northwest corner at Howard Alley."
