The Knickerbocker, a 49-unit condo building, is on the docket for 320 Knickerbocker Avenue in Bushwick. It’s an adaptive reuse project that will “transform some of the neighborhood’s finest historic housing stock into modern, loft-like apartments while adding a new top floor containing dramatic penthouse units,” according to their Web site. Some 40% of units have terraces or patios, and there’s a gym, “virtual doorman,” storage and roof access. It’ll be LEED-certified. Here’s the review from our tipster: “Knickerbocker Condominiums is located one block from Maria Hernandez Park and two blocks from both the L and M trains. They’re incorporating most of the block along Knickerbocker along with an old 4 floor-walk-up building around the corner, visible in the photo on the far right (check out Curbed for the rendering).The building was a large grocery store on the first floor for years. This establishment closed two or three years ago.” No word on prices, but seems pretty high-end. Is Bushwick — “up and coming,” per the developers — ready?
