Brooklyn’s tallest office tower tops out; see new interior renderings

By Dana Schulz

Brooklyn just keeps getting bigger. In April, the borough's tallest tower, the condo tower Brooklyn Point, topped out at 720 feet. Now, Brooklyn's tallest office tower has also reached its full 495-foot height. One Willoughby Square (or 1WSQ as it's now being called) is expected to open at the end of 2020, at which time its architect, FXCollaborative, will also become the anchor tenant. The 34-story building will contain 500,000 square feet of office space; all of the floor plans are column-free and many floors have private outdoor terraces.
