141 Willoughby takes advantage of its prominent full-block location to establish its credentials as an urban asset. Occupying a trapezoidal site greeting motorists and pedestrians as they cross the Manhattan Bridge, the 24-story office building steps down toward the East River and reinforces the street wall along Flatbush Avenue to show it’s a team player in the on-going process of creating a new, high-density civic realm for the area. A small park at the narrow tip of the property, previously the site of a three-story printing plant erected in 1919, adds to this effort with curving benches and three clusters of trees inviting pedestrians to pause and relax.
