This nine-story residential building will rise on a slender corner lot at the intersection of St. Nicholas Avenue, across the street from St. Nicholas Park in West Harlem. Designed and developed by AQC Architects and Elod Studio, this project sits directly at the subway entrance for the A, B, C, and D trains running below the street in front of it.  Madsen worked together with Langan, the geotechnical and support of excavation engineer to obtain approval from the NYC Metropolitan Transit Authority. The structural system consists of composite concrete on metal deck slabs supported by a steel structure. 

The building is supported by a reinforced concrete mat with additional rock anchors to account for uplift; one area of mat would step to create a “shelf” to avoid underpinning one of the adjacent structures. Two subway station entrances are immediately adjacent to both sides of the corner lot.
