320 W 135th street
New York, NY
This nine-story residential building is located on a slender corner lot at the intersection of St. Nicholas Avenue, across the street from St. Nicholas Park in West Harlem alongside the urban void created by Dorrance Brooks Square. The new construction is a nine stories building with two retail spaces at ground floor, seventeen residential units above and a rooftop terrace overlooking St. Nicholas Park. A brick façade wraps the volume maintaining the street wall of the contiguous buildings.
Designed and developed by Elod Studio and Artifact, 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 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 steel structure 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.
This was a full service project - Madsen also provided structural steel shop drawings and connection design for this project.
