Calder Gardens

Calder Gardens, located along Philadelphia’s Benjamin Franklin Parkway is a one-of-a-kind underground museum and landscape designed to showcase the work of Alexander Calder.

We partnered closely with the owner and design team throughout preconstruction, providing design-assist services, constructability reviews, and budget guidance to bring the design to life. The project features a 30-foot-deep excavation, architecturally exposed concrete, complex below-grade infrastructure, and premium finishes requiring exceptional craftsmanship and coordination. Leveraging BIM/VDC, drones, and collaborative planning, our team delivered a technically complex cultural landmark defined by precision, innovation, and quality.
