Mixed-Use

Today’s mixed-use projects hold tremendous potential in the realm of placemaking and design. In this era of “18/7” do-everything environments where people live, work, shop, eat, and play, we carefully explore each project through the lenses of urban design, architecture, and interior design. We see the challenges of urban sites as chances for creative invention. Drawing on our affinity for interdisciplinary cooperation and clever design solutions, we create lively, beautiful, multi-functional developments that increase the connectivity, visibility, and value of dense urban places.
