The Chicago studio of architecture firm Lamar Johnson Collaborative (LJC) is on the 15th floor of landmark 35 East Wacker, formerly known as the Jeweler’s Building—a nod to the jewelry trade offices and showrooms originally located within. In 2019, LJC relocated from Chicago’s West Loop to this new larger space along the river.

Envisioned as a hospitality-focused studio, the design blurs the lines between amenity and workplace. On the north side of the office, a welcoming reception area brings everyone together for formal meetings and impromptu gatherings. Distinct “neighborhoods” comprise the east and west sides, providing collaborative workspaces and breakout areas that support the studio environment. Along the perimeter hangs large, removable presentation boards, enabling flexibility and encouraging alternative standing collaboration space. The south side is focused on internal teams.
