One Campus Martius

One Campus Martius continues to be an important catalyst in downtown Detroit. To accommodate the owner’s staff and tenant growth, a new 16-story addition was built atop an existing three-story podium on the building’s north side. The design team envisioned it as a transparent jewel box to maximize the amount of natural day-light into each tenant floor. At the apex of the addition is the 26,000 SF event space and terrace conceptualized as an ethereal modernist, soft loft space. Curvilinear forms peel away from large masses to highlight entry, identify program and create scaled transitional moments. The material palette uses terrazzo and mixed metals throughout, and walnut panels to define each programmatic space. Faceted metal portals serve as entry points into the assembly rooms, which are wrapped in micro-perforated walnut acoustical panels. The 16-foot-tall glass along the event space provides the ultimate visual backdrop for up to 500 guests. Designed to be flexible for a variety of corporate and community events, it features state-of-the-art audio-visual and lighting packages to create additional sensory experiences.
