Platte Fifteen

Platte Fifteen, the first commercial project to utilize cross-laminated timber (CLT) in Denver, is a five-story office building that blends a historically inspired brick-facade to modern glass topped with sprawling views of downtown Denver and the Platte River. Located just west of the confluence of Cherry Creek and the South Platte River, it features a striking design that draws architectural inspiration from its historic and revitalized surroundings.

The building mixes patterned brick and transparency in a modern interpretation of the historic streetscape. A retail wrap along the base is tucked beneath a covered paseo, ensuring the energy of Platte Street retail turns the corner. Window patterns derived from studies of neighborhood buildings are punched into hand-selected glazed brick, subtle respectful nods to its context that enhance presence by acknowledging place. The high-performance glazing was optimized for daylight, views and thermal efficiency. In addition to the biophilic properties of wood, mass timber decreases the buildings carbon footprint while reducing material use and waste.
