Cortex Breaks Ground on First New-Construction Residential Project

“The addition of Iris represents an important step in building a truly mixed-use innovation district,” said Sam Fiorello, President & CEO, Cortex. “As Cortex continues to grow as a center for research, technology, and entrepreneurship, expanding high-quality housing options within walking distance of jobs and transit helps create the kind of vibrant, connected community that attracts and retains top talent.” 

The project represents a successful public-private partnership, bringing together key stakeholders committed to the continued growth of Cortex and the City of St. Louis. Partners include the City of St. Louis, St. Louis Development Corporation (SLDC), Alderman Michael Browning, the Arch to Park Equity Fund, Arcturis, and Cortex. Holland Construction Services will serve as general contractor. 

“Iris is another example of the positive momentum happening in the City of St. Louis and across the 9th Ward,” said Michael Browning, City of St. Louis Alderman. “Projects like this bring new housing, activate our streets, and reconnect areas of our city, strengthening our economic engine, where Cortex is such an important driver for the City of St. Louis. I’m proud to support development that invests in our neighborhoods and creates opportunity for residents. Iris’s proximity to transit and future greenway connections makes this an especially accessible and livable addition to the neighborhood.” 

“Advancing development in Cortex has been a goal of the Arch to Park Equity Fund since it was established,” said Dustin Allison, CEO, Arch to Park Equity Fund. “The Fund’s significant investment in Iris reflects our strong belief in this project and that Cortex is positioned for even more growth in the years ahead." 

Iris represents Phase 1 of development on the site. Phase 2 is expected to include Class A office space and structured parking, further expanding the Cortex District's capacity to attract and retain top talent and innovative companies. 

Keeley expects to complete Iris and begin leasing in Q1, 2028.  The company also controls over two acres surrounding the project for future phased development, including tech office and retail uses.
