Architecture That Makes People Stay
Vaulted atriums. Cantilevered mezzanines. Light wells that earn the density variance.

across all Atrium-designed retail environments
Measured over 24 months post-opening. Longer dwell drives F&B capture rates, higher basket sizes, and lease premiums that compound at renewal.

The Harrow
Chicago, IL
A 1.2M sq ft mixed-use repositioning of a 1988 enclosed mall. Atrium introduced a 68-foot daylit atrium spine, brass-detailed mezzanine bridges, and a ground-plane terrazzo program anchoring four experiential tenant clusters.

Four Phases. One Continuous Thread.
We begin with a forensic reading of the site: pedestrian desire lines, solar access, adjacent anchor pulls, and the acoustic character of the space. We don't sketch until we've listened.
Deliverables
"The Harrow opened at 96% occupancy. Twelve months later, our average tenant is up 38% year-over-year. Atrium didn't just design a building — they engineered a commercial outcome. I use their dwell-time model in every new acquisition underwrite now."
