Commercial Real Estate Solutions

Calamos Real Estate logo

What makes Calamos Real Estate different?
We are owners. We are tenants. We know what you expect because we expect it too.

We own, manage and lease 1.2MM square feet of commercial real estate and, as part of Calamos Property Holdings LLC, we also are tenants, leasing offices from other owners on behalf of our sister companies operating in Downtown Chicago, New York, San Francisco & Milwaukee.

We’ve been where you are: Striking the balance between consolidation of operations and efficiently managing hybrid working conditions, identifying and accessing the property amenities that help attract & keep talent with desirable locations; and along the way managing around supply chain disruption and planning for the unexpected – always with the clear expectation of top-notch accommodations and service.


Our dozen properties in Naperville and throughout  DuPage County include 400,000 square feet of Class-A Office at CityGate Centre, plus properties with uses spanning from office to education, retail to aviation, healthcare to hospitality, and restaurant to parking structures. We also have more than 25 acres ready for development in Naperville.
