The Offering

Newmark, in conjunction with RI Marketplace, has been retained by the court appointed Receiver to offer for sale Unit 1 of 1831 Chestnut Condominium (the “Property”), a 336,392 SF office condo, along with an 81.23% percentage ownership in the Common Elements. The Property previously hosted Anthem's primary Missouri data center operations with institutional-grade data infrastructure. The Common Elements include the adjacent surface parking lot, an attached parking structure, and a freestanding parking garage across 18th Street. Parking at the project totals approximately 1129 spaces, of which 983 are allocated to Unit 1. The Property is fully vacant as of 1/1/2026 and sits on a 4.24-acre site.

The Offering includes Unit 1, consisting of the lower level, floors 1 through 5 and floors 8-9 (Unit 2, which includes floors 6 & 7, is separately owned and not included in the offering). For 32 years the Property served as the Missouri regional home of Anthem Blue Cross and Blue Shield, one of the nation’s largest health insurers. Vacant as of January 1, 2026, the Property features continuously maintained building systems, extensive parking inventory, and large, flexible floor plates. Also included in the offering is an 81.23% interest in the Common Elements, which include +/- 1,129 parking spaces across three components: an attached garage with 191 spaces, a western surface lot with 66 spaces, and a detached standalone garage across 18th Street with 872 spaces.

The opportunity provides investors with flexibility to execute on a broad range of repositioning strategies, from office lease-up, data center re-use or expansion, residential conversion, hospitality, or educational uses, in one of Downtown St. Louis’s most activated and rapidly evolving entertainment corridors. Situated immediately adjacent to Energizer Park (St. Louis SC – MLS), Enterprise Center (St. Louis Blues – NHL), and the recently redeveloped Union Station, the Property offers an exceptional urban footprint at an extraordinary basis.

The sale of the Property is subject to the Receivership order and court approval.
