  1. Grand 29,190 sq ft historic building, originally constructed in 1925 with striking Art-Deco styling. Rock Island Official Website+2LoopNet+2

  2. Former home of the locally-renowned newspaper, the Rock Island Argus, giving the building both story and status. Rock Island Official Website+1

Investment highlights

Why This Property Stands Out

  • Historic character with modern potential: From the stone-faced façade and decorative urn motif above the entrance to the expansive floor plates (~9,190 sq ft per typical floor) it radiates legacy—while the interior presents a canvas for contemporary innovation.

  • Central downtown anchor in a designated historic district: The Argus Building contributes to the legacy and vitality of Rock Island’s downtown—making redevelopment and tenant attraction compelling.

  • Competitive lease pricing with flexibility: Current listing indicates asking lease rates in the range of $15-$18/sf offering a cost-effective footprint for tenants seeking above-average infrastructure and downtown location.

Ideal Use Cases

  • Professional services or legal firms seeking headquarters in a landmark building

  • Creative/multimedia studios or technology co-working spaces that value unique architecture

  • Mixed-use redevelopment into loft offices, premium suites, or campus-style configuration

  • Non-profits or associations looking for a distinguished address with walk-to amenities

Location & Access

Located in the 61201 zip code, the building is within the dynamic downtown Rock Island area—with proximity to dining, cultural institutions, government operations, transit corridors, and the Mississippi Riverfront.
