Erected in 1892, the Equitable Building features a massive groin-vaulted lobby with elaborate mosaic tiles, exotic marble walls and floors, Tiffany-stained-glass windows, a grand staircase finished in gleaming bronze, and exquisite brass finishes. St. Charles developed this 205,000-square-foot building in 2000 and sold 65% of the office condominium units within a year.  Total project costs were $34 million and helped to rejuvenate one of Colorado’s largest historic structures.
