Even before completion, the press touted the Cass Mansion as “one of the most attractive of Denver’s attractive homes…” and “one of the handsomest in the vicinity…” One newspaper announced that the price would reach the staggering sum of $13,000, and the reporter justified that by commenting that the residence was to be “first class,” “modern in every particular,” with “no expense spared.”

The articles did not exaggerate; the home was masterfully conceived from its design to its final details by two of the foremost architects in Denver’s history: Willis A. Marean and Albert Julius Stead Norton, whose work also includes The Brown Palace Hotel, the Colorado Governor’s (Boettcher) Mansion, and the Cheesman Park Pavilion. These prominent architects combined Dutch Revival style with contemporary Victorian features to create the Cass Mansion.

Today, the Cass Mansion still displays the details that placed it among the finest residences of its time. A 19th century Scottish stained glass window, brought from Glasgow, decorates the foyer, arched cabinets and moldings of golden oak provide a warm atmosphere, the main staircase has custom-designed oak railings and banisters, and seven beautiful fireplaces still heat the spacious rooms during the winter.
