Excluding ostentation, Denver's best-known Neoclassical residence has a monumental semicircular portico supported by four two-story fluted Corinthian columns. Built for James B. Grant, a smelter owner and Colorado governor, the peachy brick house employs lavish terracotta trim in window surrounds, balustrades, cornices, corner pilasters, and frieze. This early use of terracotta as a substitute for decorative stonework set an example widely copied. Interiors are on a grand scale, featuring exotic woods, plaster trim, and a sunroom addition. Second owner Albert E. Humphreys, an oil tycoon who later become embroiled in the Teapot Dome scandal, added a two-story, ten-car garage, complete with gas pump, for his fleet of Rolls-Royces. His son, Ira, donated the house in 1976 to the Colorado Historical Society, which uses it as a house museum and a party house.
