The Grant Street Mansion located at 11th and Grant in Denver was built in 1892 in the late Victorian Era by Dennis Sheedy, one of Denver's most successful business leaders through his management of the Denver Dry Goods department store and his positions in the city's banking and mining enterprises. The Queen Anne Romanesque style structure rises three stories (plus garden level), along with a two-story carriage house. After Unbridled purchased the property in 2014 for its headquarters, the property was renovated and awarded the Jim Peiker Award in 2017 for Outstanding Historic Preservation. The property consists of 21,014 square feet of land and 21,285 square foot of building in two structures, the mansion, and the carriage house. Unbridled has improved the property with 85 individual workspaces, open offices in the carriage house, gym, individual changing rooms with showers, commercial kitchen, private meeting areas, conference rooms and well-manicured outdoor space. All major systems including the electrical, plumbing, HVAC and roof have been updated.
