Design and construction

801 Grand, also known as the Principal Building, is a 45 story skyscraper in Des Moines, Iowa, United States. It is named after its street address along Grand Avenue in the downtown area of the city between 8th and 9th Streets, with High Street the northern border. Completed in 1991 and standing 630 feet (190 m), it is the tallest building in the state of Iowa. The building is primarily office space, largely occupied by its owner, Principal Financial Group. The lower three floors contain retail and restaurant space, including the 801 Chophouse, and provide a connection to Des Moines' skywalk system. Other tenants include the law firms of McKee, Voorhees, & Sease; Bradshaw, Fowler, Proctor & Fairgrave; and Faegre Baker Daniels.

801 Grand's roof is covered with copper sheeting that was designed to form a green coating of verdigris over time, much like the Statue of Liberty. However, unlike New York City, the air salt content in Des Moines was so low that the desired oxidation process failed. The copper turned a dark brown instead. Discussions on possible removal of the top layer of copper to allow crews to restart the oxidation process to create verdigris resulted in the decision to leave the roof as it is.[citation needed]
