Wilshire Grand Center

Wilshire Grand Center is a 1,100-foot (335.3 m) skyscraper in the Financial District of Downtown Los Angeles, California, occupying the entire city block between Wilshire Blvd. and 7th, Figueroa, and Francisco streets. It is the tallest building in Los Angeles; in California; west of the Mississippi River; outside of New York City, Chicago, and Philadelphia; and the 14th tallest in the United States. Its height surpasses the U.S. Bank Tower by 82 ft (25 m). The building is part of a mixed-use hotel, retail, observation decks, shopping mall, and office complex, expected to revitalize downtown Los Angeles and the area surrounding the building. The development of the complex is estimated to cost $1.2 billion. The plans include 67,000 square feet (6,225 m2) of retail, 677,000 square feet (62,895 m2) of Class A office space and 900 hotel rooms. InterContinental is the tower's hotel component, comprising 900 rooms and suites.

Originally envisioned as two towers, the taller of which would have been 1,250 feet (380 m) tall, the complex is now a single 1,100-foot (335 m), 73-story tower consisting of a mixed-use 889-room hotel, retail, observation deck and office space. The Los Angeles–based architectural firm, A.C. Martin Partners, oversaw the project and prepared the current design. They took over from Thomas Properties, which managed the early proposals, but which was replaced when the owners became dissatisfied with their approach. A distinctive feature of the building is its sail-shaped crown which is illuminated with LED lighting at night. The tower will spearhead part of a new planned light and sign district that will extend along the Figueroa Corridor down to L.A. Live. According to recent renderings, it is unclear however to what extent LED lighting and advertising will be applied. Lead designer David C. Martin said that the spire and the entire exterior skin of the tower will be filled with programmable LED lighting. The spire weighs 200,000 pounds (91,000 kg) and adds 294 feet (90 m) in height to the building.

The skyscraper is a distinctive part of the Los Angeles skyline, as it is the first building over 75 feet tall built since 1974 to not feature a "flat roof" design, an integral part of buildings in Los Angeles today. The pattern of buildings in Los Angeles to feature these "flat roofs" was the result of a 1974 fire ordinance which required all tall buildings in the city to include rooftop helipads in response to the devastating 1974 Joelma Fire in São Paulo, Brazil, in which helicopters could not be used to effect rescues from the rooftop of the building because of the lack of a landing spot, and could otherwise have prevented many deaths. The Wilshire Grand was granted an exception by the Los Angeles City Fire Department however, as the building will include advances in fire safety and building technology (such as a reinforced concrete central core) which would exceed the city's current fire code.

The elevators in Wilshire Grand Center are supplied by Otis Elevator Company. The four double-deck express cars servicing the hotel's main lobby on the 70th floor travel at 1600 feet per minute. More details
