## Background

The history of skyscrapers in Denver began with the completion of the Equitable Building in 1892; this building, rising 143 feet (44 m) and nine floors, was the first high-rise in Denver. The title of the city's "first skyscraper" is usually given to the Daniels & Fisher Tower, which rises 325 feet (99 m) and was completed in 1910. The city went through a large building boom that lasted from the early 1970s to the mid-1980s. During this time, 21 of the city's 27 tallest buildings were constructed, including Republic Plaza, 1801 California Street, and the Wells Fargo Center. The city is the site of eight skyscrapers over 492 feet (150 m) in height, including two which rank among the tallest in the United States. Overall, the skyline of Denver is ranked (based upon existing and under construction buildings over 492 feet (150 m) tall) second in the Mountain States (after Las Vegas) and seventeenth in the United States.
The tallest building recently completed in Denver is the Four Seasons Hotel and Tower, which rises 45 stories and 641 feet (195 m). It now stands as the fourth-tallest building in Denver as well as the city's tallest residential tower. The 1144 Fifteenth office tower rises just over 600 feet at over 40 stories making it the fifth-tallest building in Denver upon completion early 2018. Denver is currently experiencing a mid-high rise residential building boom with several large projects under construction throughout the city and more than 20 new projects breaking ground downtown Denver, golden triangle and RINO in 2023.
