707 17th Street, previously known as the MCI Building and Arco Tower, currently carries the name Jacobs Building. This high-rise is situated in Denver, Colorado. Finished in 1981, the tower stands 42 stories tall and reaches a height of . It held the title of Denver’s tallest structure until 1983 and now ranks as the seventh tallest in the city.
Initially called MCI Plaza, the building’s main tenant was MCI Inc. until the company declared bankruptcy in 2002 and was acquired by Verizon Communications in 2005. Before this acquisition, MCI occupied the upper commercial floors; however, by 2002, vacancy rates had climbed to nearly half of the building’s space. Vacancy rates improved when Carter & Burgess, an architectural and engineering firm later absorbed by Jacobs Engineering Group in 2007, leased a significant portion of office space in September 2002. This lease represented one of Denver’s largest office agreements that year. Following a merger with CH2M Hill, Jacobs relocated its headquarters and removed its signage from the building.
The hotel occupies the lower 20 floors and was originally branded as the Denver Marriott City Center. In December 2017, it was rebranded to the Hilton Denver City Center. The hotel offers 613 rooms and suites. The upper 22 floors are dedicated to office use, making this skyscraper a mixed-use property.
From an architectural perspective, 707 17th Street is notable for its distinctive "setfront" configuration where the building expands outward starting at the 21st floor. This design contrasts with more common setback styles found in other Denver skyscrapers such as 1801 California Street. The narrower base accommodates the hotel portion, while the broader upper levels contain commercial office spaces. The building’s exterior features a black glass curtain wall that exemplifies the international-style "black box" architectural approach.
