First Interstate Center is a signature commercial office building located in the Transwestern Plaza, a complex consisting of four office towers with a total of 20 floors in the Downtown Core of Billings, Montana.
 It is the tallest building in the northern Rockies, and the tallest in the state of Montana.
 It was built in 1985 and rises to 272 feet (83 meters).
 It is used primarily for office space.
This is the main financial, business, cultural and medical area of Billings and the surrounding areas and is home to several high-rise buildings including Montana's tallest high-rise, the First Interstate Center.
The Town House is a historic apartment building located at 718 S. 7th Street in Springfield, Illinois.
 The high-rise building is composed of an 11-story section and a 13-story section joined by a 14-story connector.
 Built in 1958, the International Style building was designed by Chicago architectural firm Shaw, Metz and Dolio.
 Springfield's Franklin Life Insurance Company underwrote the building; while it was originally intended to serve as employee housing, it quickly became a desirable residence for the general public as well.
 The building was the first high-rise luxury apartment complex in Springfield and was likely inspired by the earlier Hickox Apartments, a 1920s complex which set standards for luxury apartments in Springfield.
 It attempted to bring the more urban lifestyle of large Midwestern cities to comparatively smaller Springfield, and early residents boasted of their access to downtown and reduced housework.
 Shortly after its construction, however, the national trend of dispersed suburban homes made its way to Springfield; as a result, the Town House was the only luxury high-rise apartment ever built in the city.
The Doubletree by Hilton, formerly known as The Crowne Plaza and before that, the Sheraton Billings Hotel, is a high-rise located in the Downtown Business District of Billings, Montana.
 It is the second-tallest building in the northern Rocky Mountain region and was the tallest from 1980 - 1985 until the completion of the First Interstate Center, also in Billings.
 Construction started on the building in 1979 and was completed in 1980; it rises 245 ft in height.
 It is used primarily for hotel space, and is the tallest hotel building in Montana.
Manchester One, formerly known as Portland Tower and previously St. Andrew's House, is a high-rise building in Manchester, England, owned by Bruntwood and let out as office space.
 The tower is located at 53 Portland Street from which it was named.
 The tower was one of the first high-rise buildings built in the 1960s and 1970s in the United Kingdom.
Bundang-gu is the largest and most populous district ("gu") of Seongnam, a major city in the Seoul Capital Area, South Korea.
 Bundang is one of South Korea's wealthiest and highest developed areas, being the nation's first and largest completely artificial city built in the early 1990s.
 Many high-rise luxury condos moved in the early 2000s, with a second planned city built in the late 2000s called Pangyo in the same district.
 Apartment prices are the second highest in Gyeonggi-do after Gwacheon and 10th highest nationwide, higher than many central Seoul districts such as Mapo-gu or Jongno-gu.
 Apartments around Pangyo Station and the high-rise luxury condos around Jeongja Station and Sunae Station rival prices in the most expensive areas in the country.
 Unlike older cities such as Seoul, Bundang has no telephone poles overground, resulting in a clean cityscape with well-designed streets.
Solitair Brickell is a high-rise under construction in the Brickell district of Miami, Florida, USA.
 It will contain 420 apartments and be about 555 ft high with 48 floors when completed in 2017.
 The building was built in the place of a ramp to a parking garage to an adjacent 1980s office building known as the Brickell Bayview Center during a wave of high-rise residential development in the Greater Downtown Miami area in the 2010s.
 The building is adjacent to Brickell City Centre, a large mixed-use development completed in 2016.
First National Bank Building (also known as the Old First and Merchants National Bank Building and BB&T Bank Building) is a historic bank and high-rise office building located at 825 East Main Street in Richmond, Virginia.

 It is a 19-story, four bay by five bay, Classical Revival style steel frame building clad in brick, limestone, and granite.
 The building features rich architectural ornament that follows the Corinthian order both within and without.
 It was the first high-rise office tower to be built in Richmond.
 The First & Merchants Bank would eventually become Sovran Bank.

 The project was announced by Majestic Resorts in February 2004, and was to be accompanied by Hilton's Conrad Las Vegas, a Conrad-branded hotel that would operate in a separate high-rise building on the same property.
 The project was initially expected to open in February 2006.
The Al Fattan Marine Towers is a complex in the Dubai Marina section of Dubai, United Arab Emirates.
 The towers are located within Jumeirah Beach Residence, a 40-tower, 7,000 unit residential and hotel development which runs alongside Dubai Marina.
 The Al Fattan Marine Towers consist of two twin 50-story towers, the Al Fattan Tower, and the Oasis Beach Tower, consisting of serviced and residential apartments which have since been sold to individual investors and homeowners.
 Both towers stand at a height of 245 m (804 ft) and a roof height of 230 m (755 ft), and are the tallest buildings in Jumeirah Beach Residence.
 Construction of both towers was completed in 2006.
 Following completion the developer, Al Fattan Properties LLC built a 12-storey office and retail building on an adjacent plot between the towers and Dubai Marina restricting views of the marina from the towers.
 In 2012 Al Fattan commenced construction of two high-rise towers on the beach in front of the towers which will largely restrict seaviews from Al Fattan Marine Towers.
 Al Fattan had earlier demolished a 10-story hotel on the site, the Oasis Hotel, which it had built about a decade earlier.
 Originally Al Fattan proposed to build a mega 97-tower building on the site to be called Burj Al Fattan, however a subsequent decision was made to split the development into two high-rise towers.
 The exact number of floors is not known as there has been no public disclosure of the project.
