The building was later enlarged to a 26-story, 118 m (387 ft) skyscraper, making it the tallest in the city when the renovations were completed in 1912. Tenants moved in on April 1, 1912, with the building's fireproofing prominently advertised.

The Farmers Bank Building was a 27-story, 105 m (344 ft) skyscraper in Pittsburgh, Pennsylvania completed in 1902 and demolished on May 25, 1997. The University of Pittsburgh's online digital library states the building was constructed in 1903 and had 24 stories. To a generation of Pittsburgh sports fans the building is well remembered for being resurfaced in the mid 1960 in a failed rehabilitation but also fondly for a 15 story high mural of Roberto Clemente, Bill Mazeroski, Jack Lambert, Mean Joe Greene and Mario Lemieux completed in 1992 by Judy Penzer, who was killed in the crash of TWA Flight 800 four years later. For the five years the mural existed it was often the centerpiece for national networks cutting to or from games while they were in town for sporting events. Rockwell International owned the building starting in the mid-1960s and used it as its global headquarters, selling it in early 1972 and consolidating its headquarters staff in the U.S. Steel Tower blocks away.The building was imploded by Controlled Demolition, Inc. on the afternoon of May 25, 1997. In its place, a low-rise department store named Lazarus was built on the site. That building has since been extensively redesigned and now operates as a condominium development named Piatt Place.

Downtown Pittsburgh, colloquially referred to as the Golden Triangle, and officially the Central Business District, is the urban downtown center of Pittsburgh. It is located at the confluence of the Allegheny River and the Monongahela River whose joining forms the Ohio River. The triangle is bounded by the two rivers. The area features offices for major corporations such as PNC Bank, U.S. Steel, PPG, Bank of New York Mellon, Heinz, Federated Investors, and Alcoa. It is where the fortunes of such industrial barons as Andrew Carnegie, Henry Clay Frick, Henry J. Heinz, Andrew Mellon and George Westinghouse were made. It contains the site where the French fort, Fort Duquesne, once stood.

Two PNC Plaza (once known as Equibank Plaza) is a high-rise office building located in the Golden Triangle of Pittsburgh, Pennsylvania, United States. Constructed in 1976, it is 446 feet (136 m) in height and has 34 stories, making it the tallest of three buildings in PNC Plaza. In order to make room for the structure, a through street called Oliver Avenue was closed.The structure was built by Equibank, one of the Pittsburgh region's three major financial institutions, and was completed four years after and only a few feet away from One PNC Plaza, the home of their major rival (which was then named Pittsburgh National Bank). Equibank went into a sharp decline in the 1980s due to poor investments surrounding a Florida housing bubble and a series of defaulted loans from newly privatized South American companies. Simultaneously, PNC was growing and began expanding into their rival's building next door. PNC eventually not only acquired the building but also a portion of Equibank's operations (the company was merged with the smaller Integra Bank in 1992, Integra was purchased by National City Corp. in 1995, and PNC purchased National City in 2008); PNC and KeyBank currently operate many former Equibank branches.

It was the tallest building constructed in the city since Highmark Tower was completed in 1988, until The Tower at PNC Plaza was completed in 2015. It contains 326,000 square feet (30,300 m2) of office space, a 185-room Fairmont Hotel, and 28 condominium units. The $179 million ($248 million in current dollars) project created 800 construction-related jobs with a $35 million payroll ($48.6 million in current dollars). Thirteen buildings were demolished to make way for the building. Three PNC Plaza is a LEED certified green building.

Allegheny City was a municipality that existed in the U.S. state of Pennsylvania from 1788 until it was annexed by Pittsburgh in 1907. It was located north across the Allegheny River from downtown Pittsburgh, with its southwest border formed by the Ohio River, and is known today as the North Side. The city's waterfront district, along the Allegheny and Ohio rivers, became Pittsburgh's North Shore neighborhood. The area of Allegheny City included the present Pittsburgh neighborhoods of Allegheny Center, Allegheny West, Brighton Heights, California-Kirkbride, Central Northside, Chateau, East Allegheny, Fineview, Manchester, Marshall-Shadeland, North Shore, Northview Heights, Perry North, Perry South, Spring Garden, Spring Hill–City View, Summer Hill, and Troy Hill.

The Tower at PNC Plaza is a 33-story skyscraper in Pittsburgh, Pennsylvania. It is the corporate headquarters of the PNC Financial Services Group and has approximately 800,000 square feet (74,000 m2), standing 33 stories (545 feet) tall. Nearby buildings totaling 37,000 square feet (3,400 m2), were purchased by PNC and deconstructed to make space for the Tower at PNC Plaza. It is located at the intersection of Fifth Avenue and Wood Street, where PNC and its predecessors have been based since 1858. The project was estimated to cost $400 million when announced in 2011 (or $482 million today).Construction began in spring of 2012 and was completed in October 2015. The tower is one of the greenest high-rises ever built, and even exceeds the current criteria for a LEED Platinum certified building. The Tower features numerous sustainable attributes such as an operable double-skin facade, an onsite grey water reuse system, locally sourced building materials, fixtures and furniture made from recycled materials, and numerous other green strategies to substantially reduce the environmental impact of the building. Some of these features enable the Tower's heating and cooling systems to operate in a "net-zero-energy state" up to 30% of the year. This is accomplished by its innovative solar chimney, which creates a stack effect through the core of the building to ventilate excess heat without the need for mechanical ventilation. The Tower's sloped roof acts as a solar collector and is positioned facing south. The tower's "topping off" ceremony was held Tuesday, June 24, 2014, with William Demchak, PNC chairman, president and CEO, and Gary Saulson, director of corporate real estate hosting it on site. The tower officially opened on October 2, 2015.

K&L Gates Center is a skyscraper office building located in Downtown Pittsburgh, Pennsylvania. The building (long known as One Oliver Plaza and briefly as FreeMarkets Center and later Ariba Center) was completed in 1968. It has 39 floors, and rises 511 feet (156 meters) above downtown Pittsburgh. The building sits at the intersection of Liberty Avenue, Sixth Avenue and Wood Street. Facing the EQT Plaza tower across the street, it shares a city block with One PNC Plaza, Two PNC Plaza and Three PNC Plaza; this "superblock" was created by the closing of part of Oliver Avenue in the late 1960s. Located across the building is Wood Street Station, a subway station on Pittsburgh's light rail network. In 2007, the international law firm K&L Gates entered into an agreement to become the largest tenant in the building by 2010. In 2009, extensive construction began on the building lobby, the exterior facade of the first two floors and the plazas surrounding the building. The K&L Gates signage replaced Ariba at the top of the building. K&L Gates also removed a sculpture in the building's lobby in order to maintain a consistent decor. The artwork, a large enamel-on-steel mural by Virgil Cantini, has been donated to the University of Pittsburgh by the building's owner. The lobby was reopened in February, 2010. In March 2010, K&L Gates became the building’s largest tenant, having sponsored both the renaming of the building and a revitalization of the building’s ground-floor lobby, exterior entry facade and adjoining plaza.Among the building's artwork is a new, illuminated entry portal connecting the building with the street, with five "Light Columns" created by artist Cerith Wyn Evans illuminating the interior space as well as the outside plaza. These columns are complemented by the neon wall sculpture "Mobius Strip", also by Wyn Evans, at the entry reception desk. The use of light within architectural environments is a cornerstone of Wyn Evans’s practice, with this site-specific piece having been created exclusively for the K&L Gates Center.
