London's first skyscraper was designed to mimic a bank's logo from the sky.
In short: Tower 42, formerly the NatWest Tower, redefined the London skyline in 1980. Its unique cantilevered structure, designed to resemble the bank's three-chevron logo, was a feat of engineering that once held the title of the world's tallest cantilever. Today, it remains a landmark of innovation and resilience in the City.
Completed in 1980, Tower 42 was London's first true skyscraper, standing 183 metres tall. Its design by R Seifert & Partners was controversial, as it defied existing height restrictions and required the demolition of historic 19th-century bank buildings. To secure approval, the architect famously presented a choice between his preferred single-tower design and a less aesthetic alternative, successfully guiding public opinion toward his vision. The final structure was built around a massive central concrete core, with 42 of its 47 levels cantilevered outwards to maximize space while respecting adjacent air rights.
The building was packed with cutting-edge technology for its time, including double-decked lifts and sky lobbies—both firsts for the United Kingdom. It also featured an automated internal mail delivery system and computer-controlled climate management. Despite these advancements, the tower's design limitations were quickly apparent; the cantilevered floor plates were restrictive, forcing the bank to keep its primary trading operations in older, more traditional office spaces nearby. It was never fully utilized for the high-intensity trading floors the bank initially envisioned.
The tower's history is marked by significant trauma and transformation. In 1993, a major truck bomb in the Bishopsgate area caused over £1 billion in total damage to the vicinity, leaving the tower severely compromised. Refurbishment cost £75 million and required a complete recladding of the exterior. Following this, NatWest opted not to reoccupy the space, eventually selling the building in 1998. Renamed Tower 42, it transitioned into a multi-tenanted office space, later acquired by South African businessman Nathan Kirsh in 2011 for £282.5 million. Today, it serves as a general-purpose office building, featuring modern LED lighting systems that can display complex graphics across its upper levels.
The tower's legacy is defined by its engineering, which for a time made it the tallest cantilevered structure globally. While it was superseded as London's tallest building by One Canada Square in 1990, it remains a significant architectural reference point. Its resilience, having survived both the 1993 bombing and a 1996 fire during its own restoration, underscores its enduring presence in the City of London.
