Thai architect Sumet Jumsai designed the Robot Building for the Bank of Asia, which was acquired by United Overseas Bank in 2005. He had been asked by the Bank of Asia's directors to design a building that reflected the modernization and computerization of banking and found inspiration in his son's toy robot.
Sumet wrote that his building "need not be a robot" and that a "host of other metamorphoses" would suffice, so long as they could "free the spirit from the present intellectual impasse and propel it forward into the next century". He wrote that his design might be considered post-high-tech: rather than exhibiting the building's inner workings, he chose to adorn a finished product with the abstractions of mechanical parts. His building, he argued, struck against the 20th century vision of the machine as a "separate entity" often "elevated on a pedestal for worship" and, by becoming "a part of our daily lives, a friend, ourselves", cleared the way for the 21st century amalgam of machine and man. The building was completed in 1986 at a cost of US$10 million.By the mid-1980s, architectural modernism had faded in Bangkok; this building is one of the last examples of the style.
