The former Attorney-Generals Chambers, which is now part of the Parliament Building, was originally built in the 1880s, though the current design dates from 1906. The first building on the site seems to have been completed in 1839, as an annex to Maxwell's House (also known as the former Parliament House), which is considered the oldest surviving building in Singapore.
The Bank of China building was built in 1954 by architects Palmer & Turner. It was one of the first towers in the central business district and the first to include central air-conditioning. The same architects were behind similar towers for the Bank of China in Hong Kong (1952) and Shanghai (1937).
The Asia Insurance Building was built in 1953-55 to a design by architect Ng Keng Siang. At 87 metres, it was the tallest building in Singapore at the time. It was converted to serviced apartments in 2008 and has been renamed Ascott Raffles Place.
UOB Plaza was completed in 1995 to a design by Japanese architect Kenzo Tange. It consists of two towers joined by a podium. The earlier tower is from 1974 but was redesigned as a smaller twin to UOB Plaza 1, which became the second tower in the CBD to reach 280 metres in 1992. The Bonham Building was one of the earlier buildings on the site of the smaller UOB Plaza 2.
