It was completed in 1996 and houses the headquarters of Siam Commercial Bank, as well as other office tenants and retail space.
The complex occupies 52 rai (8.3 ha; 21 acres) on Ratchadaphisek Road, near Ratchayothin Intersection, and was designed by Thailand-based American architect Robert G. Boughey.
It was one of the first buildings in Thailand to employ intelligent systems to optimize energy efficiency, and was unique at the time for the development of an entire complex as a single project under a common overarching design.
[4] Designed with the goal of being an integrated city environment,[1] the complex also features a large number of shops and restaurants in its podium mall, and is a popular destination for people who live and work in the area.
In February 2015, a fire damaged three floors of the bank headquarters and killed one firefighter,[6] while in March 2016, a chemical accident killed eight people (seven contractors and a security guard) servicing a fire-suppression system in a document vault in the building's basement.
