- The complex was built by the United Overseas Bank Limited (UOB) as an extension of the existing UOB Plaza Two, via the construction of the new UOB Plaza One and linking the two by a podium.
- The two blocks of the complex are joined by a 45 metre long podium supported by four large square columns.
- The complex was officially opened in 1995 by then Senior Minister Lee Kuan Yew with much fanfare, coinciding with the same year in which the bank celebrated its 60th anniversary since its founding in 1935.
- The podium houses the banking hall, which is framed by a 12-metre high stainless steel tensile truss curtain wall. It also creates a pleasant public space for pedestrian movement to flow unimpeded from Raffles Place to the Singapore River.
