The tower was first designed by Pritzker Prize laureate Kevin Roche in 1997. In 2017, the tower was re-envisioned by Pritzker Prize laureate Thom Mayne, who designed a metal coat of interlinking window modules to clad the tower. The tower has an elliptical structure, which reflected the curvilinear frontage of Temasek Avenue. Similar to its neighbour Millenia Tower, the 360 degree windows and large floor plates provide better space efficiency. Most of the offices have good views of the
city area of Singapore. The contractor designed special formwork system, to suit the curved profile of the
facade. The column, wall and facade were all constructed in the same operation by using the specially designed formwork. Telescopic table formwork system was used for the construction of the beams and floor slabs. The use of system formwork produced a high quality finish, which eliminated plastering. In fact, all the components were skim-coated. To clad up the building,
granite cladding and a curtain wall were used. The curtain wall, which has a total area of , was standardised to six different panel sizes. Off-site fabrication of these wall system made installation faster. This reduced the number of site labour. The tower is crowned by a twelve metre high ornamental trellis. This complements the adjacent pyramid atop Millenia Tower. == Amenities ==
