The 95-floor building is topped with a 65-meter, 12-storey high illuminated crown making it 445 m (1,460 ft) tall. The tower will have a net lettable area of 2.6 million square feet (240,000 square metres) and is benchmarked against similar buildings in large international financial centers, such as London’s Canary Wharf and The Shard, New York’s Freedom Tower, and Shanghai IFC.

As of January 2018, more than half of the Exchange 106’s floor space has been taken up by large tenants, predominantly local financial institutions, each taking up between 2 and 8 floors, which have column-less floor plates ranging from 28,000 to 34,000 sq ft (2,600 to 3,200 m2).

The skyscraper was first conceptualised when TRX was controlled by 1Malaysia Development Berhad (1MDB), a fund owned by the Malaysian government. On 13 May 2015, 1MDB Real Estate Sdn Bhd (1MDB RE), the master developer of TRX, and the Mulia Group announced that, through Mulia Property Development Sdn Bhd, they had signed a Sale and Purchase agreement for the development rights of the plot of land for the Exchange 106 (then known as the Signature Tower), with the land transacted at a value of RM665 million. Ground work on the Exchange 106 plot commenced on 1 March 2016, with the mat concrete foundation laid in May 2016 (see “Progress” section below).
