[1] TRX was planned during the era of the sixth Prime Minister, Datuk Seri Najib Tun Abdul Razak and it is a strategic enabler of the Malaysian government's Economic Transformation Programme (ETP).

The master plan includes a total of 26 buildings and over 21 million ft2 of Gross Floor Area (GFA) spread across the office, residential, hotel, retail, F&B and cultural offerings.

The Royal Selangor Golf Club is across Jalan Tun Razak, as well as RHB Bank's national headquarters and Zouk KL.

The central park will connect all the buildings within TRX using tumbling, terraced greenery, water features and shaded sections.

[17] Other well-known retailers that will make their presence at the mall include Kiehl’s, Diptyque, Coach, Tiffany & Co, Fendi, Hublot, Dior, Burberry, Saint Laurent, Gucci, Chanel, Louis Vuitton, Guerlain, Rimowa, Hublot, Lancôme, Bell & Ross, Steve Madden, Gentle Monster and many more.

[18] In December 2022, the project director of The Exchange TRX, Mitch Wilson, said that the mall will include more than 400 stores across four retail levels.

[20][21] Following the partnership with Lendlease, TRX announced its Sale and Purchase agreement with the Mulia Group to develop the Signature Tower.

The new Prudential headquarters, located adjacent to TRX's main pedestrian gateway from the Bukit Bintang area, incorporates the traditional Malaysian element of Tengkolok Diraja (a Malay royal headgear).

With 51,018 m2 of Grade A office space, the building will house all of Prudential's life insurance and asset management businesses in Malaysia under one roof.

In April 2017, the bank signed an agreement to acquire a 54,266 sq ft plot of land on which it will build its headquarters, for a total cost of RM555 million.

The building, expected to be completed by the end of 2020, features a banking hall, auditorium and convention facilities, and access to the TRX MRT station via a sunken plaza, spacious outdoor terraces and sky gardens.

[42] In January 2019, Lembaga Tabung Haji sold its plot of land at a premium to Urusharta Jamaah Sdn Bhd, a company owned by the Malaysian government.

[45] A key component of TRX's sustainability framework, the district is supported by Veolia's onsite cooling system to reduce energy consumption and wastewater recycling treatment to conserve water, as well as a large urban public green realm for Kuala Lumpur.
