The building has 35 floors above ground level,[4] and is originally planned to be the first of three towers for the Ayala Triangle.

Plans for the construction of the two additional buildings did not materialize until 2021, due to the completion of the Ayala Triangle North complex.

Other institutions that headquartered at Ayala Tower One include the primary trading floor of the Philippine Stock Exchange (Until February 2018) and Banco de Oro Universal Bank (BDO).

Tower One & Exchange Plaza is located near two other famous buildings, the headquarters of Bank of the Philippine Islands, an Ayala Corporation company, and the former main office of Insular Life.

Ayala Land was hoping that the Philippine Stock Exchange would reconsider its plan.
