The HMD Consortium hired a team of urban architects led by Marcelo Aciolly Fragelli, who created the station designs.

In the central region, the Clóvis Beviláqcua station was designed by architects Roberto McFadden and José Paulo de Bem; however, as it is the largest station in the network (housing the North-South and East-West lines and a third line to Santo Amaro- which ended up not getting off the ground) this project was conceived slowly.

On September 26, 1975, trains on the North-South Line were already passing under the works at Sé station, which were still slow, due to the manual demolition of Palacete Santa Helena.

A Brazilian explosives manufacturer refused to provide material for the demolition fearing he would be held responsible for a major tragedy.

CDI technicians installed 777 explosive charges in the Wilson Mendes Caldeira Building totaling nearly a thousand pounds.

In the early hours of 16 November 1975, the surroundings of Praça da Sé were filled with thousands of spectators to watch this unprecedented feat in the city.

It also consists of a distribution mezzanine and two overlapping levels with two lateral platforms and a central one (one set per line) with an exposed concrete structure and openings for natural lighting.
