E-Tower, Office skyscraper in Vila Olímpia, São Paulo, Brazil

The E-Tower is an office skyscraper in São Paulo that rises 148 meters high with 37 floors arranged across three distinct sections of varying sizes. The building provides approximately 51,000 square meters of workspace divided among its different volume sections.

Designed by Aflalo & Gasperini Arquitetos, the E-Tower was built with a postmodern form inspired by the Westend Tower in Frankfurt. Its original project was taller, but the intense helicopter traffic along the Marginal Pinheiros forced a reduction to 148 metres. From 2009, full-scale replicas of its underground pillars were fire-tested at the IPT, with results published in 2011.

The E-Tower's facade panels combine window frames with external granite cladding, a pioneering unitized system in Brazil. Its design was inspired by the Westend Tower in Frankfurt, and the building ranks as the fourth most modern skyscraper in São Paulo. The 10-metre-high lobby is another feature visitors notice.

The building has 17 elevators that efficiently connect the office floors and handle high traffic volumes. Visitors and tenants can use the underground parking available across four levels.

The lobby rises 10 metres from floor to ceiling, a height made possible by concrete reaching 125 MPa on site, a world record for coloured concrete. Engineers from the University of São Paulo and ABCP took part, and the mix was later fire-tested at IPT on full-scale twin pillars.
