Staircase of the Tivoli Av. Da Liberdade Hotel Sky Bar
Gravidade conceived and designed the steel staircase for the main access to the Sky Bar at the Tivoli Avenida da Liberdade Hotel, in Lisbon. This structure was part of the renovation work on the aforementioned roof-top, located on the top of the building.
It is a helical steel staircase followed by a straight walkway that connects the lower level to the upper level of the roof. The total span (measured on the axis) is 14.76m. The useful width is 1.40m.
The carbon steel structure is finished with metallization and painting. The steps and walkway are covered in wooden decking.
