This project consisted in the complete refurbishment of the indoor playground of the Alegro Alfragide Shopping Center, occupying a narrow corridor between its window shops. It was intended to secure an aesthetics similar to the one created for the Setúbal Shopping Center, with the same type of shapes and colours, but distinct and with a bold and personalized design. The big challenge was to fit large towers and tubular slides into a corridor which, although long, is quite narrow. The solution found took form as an original spiral tower connected to a higher tower through a rope tunnel.
