Sap was built on City Hall Square in Paris for the Charlois Group, to celebrate the International Forest Day with the French National Office for Forests in March 2019 (watch the film of Sap being built here).
Sap features a double helix spiral stairway, symbolizing rising and descending sap. A small feat: we assembled the work in 3 days, disassembled it in 48 hours and rebuilt it later in Murlin, France, headquarters of the Charlois Group. This movie shows the later adventure.
