Vietnamese architect Vo Trong Nghia’s installation in Sydney announces itself with a sweet, smoky smell that, on an early morning visit, almost induces hunger pangs. Green Ladder is constructed from bamboo that has been soaked and smoked to ensure durability, producing a savoury odour. It is the fourth of the Fugitive Structures architecture series at the Sherman Contemporary Art Foundation. Vo’s firm produces distinctive architecture, helping return natural materials to urban environments. Green Ladder, a 4m structure with pots of Australian natives, is a simplified demonstration of an architectural practice that also makes elaborate bamboo canopies and domes for halls, restaurants and resorts.
