The University of Canterbury School of Engineering’s Lecture Hall was completed during Guy Ngan’s time as an employee of the Ministry of Works (under Gordon Wilson), where he advised on how public art might be incorporated into architectural design.

Fondly referred to as the ‘Mushroom’ due to its appearance, the iconic Lecture theatre was one of the first buildings to appear on the Ilam campus. It was added to and modified several times during the years, and its copper roof gradually aged to a verdigris hue.

The building was damaged in a major earthquake in Canterbury on 22 February 2011, after which a decision was made to demolish it, along with Ngan’s mural.
