From Pre-fab to De-fab: Two examples of building waste

Urban issues correspondent Bill McKay looks at two different building methods that are both good at minimising construction waste. He looks at a pre-fabricated pensioner housing project in Pt Chevalier and compares it to what he calls de-fabrication - where damaged houses are moved to a different site and repaired, rather than being demolished. Bill McKay is a Senior Lecturer in the School of Architecture and Planning at the University of Auckland.
