The Build Back Smarter case studies

Back to Existing Homes


The Build Back Smarter pilot project used case studies to test the approach and ease of upgrading homes during earthquake repair.

Although the project aimed to upgrade ten homes, the slowness of the repair process in Christchurch meant that only six homes were upgraded as part of the Build Back Smarter pilot.
