Simon and Johann discuss the gap between design and manufacture—and how bridging this gap unlocks greater productivity in construction. Johann explores why simply investing in bigger factories or new technology isn't the answer, and why modern high-performance buildings need to be designed with manufacture and assembly in mind from the outset.

They discuss the potential of panelised prefabrication and Design for Manufacture and Assembly (DfMA) to improve productivity, quality and on-site efficiency, as well as the role of [OSM3604®](www.osm3604.nz) in supporting a more consistent approach to high-performance timber construction in New Zealand. Johann also shares his perspective on what it will take to make high-performance housing more scalable, more mainstream and more cost-competitive.

Special Guest: Johann Betz.

Drawing on his own experience building and living in a SIPS Passive House, Toby highlights how construction decisions can improve comfort, energy efficiency and indoor health. He also discusses why builders should look beyond minimum building code requirements when delivering better-performing homes. Toby emphasises the value of collaboration between builders, architects and clients in achieving successful high-performance construction outcomes.

Special Guest: Toby Tilsley.

In this episode, Jeff explains why even small changes to inspection processes can have significant impacts and discusses the factors driving higher inspection failure rates during periods of rapid construction growth.

He also explores the role of technology in improving quality assurance, including the benefits of remote inspections and digital tools such as the BRANZ Artisan app. The conversation touches on both the opportunities and challenges of modular construction in New Zealand, before highlighting the importance of ongoing education, compliance, and raising standards across the building industry.
