Innovation, Sustainability and 125 Years of Craft with JSC

Send us a text

In this episode, Janey and Rebecca sit down with Lee from JSC Timber — a family business with roots going back 125 years. Based in Riverhead, Auckland, JSC has become a trusted name in architectural timber across Aotearoa. They’re best known for Western Red Cedar and their range of thermally modified timbers, chosen for both performance and beauty in residential and commercial projects.

Lee talks about how timber is changing — from new profiling and coatings to introducing thermally modified species like Amber and Taxon. He also shares how JSC works alongside PSP, widening their offering from timber into plastics and surface finishes to create full building envelope solutions. With sustainability at the centre of everything they do, Lee reflects on the future of timber, the challenges of sourcing, and the satisfaction of seeing a project completed.

In this episode you’ll hear about:

• What makes JSC stand out — from their products to their architectural support

Reflections from Lee:

• “Thermally modified timber is a game changer — durable, chemical-free, and beautiful.”
  
  
• “We’re not just selling timber. We’re helping bring people’s visions to life.”
  
  
• “Profiles are like fashion for your walls — shape and function together.”
  
  
• “Coating is everything. It protects the timber and shows off its character.”
  
  
• “Sustainability isn’t just about the product — it’s about the people, the processes, and the future.”
