The Huff ‘n’ Puff Passivhaus

Huff ‘n’ Puff is a family-run straw bale construction company based out of Ganmain, providing design advice and construction. They also run workshops relating to straw bale building in NSW.

Huff ‘n’ Puff is considered by its peers as a leader and expert in this fledging industry. Founder John Glassford will tell us how the company has developed a unique and ecologically sound, structural super-insulated panel building system known as “Sit-ups” (super-insulated tilt-up panel system).

These straw bale panels can be put into place by two people. The structural panel system provides a cost-effective building system based on an environmentally responsible manufacturing process.
