The first highly illustrated, comprehensive guide to light straw clay - a high performance, low-impact, durable building material

Light straw clay - straw mixed with clay slip - is a versatile, easy-to-use wall building material. Also called "slip-straw", its durability has been proven in beautiful, centuries-old buildings across Northern Europe and in modern high-performance buildings in North America.

Building code compliant in the US and using "waste" materials with high insulation value and excellent moisture handling qualities, it's both high-performance and low-impact. Yet until now, there has been no practical guide to using the material in a wide variety of construction and renovation projects.

Distilling decades of experience, Essential Light Straw Clay Construction is a fully illustrated step-by-step guide, ideal for both the DIYer and professional designer and builder alike. It covers:



Material specifications, performance, and when and where to use it
