Projects:​

1. Comprehensive Hempcrete Training

• Location: Parkdale, OR

• 7-day immersive program


• Project Focus: Hemp-lime design systems and installation of interior hemp-lime walls on a 2,400 square foot home.

• 
Season: Early Spring


• Description: Participants will gain a comprehensive understanding of hemp-lime construction. Topics include an in depth analysis of the design and engineering of wall assemblies, formwork setup, mixing protocols, tamping techniques, curing behavior, moisture management, and how hemp-lime integrates with various framing systems. This training takes place within an active build, providing real-world exposure to sequencing, site logistics, and material handling.

​

2. Comprehensive Hempcrete Training

• Location: Underwood, WA

• 7-day immersive program


• Project Focus: Installation of both exterior and interior hemp-lime walls on an 1,800 square foot home

• 
Season: Early Spring


• Description: Another comprehensive training in hemp-lime construction designed to mirror the full educational experience of the Parkdale workshop while offering expanded hands-on application. Alongside the complete lecture series on hemp-lime building science, design principles, and construction methodology, participants will work directly on both exterior and interior hemp-lime wall assemblies on a beautiful full-scale hempcrete home in Underwood, Washington. This workshop places particular emphasis on detailing hemp-lime systems for exterior exposure, including strategies for air and moisture management, thermal performance, and long-term durability across a range of climate contexts. Participants will gain technical insight into best practices for formwork, mixes, installation sequencing, curing conditions, and integration with adjacent building systems. This training is ideal for anyone seeking a comprehensive and practice-oriented understanding of hemp-lime construction, whether entering the field for the first time or advancing toward professional-level competency.

​

3. Finish Lime and Finish Clay Plaster Training

• Location: Parkdale, OR

• 5-day immersive program


• Project Focus: Finish lime and finish clay applications

• Season: Mid Spring

• Description: This training teaches fine finish techniques including traditional lime finishes, clay finishes, polishing methods, surface refinement, natural pigments, and aesthetic detailing. Ideal for homeowners and craftspeople interested in high-quality finishes with natural plasters.

​

4. Clay and Lime Base-coat Plaster Training 

• Location: Underwood, WA

• 5-day immersive program


• Project Focus: Exterior base-coat lime and interior base-coat clay plasters

• 
Season: Late Spring


• Description: This workshop covers surface preparation, mixing, substrate conditions, application techniques, and the performance science behind natural plaster materials. Participants will learn to install durable, vapor-open clay base coats that pair effectively with hemp-lime and other natural wall systems. The key focus of this training is developing the techniques and judgment required to produce flat, plumb, high-quality wall surfaces that are properly prepared for finish plaster. Through guided instruction and hands-on practice, participants will learn how to prepare surfaces, and manage plane corrections, edge conditions, and trowel techniques that result in professional-grade base coats ready for the next layer of refinement.

​

5. Finish Lime and Finish Clay Plaster Training 

• Location: Underwood, WA

• 5-day immersive program


• Project Focus: Finish lime and finish clay applications

• Season: Summer

• Description: This workshop is the second in a two-part plaster training series and builds directly on the skills developed in the Base Coat Plaster Workshop. In this advanced training, participants move from foundational wall preparation into the refined craft of finish plasters. The curriculum covers traditional lime and clay finish techniques, surface polishing and compression methods, natural pigments, aesthetic detailing, and the subtleties that transform a well-prepared base coat into an exceptionally smooth, expressive final surface. Ideal for homeowners, builders, and craftspeople who want to deepen their mastery of natural finishes, this workshop provides the hands-on experience and technical nuance required to execute high-quality interior plaster work with confidence.
