Perched atop a scenic vineyard in Sonoma County’s historic Alexander Valley, the Soda Rock Project embodies California Modernism. Lush vegetation, expansive outdoor spaces, and a natural wood facade create a sophisticated yet comfortable retreat, blurring the lines between indoor and outdoor living. The left wing of the house, clad in charred Accoya®—a specially treated wood known for its exceptional durability and resistance to the elements—overlooks an infinity pool that seems to melt into the sun-drenched vineyards beyond. The wood tones complement the lush greenery and mimic the textures of nearby grapevines and river streams.
The Soda Rock Project’s exterior features a CUSTOM charred Accoya® wood cladding, crafted using the ancient Japanese Shou Sugi Ban technique by reSAWN TIMBER co. This process enhances the wood’s natural durability and creates a rich aesthetic, ensuring longevity for exterior applications. The charred layer over Accoya® wood offers exceptional weather resistance and dimensional stability, making it an ideal choice for this location.
Project Needs: Inspired by reSAWN TIMBER co.’s Shou Sugi Ban product line, the architect met with a specification consultant to delve deeper into our offerings. After reviewing several species and finish options, Accoya® emerged as the ideal choice to fulfill the architect’s vision for the project.
Project Solutions: Zimmerman Architects ordered a variety of samples and a 30 sq.ft. mock-up to review several Charred Accoya® products. Through careful observation and discussions with a local specification consultant, they selected a custom finish that best suited their desired aesthetics. Accoya’s warranty and natural durability were key factors in their decision.
Project Results: The meticulous selection of Accoya® wood brought the architect’s vision to life for the Soda Rock Project. By providing the client with comprehensive product information, they successfully achieved their design goals and delivered a project that exceeded expectations. We’re honored to continue this collaborative relationship and look forward to partnering with them on upcoming projects.
