Project Overview: In the scenic landscape of Grass Valley, CA, a private homeowner sought to maximize the allowable 1,200 square feet for their Accessory Dwelling Unit (ADU). The primary vision was a highly functional, open-concept living space defined by a dramatic heavy timber aesthetic, integrated seamlessly with a large outdoor area.
The Challenge: Balancing Aesthetics, Structure, and Site Constraints The project presented a complex balancing act. The client’s desire for large spans and minimal interior posts created a significant Key Technical Difficulty in supporting the roof structure. Furthermore, the extensive, sloping lot required meticulous site planning to ensure the ADU placement accommodated a future primary residence and a planned pond, adding layers of complexity to the foundation and site services. The challenge was maintaining the right rhythm between the architectural grandeur of the timber beams and the structural engineering reality while keeping the project economically viable.
Our Innovative Structural Solution: Our firm collaborated closely with the client, translating their rough sketches into a fully permitted design package. Our innovative solution was a sophisticated timber truss hybrid design specifically engineered to support the extensive beam system and achieve the desired clear spans. We utilized standard wood framing paired with strategic, high-performance connections, including concealed blade hangers for the trusses. This approach successfully eliminated visual interruptions while delivering the necessary structural strength, preserving the clean, authentic look of the heavy timbers.
Successful Execution and Client Impact: Our comprehensive package, which included architectural and structural plans, energy calculations, and the site plan, was successfully permitted and the design phase of the project was completed on time. We were able to meet the client’s architectural desires by suggesting alternative methods and layouts that maximized the space and delivered the striking indoor-outdoor flow they envisioned. This structural creativity ultimately achieved the client’s vision for a high-value, highly livable ADU.
