Profile
Structural Engineering for the Modern Built Environment
Structo Design is a California-based structural design firm dedicated to bridging the gap between architectural ambition and technical reality. We believe that the most successful projects are those where engineering is integrated into the design process from the very first sketch. By combining deep technical expertise with a commitment to clear communication, we deliver structural solutions that are as efficient and cost-effective as they are resilient.
Our Approach
We approach every project with a focus on adaptability and precision. Engineering is not just about meeting code; it is about finding the most logical and elegant way to support a vision while navigating the constraints of site, budget, and material performance. We partner with architects, builders, and owners to turn complex challenges into streamlined, buildable designs. Our goal is to provide a foundation of confidence for our clients, ensuring that every structure is optimized for safety, longevity, and ease of construction.
Core Services & Markets
We provide comprehensive structural design and analysis across three primary sectors, utilizing advanced 3-D modeling and site-specific performance studies to ensure excellence in every detail.
- Residential: We specialize in the unique demands of California residential design, from custom single-family homes and high-end modern estates to intricate remodels and additions. Our designs focus on seismic resilience and the thoughtful use of materials—such as timber, steel, concrete and high-performance engineered wood—to complement the architectural character of the home.
- Commercial: Our commercial work emphasizes versatility and long-term value. We design structural systems for office, retail, and mixed-use spaces and tenant improvements that maximize open floor plans and prioritize future flexibility. We balance technical performance with the economic realities of commercial development to keep projects on track.
- Public Works & Civic Infrastructure: We are proud to contribute to the community through the design of durable public assets. Our experience includes parks and recreation, community and educational centers, bridge abutments and boardwalks, city beautification projects, and essential infrastructure, where we prioritize durability and sustainable engineering practices to ensure these structures serve the public for generations.
Construction Support & Field Coordination
The quality of a structure is defined by how well it is built. At Structo Design, our work extends far beyond the delivery of a permit set. We serve as an active resource for contractors and owners throughout the construction phase to ensure the design intent is realized accurately and efficiently.
Our construction support services include:
- Constructability & Value Engineering: Proactive reviews to identify potential field issues before they arise, offering material and system optimizations that save time and reduce costs.
- On-Site Observation: Critical milestone inspections to verify that foundations, framing, and seismic connections are installed according to the high standards of our specifications.
- Project Administration: Responsive handling of submittals, shop drawing reviews, and RFIs to keep the job site moving without delays.
- Site-Specific Problem Solving: Providing practical, real-time engineering solutions for unforeseen site conditions or material substitutions, ensuring structural integrity is never compromised.
