Landscape Design & Build — Done Right

Transformation Construction & Design was founded on a simple belief: exceptional outdoor spaces begin with thoughtful design, honest communication, and quality craftsmanship.

Founded by Louis Siegel, Transformation Construction & Design combines over 20 years of landscape construction and design experience with a hands-on, client-focused approach. Having helped homeowners complete thousands of landscape projects throughout the East Bay and Tri-Valley, Louis understands that successful outdoor spaces require both creative vision and practical construction expertise.

As a Castro Valley resident, husband, and father of two, Louis takes pride in serving the same communities he calls home. He believes outdoor spaces should do more than improve a property's appearance. They should create places where families can gather, entertain, relax, and make lasting memories for years to come.

Beyond his work, Louis enjoys supporting local schools, youth sports, and community events throughout the East Bay. Whether sponsoring local programs or coaching his children's teams, giving back to the community is an important part of who he is and reflects the same values he brings to every project.

From custom landscape designs and drought-tolerant gardens to patios, outdoor living spaces, lighting, synthetic turf, and complete property transformations every project is approached with attention to detail and a commitment to quality. Clients work directly with Louis throughout the design, planning, and construction process, ensuring clear communication, accountability, and a seamless experience from concept to completion.

Unlike larger companies where projects are often passed between departments, Transformation Construction & Design provides a more personal approach. Louis remains actively involved throughout the project, working closely with crews, overseeing construction, answering questions, and helping ensure the finished product reflects the original vision. We take the time to understand your goals, develop solutions tailored to your property, and guide you through every step of the process.

We believe our responsibility doesn't end when construction is complete. We take pride in our workmanship, stand behind our projects, and are committed to addressing concerns promptly and professionally should they arise. Our goal is simple: deliver a finished product we would be proud to have in our own home while providing the level of service we would expect for our own family.

Proudly serving Castro Valley, Dublin, Pleasanton, Livermore, San Ramon, Danville, Alamo, Hayward, San Leandro, and surrounding East Bay / Tri Valley communities.
