Castro Valley Landscape Design & Construction
Transformation Construction & Design is based right here in Castro Valley. Owner Louis Siegel lives here, raises his family here, and has spent more than 20 years designing and building landscapes across the East Bay. When you hire us, you're working with a local company that knows these hills, this soil, and this community.
Built for Castro Valley Properties
Many Castro Valley homes sit on slopes, with clay soil and yards that are hard to use. We specialize in turning those spaces into level, usable, low-maintenance outdoor living areas.
Moss Rock Retaining Walls
Hold back hillsides and create flat, usable ground. About 90% of the walls we build are natural moss rock.
Patios, Walkways & Steps
Safe, easy access around sloped yards in pavers, flagstone, and concrete.
Drainage Solutions
Move winter rain away from your home, walls, and hardscape.
Drought-Tolerant Planting
Natives, decorative rock, and drip irrigation that cut water use and upkeep.
Turf & Putting Greens
Low-maintenance green space for kids, pets, and entertaining.
BBQ Islands & Outdoor Living
Custom BBQ islands, decks, fire pits, and gathering spaces.
See It Before We Build It
Most of our projects start with a custom 2D or 3D design, so you can see your finished yard before construction begins.
