Who we are
Hi, I’m Jon Koster, owner of G3 Build. I started this company with a simple idea: create outdoor spaces that families can truly enjoy. Whether I’m in the mountains, at the beach, or in my own backyard with my wife and three kids, I’ve always found that the best memories are made outside. That same joy of being outside is what drives the work I do for my clients.
Our Vision
At G3 Build, we design and build functional outdoor spaces that bring families together and make every home more enjoyable. Guided by engineering precision and attention to detail, we create backyards that inspire connection and lasting memories.
Building Backyards, Creating Memories.
Our Mission
Our mission is to inspire connection to the outdoors by creating functional, high-quality landscapes where families can gather, relax, and make lasting memories.
Why Choose Us
With a background as a Professional Engineer, I approach every project with precision and care. From detailed planning to installation, no element goes unnoticed. Whether it’s a full landscape design or smaller updates like mulch, irrigation, or planting, G3 Build is committed to craftsmanship and lasting results.
