Outdoor Living, Reimagined Through Expert Landscape Design
Great landscape design starts with how you actually live outdoors. Before anything is built, you’ll see a clear, customized plan so every detail feels right for your home.
Patios With Purpose
We build patios that suit how you relax and gather, whether it’s a shaded terrace in Woodstock or a spacious lounge in Roswell.Front Yards That Welcome
In East Cobb, Alpharetta, and surrounding neighborhoods, we create front yard designs that feel complete with layered plantings, clean lines, and soft lighting.Backyards That Flow
From Milton to Canton, we connect outdoor kitchens, dining patios, and fire features into one natural-feeling space.Plantings That Belong
We choose plantings that thrive in Georgia’s clay and seasonal shifts, so your yard looks vibrant year-round.
“After calling O'Neill, Sam Wirth promptly called back and setup time to meet with us…A few days later, Sam e-mailed us detailed concept images (proposed plantings superimposed on top of photos he took during his initial visit - very cool!) along with detailed pricing…The O'Neill install crew arrived on-schedule and was just as professional... always on-time and cleaned up each day before leaving. The finished product was exactly what we were expecting based on Sam's plan.
Definitely looking forward to working with the O'Neill team again for our future landscaping needs!”
