O’Neill Landscape Design creates private gardens that overflow with life. We design public recreation areas that protect nature and encourage use, and we restore troubled ecosystems to states of balance and health.

Our work in landscape planning and design spans more than two decades of experience. During this time, we’ve gained expertise in a wide variety of residential, commercial, and public projects—from small backyard gardens to large woodland campgrounds.

If there’s a philosophy behind our work, it’s to balance the needs of people and nature. We listen attentively to our clients and carefully analyze outdoor sites to create landscapes that are beautiful, cost-effective, and sustainable.

Based in Vancouver, Washington, O’Neill Landscape Design provides on-site services to clients located throughout the greater Portland/Vancouver area. We also offer affordable online planning and design services across the U.S
