About Us

Welcome to DarkHorse Landscapes, where thoughtful design meets functional beauty. Founded by Chelsea Mills in 2020, we specialize in creating timeless, low-maintenance landscapes that blend form and function. Based in Halton Hills and Belleville, Ontario, our portfolio spans elegant residential gardens, inviting outdoor living spaces, and thoughtfully designed landscapes that enhance the way you live.

Meet Chelsea Mills

Chelsea Mills has spent a lifetime working outdoors. Growing up immersed in the equestrian world, she developed a deep understanding of outdoor spaces—not just as something to admire, but as environments that need to function seamlessly. Years of training, competing, and managing horses and equestrian facilities gave her an appreciation for durability, efficiency, and smart design, which naturally translated into her passion for landscape architecture.

Chelsea refined her expertise by earning an Advanced Diploma in Landscape Design at Fanshawe College before studying Landscape Architecture at the University of Guelph. Today, she applies her knowledge to create stunning, high-performance landscapes that work just as well in a backyard as they do on a large rural estate.

No One-Trick-Pony

At DarkHorse Landscapes, we believe every property is unique. Whether you're envisioning a serene backyard retreat, a functional outdoor entertaining space, or a large-scale property that requires both beauty and durability, we create designs that fit your lifestyle. Our work is defined by low-maintenance solutions, sustainable materials, and timeless aesthetics—ensuring your landscape remains inviting and effortless for years to come.

Low Maintenance, High Impact

Your landscape should enhance your life—not add to your to-do list. From durable hardscapes and resilient plant selections to efficient irrigation and erosion control solutions, we design landscapes that thrive with minimal upkeep. Whether it’s a private garden, a poolside retreat, or a multi-acre property, our goal is to create a space that works beautifully today and continues to do so for years to come.

At DarkHorse Landscapes, we don’t just design outdoor spaces—we create environments that enhance the way you live, entertain, and connect with nature.

High Performance Equestrian Spaces

While our roots are in residential landscape design, our expertise naturally extends to equestrian properties, where practicality and beauty must go hand in hand. With first-hand knowledge of how horses interact with their environment, we design spaces that prioritize safety, durability, and efficiency—from well-drained arenas to functional paddocks and aesthetically integrated stable yards.
