Designed by the internationally acclaimed William / Kaven Architecture, Royal III stands as one of the West Coast’s most exclusive residential offerings—where modern design meets wild nature. Whether you're seeking a refined family sanctuary or a striking retreat for grand-scale entertaining, Royal III delivers both modern luxury and coveted seclusion, just minutes from the city core.Flooded with natural light and framed by sweeping terraces, the home offers uninterrupted views of mature forest and direct access to a web of lush hiking trails. The architecture blurs the line between indoors and out, evoking the experience of floating among the trees.Anchored by a steel-and-wood structural frame and wrapped in bronze-black panels that echo the surrounding landscape, the residence is a bold architectural statement. A dramatic cantilevered overhang shelters the entryway and carport, crowned with a living green roof visible from the Primary Suite.Spanning two floors plus a daylight basement and a two-car garage, Royal III is not just a home—it’s a sculptural experience in light, form, and function. A rare find for those who demand design-forward living in a tranquil, private setting.
