27 Castle Road, Piermont, NY 10968

KoiHaus, a mid-century modern home on 3.16 acres, tucked away on a secluded road near the banks of the Hudson River—just a stone’s throw from the legendary 1890s McKim, Mead & White masterpiece, Lord’s Castle. This architectural gem is a masterclass in organic design, orchestrating a brilliant dialogue between mid-century modern aesthetics and the spiritual heritage of Japanese landscaping. KoiHaus is more than just a luxury residence; it is a living sanctuary where home and nature exist as one. The landscape is as important as the architectural design. The landscape architect designed the gardens from inside out - thru its 100 windows. There is harmony between the home's natural setting and the architectural design. The home rises from the site line as one approaches it, going past the 13 ft tall steel elephant in the front yard, that moves naturally by the wind. True to the legacy of Frank Lloyd Wright, KoiHaus utilizes clean lines and geometric shapes, that are softened by its Japanese gardens and landscape. The structure is composed of five interconnected boxes, wrapped in an exterior palette of concrete, stucco, stone, and rich hardwood, all capped by a durable, 50-year roof. What truly defines the exterior, however, is its relationship with light. Its many windows of varying shapes and sizes, framing shifting natural portraits throughout the day. Every detail leans into sleek minimalism. Broad, flat moldings complement natural stone walls, while pocket doors are utilized throughout to maximize room volume and echo Japanese sliding screens. Premium finishes include polished bluestone countertops KoiHaus' defining engineering feature is its split-foundation design. Technically it is two independent structures joined by a dramatic glass-and-steel bridge. Beneath this bridge flows a continuous, sprawling koi pond that meanders under and around the house. From almost any vantage point, residents can look out to watch Nishikigoi—the "living jewels" of Japan—swimming gracefully in their natural habitat. In Japanese philosophy, the koi represents perseverance, strength, harmony, and transformation.
