Welcome to The Treehouse at Wales Pond — a breathtaking 8,000+ SF sustainable retreat, custom built in 2015 and privately set on 2.83 acres along the water’s edge. This architectural masterpiece fuses Japanese and Spanish influences with organic materials, offering pond views from nearly every room. Expansive glass walls open onto sun-drenched terraces, effortlessly merging indoor and outdoor living. Every space reflects intentional design, from the vaulted great room with its custom steel fireplace and floating staircase, to the first floor primary suite with a Smart Glass solarium bath, to the tranquil Yoga studio with Tatami mats. The gourmet chef’s kitchen impresses with multiple prep areas and sinks, an industrial hood with gas cooking, a Sub-Zero refrigerator, dedicated freezer and ice maker, and a gracious butler’s pantry with ample storage and cabinetry. A rare dumbwaiter connects the levels, allowing meals to travel from the kitchen to any floor with ease. This exceptional home offers 4–6 bedrooms, 6 full baths, a spacious media room, a lofted library, and a full in-law suite on the lower level with private entrances and dedicated mudroom. An interior stair lift and a private tunnel to the outdoor amenity areas add rare convenience and flow. Outside, a true oasis awaits: a fully fenced, heated pool and jacuzzi, a turfed yard, and a fire pit with pizza oven overlooking Wales Pond. Private trails through the abutting conservation land lead to the village of Marshfield Hills — home to Genny’s Ice Cream — while the pond itself is ideal for kayaking, paddleboarding, fishing, and other water activities. A true sanctuary, ideally located just minutes to the Atlantic coast.
