Don't let this once-in-a-generation waterfront masterpiece pass you by. Rarely does a property combine an architect-caliber, modern-transitional residence, and an irreplaceable true deepwater dock, located within walking distance of two of the Seacoast's most beloved downtowns. Set directly on the Piscataqua River with sweeping views of Portsmouth and three iconic bridges, this 3,200-square-foot custom home was designed by Amy Dutton Home and built by Haven Hill Builders -- conceived from the water in. Outdoor space is the property's crown jewel. An expansive 24/7 deepwater dock is outfitted for serious entertaining and boating alike. A 40-foot float accommodates larger vessels and the Japanese-style hibachi kitchen is built for waterside cooking. A private cabana with half-bath creates a self-contained retreat right on the water. Three bedrooms and two-and-a-half baths unfold across a light-filled, open-concept layout. The kitchen is a showpiece, anchored by a Thermador range and a waterfall-edge quartz island with a built-in insert for fresh herbs or party ice. Custom lamp-black cabinetry with fluted glass inserts adds understated drama to the main living area. The primary suite is framed by custom doors that open to a rooftop-terrace with water views for effortless indoor-outdoor living. A dramatic third-floor flex space is wrapped in a triple-glazed curtain wall of glass overlooking the Portsmouth skyline -- the home's defining architectural feature. Above the garage, a light-filled studio with its own water-facing windows provides flexible space for work or art. Outside, a granite patio and firepit overlook the water, surrounded by coastal gardens cascading toward the shoreline. Built to a high-performance standard with a steel substructure, continuous exterior insulation, and 98%-efficient heating and cooling -- extraordinary design meets extraordinary durability. This is an extremely rare opportunity to acquire one of the Seacoast's signature propertie
