Beach Hampton is Amagansett's most coveted, private beach community-commonly known as Amagansett Dunes, or simply 'the Dunes'-where the roar of the Atlantic tangles amidst the windswept landscape, and private pathways lead to sparsely populated stretches of white sand. This home is one of the treasured original summer colony homes-built after the '38 hurricane-remain tucked behind mature landscaping. Enter 26 Gardiner-not only part of the original colony, but a compound-where Arthur Miller and Marilyn Monroe frequented dinner parties in the late 1950s. Here, the preserved beach-cottage charm comingles with minimalistic restraint, resulting in a symphony of elegantly livable historical beauty. The main home, with 3bd and 2.5ba, features a fireplace with seabird tilework by noted ceramicist Carol Janeway-a friend of the previous owner, socialite Mary Bass (Marilyn Monroe was also a patron of Janeway's work, with 5 of her pieces surfacing in Monroe's final estate auction). Off the light-filled living room, the dining area opens to a shady outdoor dining pergola, perfect for casual summer entertaining, while the beautifully renovated kitchen opens to a central courtyard connecting the main house to the guest house. Both structures have been renovated with endless historical consideration showcasing immaculately curated and preserved fixtures and details-hardware, shiplap, exposed beams, smooth painted floors, and a color palette inspired by the surrounding ocean landscape. The guest cottage, with 2bd and 1ba, features an eat-in kitchen, outdoor shower, and a lovely hidden covered porch, perfect for cool drinks on summer afternoons. With room for expansion, a permit pending for an oversized 18' x 30' pool, plus brand-new infrastructural upgrades-expanded parking, irrigation system, deer fencing, HVAC, washer/dryer, pantry, septic with nitrogen system permit pending, updated wetland flagging, plus electrical and plumbing updates-this offering is a once-in-a-lifetime opportunity to attain an inimitable and iconic property.
