As the early president of Merck & Co. Pharmaceuticals, George W. Merck is credited with developing synthetic vitamins and the first American-made penicillin. Merck, however, found his own natural remedy for life's stressors at "Sundune," the enchanting oceanfront beach cottage he built in Quogue Village during the Roaring Twenties. Sundune survived the Great Hurricane of 1938 and quickly became a gathering spot for socialites, debutantes and well-heeled financiers who left Manhattan and Brooklyn for the sun, fishing, swimming and social clubs found in already-tony Quogue. Today, Sundune -- which is desirably located "between the bridges" -- remains as magical as ever, hidden behind the hedgerow on 1.6+/- sprawling acres with 175 ft. of ocean frontage, and meticulously maintained and updated to 21st century standards by its current owners. Vintage architectural details include its original 1928 Dutch front door, exposed wood walls and beams, a sun-drenched screened porch, and even the home's original shell collection, tucked away in glass cabinets flanking the living room's wood-burning fireplace. The 3,000+/- sq. ft. home also boasts a formal dining room, powder room, laundry and pantry, and expansive renovated kitchen with Viking appliances, center island, and butler's area with wine cooler. An adjacent sitting room is perfect for casual dining and entertaining. The home's main staircase leads to two en-suite guest bedrooms and a large master suite with two oversized walk-in closets and an office/sitting room. The fourth en-suite guest bedroom is reached from a back staircase off the kitchen. There's also an outdoor changing room, shower and storage area on the side of the house by the two-car garage. Outdoor beauty can be found off the back deck overlooking picture-perfect hydrangeas, roses, peonies, and ornamental grasses. The front lawn leads to a beach plum-lined boardwalk that ends at an oceanfront sitting terrace and open air pavilion for twilight dining, meditating and sleeping under the stars. Redevelopment opportunities are abundant with a large building envelope for a new approximately 7,500+/- sq. ft. home with pool. Quogue oceanfront properties like this are rare and cherished.
