ONADUNE. Built in 1903 on the inner dune of East Hampton Village and "known as one of the most pleasantly located and costly residences" of the Village's seaside estate section. The three-story "Cottage", designed by John Custis Lawrence, remains one of the most important residences in the United States. Simply a work of artistic grandeur. Prominently, this 14,000 square foot estate has retained all of its vintage appointments throughout and is the last of its kind from East Hampton's fabled Summer Colony. As you enter the Main House you are welcomed by a grand foyer with coffered ceilings and leaded stained-glass windows that is a timeless reminder that you have arrived at Onadune. The first floor offers multiple living areas including a formal living room, formal dining room, breakfast room, sunroom for afternoon tea, morning room overlooking the English Cutting Gardens, Commercial Kitchen and a Library which was John D. Rockefeller's retreat in the summer months. The second floor is highlighted by the Master Suite which includes two fireplaces, a sitting alcove, dressing room, oversized walk-in closet room and a sumptuous Master Bath displaying marble craftsmanship throughout. Five additional bedrooms and three baths and a laundry room complete the second floor. The third floor greets you at an open sitting room which allows for a quiet book or a place to simply relax, a Junior Master Suite which includes its own sitting area, private bath and walk-in closet, three additional bedrooms and two bathrooms along with two original stairwells complete the third floor. The lower level, which is actually on grade, is an incredible reminder of the vintage of Onadune. The original Carriage Way of the house remains and offers parking for up to seven vehicles. Also included is a wine room, dish room for the formal dishware of the house, potting room easily accessible from the cutting gardens and a half bath. The replica Pool House is an architectural gem.
