New York, New York (June 17, 2021) — Located in one of the most prestigious areas of Oyster Bay Cove, with panoramic water views of Oyster Bay and Centre Island, Rainbow Landing is a true Gold Coast treasure. Its legacy dates back to 1855, when original owner, Francis T. Underhill – a superb equestrian who introduced polo to Oyster Bay – purchased the property then named Boscabel. It was then sold to Horatio Seymour Shonnard, a descendent of New York governor Horatio Seymour. The current owner acquired the property in 1988. He build a new home in the Modern style and renamed the estate Rainbow Landing.
Rainbow Landing, with six bedrooms and four full baths-and-two-half baths is represented by Kathleen Coumou and Brian Meier of Christie’s International Real Estate Group, Inc., with global marketing provided by Christie’s International Real Estate.
Said Ms. Coumou: “Every room in the house affords stunning panoramic views of Oyster Bay through oversized widows. The entire house was built with the intent to enjoy the estate’s beautiful landscape and vistas both inside and outdoors.”
The setting is ultimately private, due to the thick stand of trees and hedges shielding the home from the road plus its set back position on the property. The entry opens to a drive winding up under a canopy of hardwood trees, terminating at a circular motor court.
A serene koi pond introduces the majestic wooden door, flanked on each side by two stacks of double-height glass panes and opening to a sunken living room with an entire wall of windows showcasing the endless water views. Light drenches the crisp white interiors through enormous skylights in the soaring cathedral ceiling. A double-sided two-story stone fireplace warms both this room and the adjoining den. Also on this level, with its open space floor plan, is the formal dining room, solarium-style kitchen and breakfast room. A portal off the kitchen and expansive patio off the living room, both overlooking the bay and the estate’s private pond, are ideal for alfresco entertaining and dining.
A dramatic spiral staircase ascends to the second level. The oversized primary suite includes a bath with steam shower and large walk-in closet. Two separate decks overlook the property and the bay beyond. Adjacent to the primary suite are two additional bedrooms and one full bath. A floating walkway, overlooking the first floor and with still more water views, connects the bedrooms to an enormous open office space with more cathedral ceilings with a row of skylights.
Completing the home is a maid’s quarter, five-car garage, finished basement and an elevator serving all three floors.
Outside amenities include a tennis court, free form gunite pool and pool house with two full baths, a kitchenette and changing rooms on the first floor and a guest suite above, and of course, the large floating deep water dock. Large enough to moor a yacht and steps from the backyard, no docks can now be built under current zoning restrictions.
A natural Artesian spring on the property, over time, created the lovely freshwater pond. Streams thread through the estate, tumbling over rocks and helping to support the lush gardens and vegetation. This serene outdoor space has been enhanced by walking trails, quaint bridges for water crossings, spillways to capture the sound of falling water and meditative sanctuaries scattered throughout. Some of the outdoor walls and features date back to the mid-1800s and the original estate.
Said Mr. Meier: “Rainbow Landing is a once-in-a-lifetime opportunity to own a waterfront estate within walking distance to the quaint village of Oyster Bay, with its restaurants and shopping.”
Oyster Bay is famous as the long-time home of Teddy Roosevelt, 26th president of the United States. His estate, Sagamore Hill, is now the Sagamore Hill National Historic Site, which includes the Theodore Roosevelt Museum.
