Prepare to be stunned by this waterfront mansion that’s just hit the market within commuting distance of New York City. The 35-room Westchester estate, appropriately named “All View” by its original 19th-century owner, sits grandly atop a three-acre peninsula jutting out into the Long Island Sound. The grounds (conceived of by Central Park and Prospect Park designer Frederick Law Olmsted) do not disappoint; neither does the house, which is full of historic details but has also received modern — and a few whimsical — renovations. It now boasts 13 bedrooms, nine wood-burning fireplaces, three kitchens, and a new geothermal heat and air conditioning system. The best part? Every single room offers a view of the water.
