It's the kind of house that makes you feel as if the rest of the world doesn't exist. Maybe that's because of the mesmerizing view of the Hudson River, which draws you in as soon as you cross the threshold. Or perhaps it's the pale, utterly unadorned walls or the precisely placed furniture. Whatever the reason, there's something here that makes even the air seem cleaner, fresher, more limpid. You want to take a deep breath, reach for the sky and let all the stress within you evaporate.
