With a sprawling terrace and a castle-like exterior, the home sits on a quarter-acre lot in the Kalorama neighborhood near Embassy Row in Washington, D.C. The 2011 remodel brought the total number of bathrooms to eight-and-a-half, along with three fireplaces and an "au pair suite," spread out over roughly 8,200 square feet, according to real estate data. It features parking for up to 10 cars. (Photos courtesy of Mark McFadden.) See the listing here.
