Built in 1929, this 9,000-square-foot mansion has been renovated by real estate magnate R. Donahue Peebles. It sits on a hilltop near the Naval Observatory and has a terrace with a pond and fountain. Inside, the home has dark wood floors and white walls, giving it a clean, modern feel. With 112 windows, a sunroom with panoramic views, and a living-room nook with a large bay window, it’s also flooded with natural light. Other luxury touches include a wine cellar, gym, and his-and-her dressing rooms.
