ARCHITECT's Ayda Ayoubi reports that in McLean, Va., overlooking the Potomac River, is the six bedroom, six bathroom Falls residence, a three-story, single-family house, built in 1999.

Featuring interiors by Washington, D.C.–based designer Thomas Pheasant and custom furniture, the 48,900-square-foot residence is now up for sale for $62.95 million, making it the most expensive piece of property in the Washington D.C. area. The residence includes a gate house with staff quarters, a 30-car parking garage, a wine cellar, a full-size tennis court, an infinity pool, and an outdoor terrace that offers panoramic views of the Great Falls. But, that's not all. The $62.95 million price tag will also get you a 2,764-square-foot, 1950s house designed by Frank Lloyd Wright.

Named after late National Geographic photographer and writer Luis Marden and his wife Ethel, who commissioned Wright to design the residence in 1952, the Marden House is one of the three properties the architect designed in the Washington metropolitan area. Set into a rocky hillside, the almond-shaped, Usonian structure features 80 feet of floor-to-ceiling windows and is offered with some of the original, Wright-designed built-in furniture.
