An eight-car garage, bricks imported from England, 20,000 square feet of interior space, 50 acres of exterior space, seven bedrooms, seven fireplaces and an art gallery are among the features in some of the properties on the market in the Washington area.

The properties range from a 10,000-square-foot, 20-year-old house in McLean going for $5.6 million to a European-style villa in Potomac selling for $14 million:
