Oak Lea is a private home of 19th-century origin in the Layhill community of Montgomery County, Maryland, described as "the gracious culmination of architectural and building efforts dating back well over a hundred years." The house is composed of three adjoined blocks built at different times: A log smokehouse and a frame bank-barn with a stone foundation were originally located to the west of the house, dating from the property's original agricultural use. Additions of three log rooms were the only major changes made in the structure until the house was renovated in 1940.
