[1] The one-story, spraddle roof dogtrot house was built in 1842 by Ezra Plumb for Asa Johnston.

The residence was built for Asa Johnston, born in Bibb County, Georgia, on August 24, 1798.

He had arrived in Conecuh by 1818, the year the county was founded, making him one of the original pioneers.

The front facade is seven bays wide, with a central open breezeway and doors on either side, framed by two windows each.

The central breezeway features a barrel vaulted ceiling, the only example documented in Alabama.
