Similar to the houses of Benthall Brooks Row, the Pass House is a two-and-one-half-story brick Greek Revival town house raised on a high basement with a side-passage plan. The corner house has two Doric porticoes on the first level: one on the left side of the Crawford Street elevation and one in the center of the London Street elevation. The staircase is visible just a few inches behind the sashes of the left windows on the London Street side. “Pass” is not a former occupant's name—the original owner was James Murdough, an attorney—but a nickname from the Civil War, when the house was occupied by the federal adjutant general's office and residents were required to secure passes for movement in and out of the city.
