[1] The original Eaton School building is a two-story brick structure with a 12-bay front facade that contains round-arch window frames and a hip roof, previously covered with asphalt shingles.

The center window frame on the second floor of the east elevation contains a metal door for accessing a steel fire escape.

[2] The building's Romanesque Revival architectural style was common in early 20th century school designs, but Eaton School is considered by the Mississippi Department of Archives and History (MDAH) to be a unique example of the architecture because the building has survived intact for more than 100 years.

[1] In 1949, a one-story, flat-roof, brick addition was constructed on the west end of the original building, under the direction of architects Hearon & McCleskey.

When it was assessed for National Register status during the first decade of the 21st century, deferred maintenance had resulted in a leaking roof.

But, during that 5-month interval, the building's interior had been exposed to winter rains which weakened the supporting beams on the second floor.
