The Ellas-McKay House is a historic house at 404 North Wells Street in Clarendon, Arkansas. It is a two-story wood-frame structure, with a hip roof and the irregular and asymmetrical massing typical of the Queen Anne period. The left side of the front facade has a clipped-gable projection, while the right side has a semi-circular porch with an engaged gable dormer above. Both of these gables have decorative barge-board. The house was built in 1908 by T. S. Ellas, a prominent local builder, for his own family. In 1948 it was acquired by R. J. McKay, a prominent local civic leader.[2]
