Additional rooms are created by a rear extension that was formed by walling up a large two-story veranda.

Pilasters with Ionic capitals separate the second-story windows, while no comparable ornament is present below.

A shallow hip roof covers the building, pierced by chimneys on either side, while its overhang permits room for a cornice composed of large bracket.

It was built for English immigrant Thomas Clegg, a small-scale industrialist who owned Dayton's first iron and brass foundries, although the precise date is uncertain; a stone building was constructed on the present house's site in 1831, and while this may be the present house,[2] it might not have been constructed until the following year.

[2] While the original design was clearly Greek Revival in style, renovations in the middle of the nineteenth century included modifications to the cornice and other changes that together produced an appearance typical of the Victorian era.
