Built c. 1826 and c. 1831, the two houses are statewide rare examples of a transitional Federal-Greek Revival style executed in brick.

The two houses each stand with a gable facing the street, and additions extending northward, toward the Saxtons River.

They were built for Peter Dean and Lucius Alexander, co-owners of a textile mill that stood on the river bank north of Milldean (the left house of the pair).

Both originally presented an early example of the Greek Revival side-hall plan, executed with predominantly Federal details.

It has a three-bay facade, with the entrance in the rightmost bay (as that of the other house would originally have been set), with identical styling.
