Located along Main Street on the city's eastern side,[1] it is a distinctive landmark and has been named a historic site.

With the community's rapid expansion, Watt sold more land; by 1820, only 148 acres (60 ha) remained in his ownership.

Using the money from the land sales, Watt built a new farmhouse in 1826;[2] two stories high, it is a brick structure with a stone foundation and a metal roof.

Becoming a leading local businessman, he made an extensive addition to the house in 1852; this new structure took the form of an I-house.

A smaller addition, built in 1885, is a frame structure attached to the original portion of the house.
