The main house is a 2+1⁄2-story stuccoed masonry building in the Italianate style.

Now consisting of 16 acres, the original estate comprised several hundred acres, consisting of outbuildings, barns, and, ultimately, three large summer homes built as wedding presents for three of his children.

The house was originally approximately 8,000 square feet and was built in the mid-nineteenth-century Gothic style then popular in the United States.

His son and daughter-in-law, Katherine and Samuel Sloan, Jr., inherited the estate in 1907 and began large scale changes and modifications.

The house itself was expanded by approximately 5,000 square feet and completely redesigned in the then more-popular Italianate style, largely eliminating all Gothic traces.
