The mansion is one of the best preserved Italianate Villa homes in the United States, with original Victorian furnishings and finishes.

[5] The architect was Samuel Sloan of Philadelphia who also designed the Southern Mansion Hotel in Cape May, New Jersey, and Longwood in Natchez, Mississippi.

[4] The house bears a strong resemblance to a design published by Sloan in his 1852 Model Architect, in which he promoted the Italian Villa style.

The mansion is embellished with marble fireplaces and gilded mirrors, mostly added for the Packers' Golden Wedding Anniversary on January 23, 1878.

[6] The mansion is also filled with many distinct details including Gothic gingerbread trefoil motifs and window arches, and exquisitely carved panelling.

Ronald J Sheehan serves as executive director of the Mansion Museum as is in charge of overall administration of the National Historic Landmark property.
