The interior features elaborate and extensive woodwork, quarter-sawn oak floors throughout the house, one of the longest cantilevered staircases on the East Coast of the United States, a large and ornate antique Eastlake-style chandelier in the dining room, and the only known existing installation of M.H.

On the morning of October 8, 2023 the house caught fire, resulting in the residents being displaced and a total loss of the historic interiors.

It became one of Olean's most important industries at that time, eventually growing to employ 50 skilled laborers with an output of 2000 wagons per year.

The foyer contains access to the main staircase with a large carved newel post made from cherry and Birds-Eye Maple.

The staircase and landings are cantilevered above the first floor and feature a continuous varnished maple railing supported by 102 turned spindles.

The second parlor, also known as the "drawing room" or "ladies salon" features white wallpaper depicting gnarled trees and fanciful scenes.

These images are how the house appeared at that time, and do not reflect more recent changes to the structure such as the remodeled kitchen surfaces and appliances and the painting of the main and rear staircases.
