The house has three main floors, but is further divided by seven levels. The first floor is notable for the very large drawing room, containing a parlour piano manufactured in London, England in about 1820 and two oil paintings whose subjects are unknown. The first floor of the house also contains the formal dining room and a room that is currently interpreted as Isabella's bedroom (though this would likely have been a morning room for other families living at Bellevue in the 19th Century).
