A mezzanine floor containing the house pantry was located halfway up the staircase from the first floor to an upper floor where the private rooms were located. The chic dinner service and silverware was stored in this room, as were household effects that were not used on a daily basis, such as foot stoves, preserving jars, coal scuttles and copperware.

Pantries like this were the domain of the lady of the house, who was responsible for running the household. Louisa Willet-Holthuysen kept charge of the keys to the china cabinets containing the expensive porcelain, silverware and linen. Everything was counted before the room was relocked. And woe betide the responsible servant girl if something was found to be missing; she would be dismissed on the spot.
