That salt box in the back corner is going to be a brand spanking new coal furnace which is forever "just delivered" and about to be set up.
Two other things in this picture are the small table which will probably end up in the butler's room.
It was an incredibly cheap, red thing which I sanded, painted with brown acrylic gloss just enough to let a bit of the red come through, and painted the drawer knobs black gloss. It has a simple yet not brand-new look to it, just perfect for below stairs.
