The property includes original fireproof doors and vault-like rooms associated with the building’s historic storage function, along with remnants of the former Kellogg Rock Gardens.

The current conforming use is professional office. Its historic architectural elements and established office configuration distinguish the property from conventional commercial space, while the Three Rivers address places the building on Portage Ave in southwest Michigan.
