Basically, the Plantation desk is a Fall front desk with a deeper stand or bottom part. The extra space or ledge of the bottom part of the desk serves as a support for the fall front, thus eliminating the need for retractable supports . Like a normal fall front desk the work surface must be cleared of all materials in order to raise it in a vertical position and thus close off the small drawers and pigeonholes set in front of the user.
While the fall front desk evolved from placing a chest, on its side, on a stand made for it, to its exact dimensions, as is the case with the Bargueno desk, the plantation desk form was born by placing such a chest, on its side, on a table a bit too deep for it. The fall front usually settles at a slight angle once it is open, in order to give a slanted work surface to the user
Some plantation desks have two panel doors instead of a fall front and the ledge is hence much deeper since it serves as the main desktop surface
