Walnut Slatted Sideboard: 72-Inch Three-Door Cabinet

A modern walnut sideboard woodworking project with three slatted doors, adjustable interior shelves and a recessed plinth base. At 72 inches wide, 18 inches deep and 30 inches high (1829 × 457 × 762 mm), this storage cabinet suits a dining room, living room or entryway.

The design combines a solid walnut case and top with 45 vertical door slats, 15 per door, and a 1/4-inch hardboard back. Framed inset doors and subtly eased edges give the cabinet a clean, architectural look. Three separate storage compartments each include an adjustable walnut shelf.
