5/4 Doors Click thumbnail to enlarge Simple flat-panel doors become striking with the use of 5/4 lumber. The 1” thick door has a dramatic recess with a stepped double bead molding detail. Interest is further added by combining cherry and walnut cabinetry and bumping out the sink cabinet, which features a stainless farm sink. Storage in this small kitchen is maximized through the use of corner drawers, a bi- fold lift system above the refrigerator, and additional storage on the back of the peninsula.
