I'm remodeling my kitchen. First major remodel. I have purchased 12" deep unfinished stock cabinets I would like to make the 30x30x12 wall cabinet that will be above the stove/oven be 15" from the wall so I can add crown molding to all the wall cabinet tops later on in phase 2 of the remodel. Is this possible by attaching 2x4's to the existing studs and attaching the cabinet to those?
