BACKGROUND:
Remodeling our kitchen and SWMBO wants open shelving on one wall versus piecing together 10' of upper cabinets. The lower cabinets on this wall will actually have a big 33" sink and lots of countertop space on each side. The shelves would hold all our dishes, cups, some pots, some pans, and decorative things. I really like floating shelves so am hoping to build the frames out of 2x4's that screw directly in to the wall studs. Something like these (only finished completly):
QUESTION:
My question is if two of my shelves cover the entire 10' width of the wall from end to end, is this shelving system strong enough by itself without any additional support brackets? Here is more or less the layout we are going for:
