# Half wall supporting 18" overhanging counter -- can this be done?

As part of an upcoming kitchen remodel we plan on knocking down a (non-load bearing) wall between the dining room and kitchen. We are thinking of converting a portion of the existing wall to a half wall and placing an overhanging quartz countertop on it to create a peninsula. See attached Sketchup screenshot. This layout was suggested to us by a professional designer and my question is whether it makes sense structurally. Normally there would be a row of cabinets on the other side of the half wall, and the total amount of overhang would be ~1/3rd the overall width of the slab. Unfortunately there is no room for this in our 1950's-era, 10'x10' kitchen so the entire piece would need to be supported by the 4" half wall. I could perhaps see this working with enough reinforcing but I wanted to see whether anyone else has attempted such a feat and what the outcome was.

• Are you opposed to having corbels underneath the countertop providing support? And what is the thickness of the quartz? Commented Aug 16, 2018 at 14:41
• Not opposed to corbels, but invisible braces would be preferable (though probably unrealistic here.) standard 3cm countertops.

• There are pretty thin metal corbels that can be used, both in L shape and as flat bars that are attached to cutouts in the knee wall. You'd need to verify with the counter installer if that would be compatible with the countertop.

• Corbels only solve the secondary problem. The primary torsional force is at the floor joint. The wall would need to be securely fastened to the floor framing at multiple points. Commented Aug 16, 2018 at 22:03
• I did something similar by firmly mounting the subcounter mdf then embedding steel diy.stackexchange.com/questions/20862/… Commented Aug 17, 2018 at 6:52
