The subframe is 2×4’s sitting on top of 2×8’s. The 2×4’s are cantilevered 15 inches over the 2×8’s on the front and 2 sides.
I built the subframes in my shop downstairs and had to disassemble them and rebuild them in my bedroom.
I screwed down 1/2″ osb plywood on the 2×4 subframe.
I ripped down 3/4″ walnut to 8 inches for the side frame.
Just mitered two 4″ pieces and put an “L” cap on those.
I wanted a floating look to it but the shadow from the ceiling light didn’t give it the effect I was looking for.
Bought some cheap rope lighting and mounted them under the 2×4 subframe. It added to the floating effect I was wanting.
With the ceiling light off and the rope lights on. Thanks for looking
