This piece is constructed using the biscuit method -- the two outer boxes are assembled first and then those boxes are assembled with the center shelf and longitudinal stringers (not visible) providing structural strength.
The oak drawers shown at right are constructed using box joints at the corners with the dividers in dadoes as is the plywood bottom. The drawers are on full extension slides and hold approximately 30 DVDs each. The cabinet on the right has a single shelf.
The wall unit (shown below) is built to the wall. I reduced the depth of the center section eight inches and also widened the area for the television. I faced the columns and center shelf with red oak finished to match the existing facing and designed to disguise the difference in width top to bottom,
