My first question is what are you going to display ? These always seem like a good idea until people are back asking how to make them work. If you have lovely things that need display then go for it . If not do 30” high cabinets on either side with doors add a piece of art above one and the T.V above the other and you are done.Maybe something nice dispalyed on each one.I just find these cluttered shelves with dozends of little things just busy and dust collectors.Since this is from scratch for heavens sake do not put the T.V above the fireplace.
