Any photos of this long wall ? how long is it ? Most would treat it as a gallery style design.

its about 20 feet and is part of the living room our couch is directly facing it. This is a condo with the living room and dining room combined into one wide open space. We would like to put a TV there and need some storage, but any buffet we have seen looks dwarfed on the wall. I have thought of putting 2 of the same buffets together but even that looks dwarfed. I would like to make it one flowing wall instead of looking disjointed.
