I kind of like this staggered wood console. Open shelf for a sound bar. Thick metal plate down the center to hide cords. Uneven wood surface. Way too wide for my room but shouldn't be too hard to whip up a shorter version.
Principles of design: Balance: This could at first appear to be symmetrical, but when you look at all the elements, such as the drawers on the left & the ottomans on the right, it makes it broken up more so it's not in such tight symmetry. Harmony: The shelf above the t.v. is repetitive by having the books, but then the room gets more variety by adding in the plant by the t.v. and the yellow ottomans.
