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.
