I like how the wood floor runs in different directions on the floor. It makes the hallway feel bigger and definitely more interesting. Your eye doesn't know where to look, which makes the floor gain more attention.
If our concrete floor cracks, we're doing this to it! It's concrete with liquid gold to fill the cracks! (What the crap who thinks "hmmmm concrete cracked. I'll fill it in with gold!" What even kinda Scrooge mcduck lunatic is this?
