Rob Kardashian can have all the sleepovers and home workouts he wants with Blac Chyna now -- he just got his own house, but his sisters are still within shouting distance.
TMZ has learned Rob bought a 4,256 sq. ft crib in Calabasas within the gated Oaks neighborhood. Our sources tell us he scored the 4 bedroom pad for $2.285 million. Kris Jenner helped out with the purchase, which is under the family trust, and it closed a week ago.
The Kardashians have quite the compound going -- Rob, Khloe, Kourtney, Kylie and even Lamar ... all live within a few blocks of each other. Mom and Kim are up the road in pricier Hidden Hills homes.
