The "Beach House" is the home of the Steven Universe and serves as the entance to the Crystal Temple.

About
The Beach House is linked together with the Gems' Crystal Temple, where the Gems can access their own rooms, while Steven stays in the interior of the Beach House. The Beach House is also the housing for its only Warp Pad leading to various on Earth locations.

Trivia

 * As revealed in "Lion 3: Straight to Video", the entire Beach House was only built onto the Crystal Temple after Rose was well into her pregnancy with Steven.
 * This probably means the Beach House is probably as old as Steven himself is, if not slightly younger.
