Kim Kardashian & Kanye West Have A Mega Crib

Once Kim Kardashian and Kanye West settle into their renovated Hidden Hills home ... they'll never have to leave, not even for a haircut or a movie.

The couple is a few months out from moving into their 5-acre compound. The unfinished business ... a last-minute decision to expand the master suite ... and clearly some major landscaping.

We're told the home will have a 2-story playroom, gigantic gym, basketball court, hair salon, full spa with facial and massage room, and a music studio for Kanye. There's even a FULL-SIZE movie theater with a Dolby sound system.
