Mark Wahlberg -- Mine Is Twice As Big As Tom Brady's!

Mark Wahlberg's massive home in Beverly Park, CA is finally complete ... 30,000 square feet strong ... and it's twice as big as Tom Brady's house!

Wahlberg bought the six-acre property five years ago and had the house designed by architect to the stars Richard Landry, who also did Tom and Gisele's.

The home has a lot, including a library, wine cellar and a wood-paneled home theater, a rock formation pool with two jacuzzis, a slide, and get this ... a diving board!

And if you feel like playing sports ... there's a putting green and a basketball court.

The only thing this house doesn't have ... a talking teddy bear.
