Dr. Dre's Los Angeles mansion already features an infinity pool with ocean views, a gym, outdoor kitchen and a moat, but according to documents obtained by TMZ, the producer is looking to expand his home. A May 29 report claims Dre is looking to add an underground section to the mansion.

Documents state the legendary producer has plans to dig up a portion of his property, which is roughly the size of his current home, to build a basement that will also include lightwells. Dre has obtained permits which will allow him to add retaining walls around the house, as well as a guard house.

While a price for the job is unclear, excavation and addition costs, along with construction could reach millions of dollars. The Compton artist applied for the permit a few years ago, but was only recently granted them in May.

Although the producer caught a win with the permits for his planned expansion, he recently lost a trademark battle against a Pennsylvania-based gynecologist named Dr. Drai. Dre tried to block the medical doctor from filing a trademark for the name, claiming it would cause confusion between the two.

Ultimately, the trademark office sided with the OB-GYN, who has also written books under the name, and stated there wasn't enough evidence to show that the public would be confused by the names.

Head to TMZ to check out pictures of Dre's mansion before its expansion.
