Kanye West just got official approval to start building a new monster of a home on his ranch in Wyoming (the lakeside one) -- and by the sound of it, he's got a lot of work to do. TMZ obtained the building and zone permits Ye and co. filed in Cody, Wyoming, which were just signed off on over the past couple months. According to his plans, the guy's got a 10-bedroom mansion in mind ... and then some.
