Big Sean shows of his newly renovated mansion Big Sean purchased Guns N’ Roses’ frontman Slash’s mansion. Bis Sean spent over $8 million on the purchase and major bank on the renovations. Architectural Digest got a sneak peek at the mansion as Big Sean hosted the tour. The 11,000 square feet mansion has 7 bedrooms, a Taj Mahal-inspired fireplace, high ceilings, an underground nightclub, and an over 13 seat movie theater. Sean said, “I didn’t really change the design of it. I got the exact same couches that he had in here before, but I just got new ones because I don’t know what the f*** he was doing down here.” What are the must-haves in your dream mansion?
