More than a deal or two has been made in here.
Businessman Mark Cuban – worth an estimated $2.5 billion – prefers his home office with a basic desk and work chair to a huge conference room with lavish furnishings.
"That's not really my style," Cuban tells PEOPLE. "I want to be comfortable."
Comfort is a multi-tasker's must-have, says Cuban, 54. Along with appearing on ABC's Shark Tank and investing in those start-ups, running his AXS.tv network, directing NBA'S Dallas Mavericks as owner and juggling other investment opportunities, Cuban is also an involved dad to kids Alexis, 9, Alyssa, 6, and Jake, 3 with wife Tiffany, 40.
