It might be cool to have some nice flooring instead of raw concrete and a wall or two finshed off for putting up posters and memorabilia.
Equip it with a wall mounted vacuum with a long hose, cabinets and counters for tools, exhaust fan, overhead lights as well as a retractable droplight, 100 amp service or more if welding will be done, a 'frige for the beer, and hot and cold running maids.
