Can a garage be too big?

you guys are lucky, i have to use my grandfathers 24x 30 garage or pack rat room, hes got tools but keeps way too much crap. i like the garage majal very nice. i keep hunting on clist for an old free building that either needs tore down or just taken over so far all i find are ads with no phone numbers. its sad really, ill tear em down and build em back up idc just please give my own area where im not riffling thru old bolts and stabbing my self with old knives and **** all the time. id ove a nice 40x40 one big door in a small side door, and a nice 40 x14 car port for my macho and my 4 wheeler. i think that should work for me.
