If you could build a dungeon-You have every resource alavaible
How many rooms-
Location-in the world-
Special Features-
Why you needed to build the dungeon-
rooms; to many to count easisly; big yet subtle
rocky mnts
big; deep; with every terrain known to man; funner than a amusment park, more deadly than a pit viper
uhm, to keep out the government, crazies, aliens, grungers, crystal bearing musicians, and anyone else I label unsavory like anyone who likes disco.

Why you needed to build the dungeon-
Think large, huge even, like Mall of America Big, or all of the rooms in a large Las Vegas resort. It would be located in a deep trench in the Pacific with a land entrance. The larger portain would be a crazy madhouse of oddities where physical talents are needed to get to safehavens and in the end my sanctum filled with arcade games, a lap pool, an all you can eat buffet, and other cool things. I would invite celebrities and politicians as well as random people and friends/family to come by and see who can navigate through quickest to get to me. Then i would make a reality show about it...

Loads of secret doors. Tiny little rooms, that force the PCs to do melee. Maybe some lone beholders who dont care who they hit. And loads o' traps.
'Dormant' volcanoe(note, put some fire critters in those rooms).
I'm gonna put in an evil dragon or something...Ooh! here it is: Red dragon(villain). On a narrow bridge that needs a balance check. Lava under the bridge.
Ouch.
To keep them pesky knights away.
