How do i spawn my structures together as a random dungeon

So i want to do a dungeon that randomly generates of some structures that i made.

Made Structures are Entrance, Corridor1, Corridor2, Corridor3, Junction 1(2 Exits), Junction2 (1 Exit), Dead End, Trap Room and Treasure Room.

How do i setup that the Entrance spawns with randomly either 1-3 Corridors or Dead Ends and the Corridors either spawns a Junction, Trap or Treasure Room?

Oh yeah not to forget the Dungeon should not go further than 4 rooms in each direction.
