I feel like I have seen every room of this area but I just can't find any ladders or stairs that let me up to the second floor. Is it unlocked later in the game?

That area is unlocked later on in the game. One of the Bloodborne wiki outlines the exact criteria:
To get to the Lecture Room 2nd floor, you must first beat the One Reborn, and proceed past him through Advent Plaza, where you will inspect a mummy that teleports you to the 2nd floor lamp of the Lecture Building.
