A fairly large, cold room, the potions classroom is located in the center of the dungeons. Walls are lined with shelves containing all sorts of bottled ingredients, and there is a student supply cupboard as well. One corner of the classroom holds a basin where water pours from a gargoyle's mouth.

The office is reminiscent of the professor himself. An elaborate room filled with trinkets, old artifacts from past students and aquaintanceships, and pictures of said people. There is also a small pantry space off to the side where more unusual and dangerous potion ingredients are stored.

Echoing the dank atmosphere of the dungeon, while having high-backed chairs and ornate decorations makes this the perfect dwelling for this cunning house. The walls are a rough stone and green lights hover overhead, a consiquence of the room being located under the lake.

This room is large enough to rival the space of the Great Hall. Brass pots and pans are stacked high, lining its walls. Over one-hundred house elves staff the kithens, levetating food through the celing and onto plates at meal times.
