[aephi alum]

My sorority was unhoused, but Panhel had a room in the student center that members of all sororities could use. AEPhi and Theta (the two unhoused sororities) stored our ritual stuff there, in locked trunks, and we could use the room for committee meetings. Panhel meetings were also held there. People could also hang out there and study as long as there wasn't a meeting going on. That was the closest thing we had to a chapter room.

To answer ktsnake's question - when my husband and I were house hunting, we saw a house with a hidden room in the basement. You opened up what looked like a closet door and there was a pretty big room behind it. Since it was in the basement, you couldn't see that the outside wall didn't match up with the inside wall.
