A bit of background: our lab is kind of ancient. It’s also enormous; my advisor owns most of our hallway. The group was once very big (one of those 20-30 people powerhouses), but these days it’s fairly small (~6, plus a couple undergrads at any given time). However, we still have all the space from those massive days of yore, so a lot of the space is… well, let’s just say a lot of the lab space hasn’t been touched in a while. I mean, every room is still used, but there are definitely nooks and crannies that, if owned by a lab that had to be more economical with its space, wouldn’t remain as untouched as they are when I find them.
