"The Great Houses of Gallifrey were the sentient homes of the Time Lords. They were sometimes confused with Chapterhouses."

Looks like they're being confused even on this wiki, since all of the houses listed on the Great Houses page are in Category:Gallifreyan Chapterhouses, while Chapterhouse states that Chapterhouses are the same as Chapters, which are listed in Category:Gallifreyan Chapters.

So, which are which?
