Teppei's House is the home and laboratory of the Saiseiya, Teppei. It is located in the Knocking Ground.
It is built high-up inside of an old dead tree within the Knocking Ground and a flight of stairs are carved around the tree which lead straight up into the adobe. Not much of the inside is seen, but it appears to hold a dining or work table and shelves full of all kinds of ingredients that have been revived by Teppei.
