I have a copy of an original floorplan for the Tendo home in Ranma 1/2. Interesting enough Kasumi's bedroom is right across the hall from Ranma and Genma's room. Its been invaluable in planning out scenes in my Ranma 1/2 fan fiction as well as planning out battles in the Tendo home.
Anyway, I am looking for floorplans for other Anime locations if they exist.
* Furinken High School (Ranma 1/2)
* The Morrisato Residence (Ah! My Goddess)
* The Masaki Home (Tenchi Muyo Ryu-Ohki)
* The Kuno Estate (Ranma 1/2)
* NERV Headquarters & Terminal Dogma (Neon Genesis Evangelion)
Also, I'm trying to find floorplans for the Macross and for the Nadesco also.
