Here are two super rare images of Seth's room that was featured in the pilot episode only. The pilot episode was filmed in a real house located in Malibu, on the same cul-de-sac as the two story exterior house we see in nearly every episode. Ironically this house was a one story.
After the pilot episode, Seth's room was rebuilt in Raleigh Studios located in Manhattan Beach, CA, along with the pool house, Cohens house, harbor school etc.. Sadly the house used in the pilot later burned down from the California fires in 2018 (to read all about that go here). You will notice that Seth's room in the pilot episode is decorated much different then the rest of the series. Many of the band posters were switched out with more indie type bands but the majority of the other accessories remained similar.
