This is the first time the hint is given that all the castaways are living in individual huts, when the audience watches Mr. Howell go from a single dwelling hut, down to another hut where Gilligan & Skipper are sleeping. Several feet are between each dwelling. Although they are never heard to discuss this or seen them build them, they would have been built some time after #1.20; :St. Gilligan and the Dragon" & could have been built during #1.24; "The Return of Wrong Way Feldman."
