The Houston Zoo’s Reptile and Amphibian building was built in 1960. It replaced the original Bird and Reptile House, which was a wooden structure on the site now occupied by the Fisher Bird Gardens. The building was designed by Irving Klein and Associates and was built by Brown Construction Company. The Reptile and Amphibian building was built through a bond issue passed in the mid-1950’s, and was the first “modern building” in the Zoo; other facilities built on this bond issue were the Small Mammal House, the Tropical Bird House, and the Sea Lion Pool (which was the first facility constructed). Irving Klein also designed the Sea Lion Pool and the Small Mammal House.
