Laurelton Hall was Tiffany's architectural masterpiece. Situated on a bluff at Cold Spring Harbor, overlooking Long Island Sound, the eighty-four-room, eight-level building was surrounded by gardens of every sort. The entrance loggia epitomizes Tiffany's artistic mission in its combination of decorative art and architecture. It derives directly from the eastern façade of a palace in a red sandstone fort in Agra, in India. Tiffany's version incorporated glass and pottery in its fanciful floral capitals composed of glass and pottery. In themselves they are a testament to Tiffany's lifelong quest for beauty in nature. Each botanically correct flower—from left, the lotus, the dahlia, the poppy, and the saucer magnolia—is depicted in three stages of growth, from the bud at the bottom, just below the flower in full bloom, to the seed pod, at the very top. The glass-mosaic panels in the spandrels and the iridescent blue glass-tile frieze evoke Byzantine mosaics. The novel and fantastic quality of the totality bears witness to Tiffany's original artistic sensibility.
