The second Villa Wagner was built near Villa I, but the difference in design is striking. Otto Wagner's ideas about architecture had morphed from the Classical design of his training, expressed in Villa I, into a more modern, symmetrical simplicity displayed in the smaller Villa II. Ornamented as only a master of Art Nouveau could do, the second Villa Wagner pulls its design from Otto Wagner's masterpiece being built at the same time, the Austrian Postal Savings Bank.
