In 1965, while not yet a licensed architect, he designed a house and studio for his parents in Amagansett, NY, that became famous and revolutionized beach house design. When he did take the professional licensing exam, he was surprised to see a multiple-choice question on the test that asked "Which of these is the organic house?" The choices included the house he designed for his parents. He wanted to answer that the organic house was his, but in order to pass the exam he chose Frank Lloyd Wright’s Fallingwater House. He knew that was the answer they wanted. He passed. By 1977, Gwathmey had designed 21 houses and renovations while still under 40 years old and ten years of practice.
