John sought out his father's former employer, Louis Sullivan, and had a series of conversations which inspired him to practice architecture again. The next year, he and his family moved to Long Beach, Indiana, so that he could establish his own, independent practice. Wright also opened a second office in the Warren Building in nearby Michigan City. His second child, John Lloyd Wright, Jr., was born in 1925. During this time John's designs began to shift from his father's Prairie School style to the emerging International Style. This transition was particularly notable following a 1929 trip to Europe. Among the houses he designed were the Hoover-Timme House (1929), John and Isabel Burnham House (1934), Lowell E. and Paula G. Jackson House (1938), and George and Adele Jaworowski House (1945-1946), all listed on the National Register of Historic Places in 2013.
