As his son, John Lloyd Wright, says, McArthur continued his education in Austria and Italy, opening an architectural firm in Chicago with partner Arthur S. Coffin in 1912.
[5] His brothers, Charles and Warren, Jr., commissioned Albert McArthur to design a resort hotel for them in Phoenix, which is the Arizona Biltmore.
The system was an ideal choice for material that could be produced on site, especially in the desert of Arizona.
McArthur modified the square blocks and made them rectangles, much to Wright's dismay.
Wright's presence in Phoenix during construction gave rise to the notion that the hotel was his design and not McArthur's.
