Based on a 4 foot diamond grid, the Arnold house presents little of itself to the public side.  As he would do with many of his Usonian houses, Wright opens the house on the private side, facing away from the street.  

In 1959, after Wright's death, a third wing was added to the house by John Howe, chief draftsman at Taliesin and a long time Wright apprentice.  The original owner still occupies the house.
