The Darwin Martin Complex consists of five interconnected buildings designed as a unified composition, including the main Martin House with a pergola that connects it to a conservatory and carriage house with chauffeur�s quarters and stables, the Barton House, a smaller residence for Martin�s sister and brother-in-law, and a gardener�s cottage (added in 1909).  It is considered one of Frank Lloyd Wright's penultimate Prairie style designs and one of his master works.  Darwin Martin was introduced to Mr. Wright by his brother William for whom Wright designed the William Martin House in Oak Park, Illinois. The property also contains the Greatbatch Pavilion visitor welcome and interpretive center.
