Built between 1902 and 1905, the Martin House is distinguished from Wright's other prairie style houses by its unusually large size and open plan. On the ground floor an entry hall bisects the house. To the right, behind a large double sided hearth, is a central living room. The room is flanked by a dining room and library which together create a long continuous space. The other axis, centered on the hearth, continues the living room out to a large covered veranda. To the left of the entry hall, is a reception room similar in size to the living room, the kitchen, and several smaller rooms. A separate mass provides for a reception room hearth, and one to the level above. The wing completes with a porte-cochère balancing the veranda. Above the entry hall, stairs wrap a small covered light well opening to the second floor. This floor provides eight bedrooms, four bathrooms, and a sewing room. The entry hall continues on axis to the pergola and conservatory beyond.
