This historic home has been called the Casa Grande, Hacienda, Rancho, and the Big House. It is the main house of the site and is certainly the oldest structure on the property. While there is some contention as to whether this is the home that Sebastian Martin built when he first claimed his land grant, we think that it is incredibly likely this is that home. As it currently stands the house has eleven rooms: a kitchen, a bathroom, library, dining room, grand parlor, and 6 bedrooms. At one point in time the house had 24 rooms to accommodate Sebastian Martin, his wife, and their 10 children in addition to the servants who lived in the house at that time.

The exterior of the house dates to the mid-1800s and is done in a Greek Revival style. This was the time period when the second story was added. The interior of the house looks as it did when Mary Cabot Wheelwright owned the home in the 1920s.

"Hacienda" refers to large landed estates which includes the land and a large house on the property. As the property shrank it was more appropriately called a rancho.
