The House Today
The Ellwood House property today consists of about 8.5 acres, which includes the wooded area to the North of the mansion. The original Ellwood estate totaled more than 1,000 acres, extending north and west of its current boundaries. Much of the property was pasture and farm land devoted to the Ellwood stock farm "Ellwood Green" for the breeding of Percheron draft horses.

The Ellwood House has undergone two major transformations since the time of its original construction in 1879. As a result, there are three periods which need to be explained in order to understand the development of the house. Each of these periods can be related to both the exterior and the interior of the mansion.
