1. Perform a study on the Oak Cottage to document the structure's history and condition. 

2. Determine a defined timeframe (3 years or less) for a third-party partner to identify a purpose and a means to utilize and maintain the existing Oak Cottage. If a third-party partner does not establish a viable mission-alligned plan for use and maintenance within the defined timeframe, then remove the structure and restore the landscape to open space.

Nestled on the East Branch of the DuPage River in Naperville, Illinois, sits the Greene family homestead with a 14,000-square-foot barn, the largest one in DuPage County, and a farmhouse lovingly called Oak Cottage by the family. One of the county’s earliest settlers, William Briggs Greene, acquired land in 1843 and developed the farmstead. Home to six generations of the Greene family, the homestead serves as a tribute to the courage and determination of the early settlers, who came in lumber wagons to the dense rolling prairie woodlands and learned how to farm and manage livestock. This book is also the story of William Bertram Greene, a father, grandfather, businessman, and philanthropist, who with his remarkable wisdom and foresight secured the preservation of the Greene homestead for future generations by donating it to the Forest Preserve District of DuPage County in 1971.

Greene (1886-1982) donated ten acres of the family’s homestead property to the Foundation.  The proceeds from the sale of the property to the Forest Preserve District of DuPage County were placed in a designated fund the following year to ensure the perpetual guardianship of the Greene Homestead.

Ideas! Energy! Resources!

Three of Stantec's second draft ideas are supported by previous volunteer efforts addressing adaptive re-use.

Review 2019 recommendations of the Greene Barn Ad Hoc Committee and integrate those potential community uses with opportunities that include a more intimate Oak Cottage venue for book groups, senior drop-in, trail rest, small group meetings, weddings, lectures, exhibits, board games, knitting together, high tea, folk concerts, scout visits, storytelling.

Oak Cottage

W.B (William Bertram) Greene, below center, embraced the hearts of his family and community by securing the family homestead in the care of the Forest Preserve District of DuPage County. He envisioned future generations of all peoples welcome to the land and home and barn; empowering lessons of culture and nature. 

In the 1970s the Naperville Heritage Society recognized the significance of Greene's generosity with a commemorative plaque. It is hoped that Oak Cottage will one day be open to the public in adaptive reuse.

Greene Farmstead

Oak Cottage & Greene Barn

In 1850, the central portion of Oak Cottage was built by William Briggs Greene. It grew wing by wing through the years sheltering six generations. Simple lines define the exterior. The fireplace and mantel are slightly carved Vermont marble. At one time 16 people lived under its roof. 

Buildings were added as the farm grew and prospered. The 14,000-square-foot barn began rising in the 1870s. The Greene Barn built from locally quarried limestone and hand-hewn timbers sheltered animals, hay, grain and tools.

Oak Cottage, the barn and 10-acre homestead were donated to the District by William Bertram Greene, grandson of William Briggs Greene.

Honoring Our Built Heritage

Historic preservation is a celebration of community. It maintains a record Naperville’s history and culture by keeping buildings alive through adaptive reuse. It helps define our identity, keeps our community intact, and is part of a healthy community.

We believe that preservation pays. Historic preservation is good for our local economy:

  • old buildings attract new businesses
  • old buildings attract people

Historic Preservation is environmentally friendly. The greenest building is the one that is already built.
