Mission Statement

CARING- Reducing our ecological footprint – this value underlies decisions about incorporating active and passive solar power into the homes, a system which recycles our waste water for reuse as flush water, growing our own food, vigorous recycling. We are continually seeking ways to live more lightly on the land.
PARING-We are committed to keeping the interests of the land foremost in all our decisions. This is why we are clustering the homes on six acres, siting the community on the steeper portions of the property that is less suitable for gardening, are working with the natural contours of the land in laying out the community, and giving much thought to where to site gardens and activities.
SHARING-An ethic of finding ways to community as it naturally arises from living lives that consciously intersect with the lives of others.

Community Description

Hundredfold Farm is a 14-household rural cohousing community in the Gettysburg, Pennsylvania, area. The members of this multi-generational community are learning together as they explore the art of living in a sustainable way. The cohousing model is characterized by private dwellings, clustered housing, pedestrian-friendly design, and extensive common facilities. We promote sustainability with organic community gardens, active and passive solar components in our energy efficient homes and an innovative wastewater treatment facility that recycles water to our homes.
Some goals of Hundredfold Farm:
• To function together in a rich, supportive manner so that everyone will flourish.
• To provide an alternative to the loneliness that pervades our individualistic society.
• To own and manage the common land jointly, while owning our own private homes.
• To cluster the homes in order to reduce the impact on open space and agricultural land.
• To produce a significant amount of our own wholesome and healthy food using sustainable practices.
• To be a community of tolerance, open to everyone regardless of age, income, ethnicity, sexuality, or family situation.
