ALDO LEOPOLD LEGACY CENTER2. Strive for Wholeness

Form Consensus around an Articulated Vision

In General, Avoid CompartmentalizationWholeness vs. PartsHolistic vs. Analytical Mode of Consciousness Buck the Trend

Develop a Pattern LanguageUnderstand the “Land Ethic”Read the SiteListen to Stories

Obtain High Quality FeedbackClearly Written Patterns = Quality Feedback

Sustainable Patterns Interwoven



Solution StatementL

Modernity has assumed it is OK to use building materials from anywhere in the world. On the other hand, a wide use of

locally available materials has many benefits on multiple levels.

Promise to only utilize materials that are available within a 500-mile radius,

preferably those that are present on ALF land. Do not ship local materials out of

the area for fabrication or refinement, and strive to do as little processing as

possible. The acquisition process for local materials must be regenerative, i.e. the place where materials are removed must be better off after the acquisition

than before.
