2. Strive for Wholeness
Form Consensus around an Articulated Vision
In General, Avoid Compartmentalization
Wholeness vs. Parts
Holistic vs. Analytical Mode of Consciousness
Buck the Trend
Develop a Pattern Language
Understand the “Land Ethic”
Read the Site
Listen to Stories
Obtain High Quality Feedback
Clearly Written Patterns = Quality Feedback

Local Materials
Issue Statement
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.
L
Solution Statement
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.
