Seats, fences, and other centers, placed in the landscape to connect the garden with the buildings, will form a continuity of structure between inside and outside.

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Positive space in gardens must be created by placing buildings to form positive outdoor spaces, then differentiating them with structures, then allowing natural life to animate further centers.claim0.816
  Operational sequence for creating positive garden space.
• To make each garden a center and each house a center, lots must be composed of two sub-centers (house area + garden area), producing irregular zig-zag lots — not simple rectangles as in conventional subdivisionsclaim0.805
  Alexander's claim that center-generating requirements force unconventional lot geometry.
• It is my belief that a garden is a structure — not very different from a building.claim0.801
  Foundational claim that gardens are built artifacts, not merely natural growth.
• This living structure in a garden is very different from the kind of structure typically created by 20th-century landscape design or landscape architecture.claim0.796
  Contrastive claim distinguishing the result of living process from conventional practice.
• The structure of living centers appears in natural things — snowdrops, waves, clouds, mountains, foxes, grains of sand — and these too resemble the human self, requiring that there be a deep connection under the surface.claim0.793
  Alexander's argument that self-likeness in natural forms cannot be explained by artistic intention alone, requiring Proposition 2 for theoretical coherence.
• That is the essence of all gardens, and all agriculture: that built materials, human-made structures create a setting in which people, animals and plants can thrive.claim0.789
  Definitional claim about gardens as a symbiosis of built structure and living nature.
• If the fundamental process is working, a garden becomes a trace of the history of the land.claim0.786
  Key causal claim: unfolding process produces a legible history in the garden's form.
• The centers which bring life to a room are larger features which lie beyond the boundary of the room.claim0.780
  A key insight about position and context.
