this quote comes after a story of how three different houses individually unfolded in a shared place in nature where three families wanted to create a shared experience:
“The uniqueness of the houses, the sensation that they are like nature, different leaves off the same tree, comes in large part from the way these houses were later built.
All three houses used a common form of construction. All have stem walls of stone, heavy stud walls, open ceiling beams … stones in the courtyards, wooden windows …
One might make the mistake of thinking that if each house had its own unique system of construction … But this is not the way it works.
Imagine an oak tree on which there was a fig leaf, a hazel nut leaf, a willow leaf interspersed among he oak leaves. This would not create a feeling of uniqueness in the different leaves. It would merely be bizarre and chaotic. The quality of uniqueness is a quality of particularity which stems only from necessity … It is because we all have noses – essentially similar in shape and structure 0 that we recognize a certain person’s nose, mouth, eyes. This sameness provides the ground against which we see their uniqueness.
And just so with these houses. They are more particular, more unique, because they are all made within the same process of formation and construction – and the differences that come from place, person and temperament are made more visible, stand out, are there to be loved – because they ‘beat’ against the shared sameness.“
