Deformscape is an outdoor extension to a private dwelling in San Francisco. Situated in a tightly packed urban neighborhood, this limited space outdoor sculpture garden inherits a large tree, and uses this sole arboreal presence to establish a gravitational pattern of grooves that are focused towards the tree's centroid. This asserts the valued presence of the carbon-absorbing tree and its green canopy overhead, while allowing for a maximum of usable surface area below free of other vegetation. To generate the resultant pattern, a 3-dimensional bulge is formed around the tree, and its distorted wire-grid projected onto a 2-dimensional surface. Taking into account appearance effects created by perspective views from inside, the resultant planar surface appears sink around the tree.
