Working Prototype
Self Portrait as a Flower Vase, 1997
A silhouette profile acts as basis for this eventual 3 dimensional object. Somewhat of an optical illusion, this invention*uses "negative space" or opposite space to identify itself.  Although attributed to psychologist Edgar Rubin in 1915, similar images can be found in eighteenth century prints.
The "Single-pin" method of installing a tree-house's structural framework  to a host-tree was devised to hold the tree-house securely with minimal damage to the tree and to prevent structural damage to the house!
Traditional Method
Single-Pin Method
The single-pin system utilizes a single galvanized steel rod to which the main support beams "rest" within an oval-cut collar. In this "tree-friendly" design, the single-pin passes completely through the inert heartwood of the tree, with minimal effect to the Cambium layer.
The initial support beam installed                         A second support beam is added            A cross-beam is slotted into support beams
The completed rib-carriage "free-floats" within the trees and acts as the foundation for the decking -and eventually the treehouse. 
After the decking is laid, the treehouse is framed
and a staircase installed.
Roofing, siding, windows and doors are added.
Railings add the finishing touch!
This entire treehouse is supported by only 2 single-pins!
