When the owner of a landmark home passed, J S D A Inc. was requested to evaluate the property. This home in Boise, Idaho was designed and constructed by Art Troutner, a remarkable designer and structural engineer in 1958. The Phillips Residence was a point of innovation of the wood and metal truss joist which Art Troutner holds patent, pre-dating the foundation of his company of the same name. The six-sided folded roof structure is like a piece of origami supported by minimal steel, and complete with a raked zen garden. J S D A Inc. initiated the path toward its National Register recognition.
