Lone Rock was a design concept developed in a response to a call for ideas to replace a proposed design that was not meeting the client's desire for an impactful architectural expression. In the client's words, the intent of this portion of the project was to present a view from the base of the valley on the site that caused visitors to say "Wow, what is that building up there!?" and to draw them to what would be the central building of the resort/retreat complex. 

 

It is intended to present the appearance of complexity, while in reality remaining technically quite simple. The main hall consisted of 16 bowstring trusses, all configured at the same angle, and each placed on a pair of columns. The pairs of columns vary in height, creating the illusion of a section of a torus, and drawing the viewer closer to try to understand the shape. Simple gabled roofs would be placed between each set of trusses, and the walls below would all rise vertically to meet the roof.

 

The concept was selected by the client out of several dozen proposals, and was developed further before the lead architect chose to pursue a different direction, and the concept remains unbuilt.
