The Round Pen is a standard size – 62′ diameter – open riding arena that is used to train yearling horses in a simple environment without distraction. This project was a re-invention of this rural building typology, using computer-numerically-controlled (CNC) laser cutting and digital modeling to create a kit of parts that was built on site by skilled craftsmen using only scaffolding, minimal equipment, and hand tools. Precise truss layouts were generated, along with parts and assemblies directly fabricated from the digital model. A unique convergence of design, manufacturing, and craftsmanship resulted from this highly collaborative and interdependent effort.  Designed with Joe Mashburn for Lyle Lovett at his ranch near Houston.  AIA HOUSTON ARCHITECTURE DESIGN AWARD 2008
