Inspired by the very first synagogues, Lake|Flato envisioned a light-filled limestone enclosure surrounding a communal tent-like space. The traditional square plan was used to bring the service to the congregant. Light permeates the sanctuary with an ethereal glow. The Texas sun is diffused through a sky-lit oculus in the center of a Star of David 40 feet above, while clerestories allow light to slide behind the cantilevered concrete balconies. This creates ever-changing patterns of light that wash over and animate the Sisterdale limestone walls.
