When the Masonic Lodge in downtown San Luis Obispo needed to replace a failing 156-year-old skylight, they trusted us to deliver a solution that was both structurally sound and historically respectful.

Our team handcrafted a new steel skylight with the same iconic geometry: six rectangular base sections converging into a circular apex—an elegant hexagonal form perched atop this 4-story landmark built in 1870. At over 1,200 pounds, the new unit was precision-lifted into place by crane, one story at a time.

This wasn’t just about replacing a skylight—it was about preserving the integrity of a space that has seen generations pass through its halls. At AIW, we’re not limited to windows and doors. We bring the same attention to design, engineering, and detail to complex architectural steel and glass assemblies, whether for a historic preservation, a custom wine cellar, or a one-of-a-kind skylight.
