Light as a
Building Material

We treat light as a fundamental layer of interior architecture. Our specification process involves rigorous testing of beam spreads, center beam candle power (CBCP), and aperture finishes to ensure the light disappears into the architecture.

"The quality of the light is as important as the quality of the millwork. We specify for longevity and atmospheric impact."
