The building site on Moss Alley in San Francisco’s South of Market district did not offer abundant natural light opportunities, so the owners, architect and construction company worked together to create a warm and inviting interior space that used both available natural light as well as great interior lighting to bring the focus inward. To add both an edge and some excitement the ceiling was addressed as a key design element. Sections of the ceiling were exposed to show the inner workings of the structure of building. In other areas where they had a straight shot to the roof, they cut large air vent like skylights to bring in as much available light from above. They could have painted the ceilings white to reflect more light, but they went a different direction incorporating our A4 Sound panel in Amber and straying from a continuously flat ceiling added movement by creating different elevations to the substructure that added an undulating sensation to the visual. The result was a warm, inviting and architecturally exciting space.
