Permeable boundaries between areas for lounging, dining and drinking are delineated by large-scale relief panels and vertical batten screens, which echo the architectural language of the space. In the bar area, a black granite counter anchors the space and provides a focal point for guests seated on striped banquettes, boucle armchairs or tufted leather loungers—all of which are grouped in various combinations.

The adjacent dining area features checkerboard-upholstered chairs that play off the black, gray, and white floor tiles laid in a geometric pattern. Custom cafe tables with beveled oak tops and maple-toned leather banquettes balance the grayscale elements, while Brightliner Sloane Armchairs—a previous collaborative design by Stellar Works and AvroKO that became a permanent collection—enhance the overall palette.

The Third Floor’s roof terrace also nods to Portman, with colours and prints across the soft furnishings lifted from a photo of the architect on a San Francisco doorstep in the 1970s. The custom banquettes surround a row of fire pits that are perfect for huddling around on a chilly evening. Both outside and in, The Third Floor provides multiple modernist-influenced spaces for visitors and San Franciscans to drink, dine and unwind.
