85 Natoma Street
To create a unique identity, the form of the building follows a gentle arc as the exterior wall becomes the roof.
An urban infill project of 9 modern residential lofts, Steel Arc is composed of a metal skin, cement-board panels on flat walls, and generous areas of glass. The lofts are separated vertically by windowless streamlined metal that curves back on the upper two floors — giving the building a rounded silhouette. The minimalist industrial interiors highlight acid-stained concrete floors, custom poured concrete countertops, bamboo flooring, and floating steel stairs.

“The building so deftly infuses its street, and the outlying transitional neighborhood, with clarity and sophistication it hadn’t known before.”

“A metal-sheathed structure whose sweeping curves and irregular composition inject refinement into industrial aesthetics.”
Art-Sites, San Francisco 2003
“Say farewell to one of the region’s best residential buildings of the young century. Known informally as Steel Arc, it’s a modest joy of shiny steel with a rounded silhouette, nine modern units that always looked at home amid the workaday masonry neighbors.”

*In 2010, Steel Arc was taken under eminent domain for the Salesforce Transit Center.
