Architectural Record reported that San Francisco’s 833 Bryant was a chrome monolith when it was first constructed, a zigzagged structure with new CorTen steel and corrugated aluminium panelling, the six-story community housing project by David Baker Architects was a fresh addition to the block. Three months later, it looked completely different. The oxidized Corten exterior gained a rusted texture, contrasting with its once-matching aluminium panels for a gracefully aged façade. Architects David Baker had deliberately selected enduring materials that were durable, cost-efficient, and enhanced the project’s beauty over time. Designed in partnership between Mercy Housing, Tipping Point Community, and the San Francisco Accelerator Fund, David Baker Architects combined unique design techniques and sustainable, low-maintenance materials to create a quality shelter for the Department of Homelessness & Supportive Housing of the City of San Francisco.To achieve 833 Bryant’s time-worn façade, David Baker Architects tapped the experts at BŌK Modern, a metals innovator with weathering steel offerings. Backed by a qualified team of architects and engineers, BŌK Modern had the unparalleled capability to support David Baker Architects’ ambitious goal to cover large modular units with hundreds of CorTen steel and aluminium panels. BŌK worked collaboratively with David Baker Architects through unforeseen challenges to create an enduring, timeless structure with little upkeep required.In order to maximize efficiency and philanthropic funds, David Baker Architects designed modular units off-site while 833 Bryant’s foundations were poured and utilities were installed on-site. The completed modular units were then situated by a crane, which required precise alignment. In places where the alignment was off, the versatile façade offered the aesthetic coverage needed.Using 3D scans of the entire building, BIM modelling was used to locate the offsets and customize the Cur-Ten panels to fit. The final project was installed with only three remakes—a material-saving solution to an unprecedented challenge. Plus, the undulating panels seamlessly masked misaligned modules in a way that flat finish systems such as stucco could not. The sheet metal takes advantage of modern technology like CNC laser cutting and forming to create exact cuts with minimal waste.

The rice field-inspired perforated pattern adds an abstract focal point to the main façade of the building as well as areas of panels that cover HVAC unit grilles, delivering an uninterrupted continuity to the undulating façade.
