23 Beautifully Textured Board-Formed Concrete Homes

In February of 2007, two San Francisco art and travel addicts purchased a 3,200-square- foot former Chinese laundry and tooth-powder factory with column-free interiors and a zigzagging sawtooth roof in lower Pacific Heights. They customized a pair of shipping containers to accommodate their collection and reflect their passions, and hired a local company to sandblast the interior to expose the board-formed concrete walls and replaced the carpeted floors with Georgia hickory pecan planks— the longest, knottiest boards they could find—to further lengthen the loft and make it look more like a warehouse.
