Architect Chris Downey is standing next to a pile of Sheetrock, balancing a white cane in the air like a tightrope walker’s pole. The week before, construction had begun on a new office for the Independent Living Resource Center of San Francisco, or ILRC, a nonprofit community center for people with disabilities. Downey holds the cane up to approximate for the center’s executive director, Jessie Lorenz, how the reception desk will jut out at an angle from a concrete column. Lorenz takes a step, and a pile of pipes on the floor clatters. “I don’t know what’s over there,” says Downey. Lorenz giggles. “I hope I didn’t break anything,” she says. Lorenz regains her footing and touches the cane. “That makes sense,” she says. “It’s almost like we’re funneling people into this part.”
Even though Lorenz, who, like Downey, is blind, can’t see the space before her, she knows exactly what to expect. On her desk at the ILRC’s current office on Mission Street, she keeps a tactile floor plan that Downey printed for her. The plan’s fine web of raised lines looks like an elaborate decorative pattern, suggesting a leaf of handmade stationery or a large sheet from which doilies are about to be cut.
