The designers left two of the garage's three bays mostly open, only partitioning off a rear loading dock with a sliding-steel panel and adding a lofted storage area above new restrooms and a small kitchen. They appointed the remaining space with easily reconfigurable furniture, including tasting counters and a set of steel-and-wood “rafts” that do double duty as seating areas and a stage. The movable elements allow the space to function as a tasting room during the day and accommodate any number of events in the evening; since its opening in 2011, Smith has hosted everything from burlesque shows to wedding receptions in the space.

Kundig left much of the interior's wear and tear as he found it—you won't find pictures of pastoral vineyards or stately chateaus. The brick walls still bear the occasional scribble of writing, and traces of white parking lines cross the concrete floors. Water stains from a roof that leaked for decades have left the wooden ceiling truss beautifully mottled. “It's a reference to the time it takes to make wine,” says Kundig of preserving the building's patina.

The only major intervention is the “armadillo,” a shoeboxlike volume with a prefab timber frame inserted into one-third of the garage. It encloses a conference room and an open-plan workspace for up to 10 employees of Smith's enterprise. “It's parked like a Trojan horse in one of the bays of the building,” says Kundig. The box gets its nickname from the 15 steel panels that cover its top and sides. The L-shaped plates slide on a set of tracks running along the floor of the box's long sides, and another running overheard through the center of the office ceiling. They open the workspace to the tasting room, blurring the line between front- and back-of-house. “The public sees what we do, and we see the public checking us out,” says Smith. The box is raised on a platform to accommodate electrical and data systems and lined with cork panels to provide some acoustical isolation—though with four 90-pound subwoofers mounted in the rafters, the default volume for the music in Smith's tasting room is loud.

The design team converted one of the garage's three street-side openings into an entry for the office. The other two hold glass garage doors with steel frames and sashes that open and close with one of Kundig's signature hand-cranked mechanical systems. When open, the doors cant dramatically over a fenced-in plot of sidewalk, which allows for sipping outdoors in warm months. It also brings the scene inside the space into Walla Walla's downtown. The storefront is on a side street, just across a creek from Main Street's commercial stretch, and Smith was determined to be noticed by pedestrians. He even suggested painting the entire exterior black, but Kundig talked him down. “He wanted people on Main Street to say, 'Woah, what's going on down there?' ” says the architect.

On a recent visit, the garage doors did the trick as a group of people walking by turned to watch Smith—clearly loving the physicality of the process—crank open part of the facade. The playful mechanism added tens of thousands of dollars to the cost of the job, but Smith says it was worth it for the attention that he gets. The project's combination of tough materials, street presence, and versatility has created a destination that holds its own with the personality of its owner. “Many of our clients have an urge to take risks,” says Kundig. “But Charles is a force of nature.”
