Even though it is just across the Golden Gate Bridge from San Francisco, half of the land in Marin County is agricultural.  Exterior materials for the project, like Corten steel and simple board and batten siding were chosen to relate to local dairy barns.  The interior was designed as an open and flexible space to blur the distinctions between the café seating and retail functions, true to Pump’s original filling station pop-up.  More material was removed than added to develop the interior, out of a need to be budget-conscious but also to relate to the café’s basic and direct origins.  Existing roof framing and plywood is exposed for the ceiling finish, and the previously concealed concrete slab used as the floor finish.  Hot-rolled steel wall cladding wraps the main counter which is finished in polished concrete.
