American studio Graham Baba Architects has used perforated metal, blackened steel and salvaged wood to create an industrial-style, mixed-use building in Seattle, which includes a beer hall. 

The Klotski building is located in the city's trendy Ballard neighbourhood, a waterfront district with a maritime and industrial history.

The design of the three-storey building aims to draw upon the area's "eclectic vibrancy and gritty nature", according to local firm Graham Baba Architects.
Measuring 10,041 square feet (933 square metres), the building contains a tap room at ground level and an office on the second floor.
The top storey houses a caretaker's apartment and a work studio, which are separated by a courtyard.

Steel and concrete blocks were used for the building's structural system. On the street-facing elevation, the team incorporated a patchwork of perforated metal screens that slide up and down, allowing occupants to modulate levels of shade and privacy.

"Riffing on the idea of shifting uses and planes, the design takes its visual cue from a sliding tile puzzle, also known as a klotski, where the object is to rearrange tiles to solve the puzzle," said Graham Baba Architects in a project description.

Inside the building, rooms feature exposed structural elements, concrete flooring and high ceilings.
Graham Baba Architects designed a roof deck and an interior courtyard to "round out the spaces, ensuring ample indoor-outdoor opportunities"...
