IwamotoScott and Pinterest team up again for the app’s board-worthy headquarters in San Francisco. The approach of IwamotoScott Architecture, led by the husband-and-wife team of Lisa Iwamoto and Craig Scott, who had designed the tech company’s last headquarters, was to energize the space through interesting angles and views, emphasizing interior design’s subtler pleasures. The comparatively refined 150,000- square-foot environment shows how Pinterest, which boasts 200 million active monthly users, has evolved over the eight years since it was founded.
