Soccer balls don’t typically score points when it comes to office decor. Unless you work at TKEZ Architecture & Design Architekten, which recently completed the Berlin headquarters of Onefootball, an app for followers of leagues worldwide. TKEZ placed goal posts at the ends of the L-shape floor plan, hence those soccer balls whizzing by. To direct, err, foot traffic through the 16,000 square feet, there’s a sporty green “running track” rendered in nylon carpet. To one side, an “arena” seats 60 on bleachers, while LEDs change according to club colors.
