Portugal-based OODA firm has revealed the design of the headquarters of the Portuguese Professional Football League in Porto. The project evolved in two simple moments: a horizontal, green one; another objectual, white one. The ground floors establish a clear relationship of continuity with the park on the riverside of Granja. The spaces were designed for public use organized around a new square and under the green and undulating roof. The rest of the building rises above the horizontal plan in a pure and affirmative way.
