Architecture studio OODA has completed the Arena Liga Portugal in Porto, cladding the building in a hexagonal white metal skin inspired by the surface of a football. The 13,200-square-metre structure houses the headquarters of Liga Portuguesa de Futebol Profissional and integrates offices, an auditorium, a football museum, and an indoor pitch under one roof.
Located north of Porto’s city centre, the site had been described by OODA as “fragmented” due to its discontinuous urban context. In response, the architects introduced a large plinth to unify the setting. This base accommodates public amenities and is topped with a green roof that connects seamlessly to the adjacent riverside park, forming a landscaped buffer around the building.
“The building sits in a fragmented part of Porto, where the urban fabric is discontinuous. The proposal responds by establishing new relationships between built form and landscape,” said OODA.
Merging Form, Function and Identity
The upper structure, appearing as a white cube elevated on the plinth, houses six storeys of glazed offices. A screen of hexagonal white metal panels wraps around the volume, referencing both the pattern of a football and the netting of a goal. It provides shade while creating a dynamic visual texture, especially when illuminated at night.
“The suspended white cube defines the architectural presence of the building. Its form distils the idea of institutional strength into a singular volume. Its skin introduces rhythm, texture, and symbolic resonance,” explained the studio.
From the north-eastern park, the green roof extends around the building to create a public garden. The entrance courtyard, carved out of the plinth, leads to a transparent reception area and gives access to the auditorium, museum, and indoor pitch.
Light and Landscape as Architectural Elements
OODA emphasised that light played a central role in shaping the design. The interplay between glass and panel geometry allows the facade to respond to sunlight, producing rhythmic shadows and visual movement throughout the day.
“Light was treated as a building material. Glazing and panel geometry capture and modulate natural light, introducing movement across the facade throughout the day,” the architects noted.
“The green roof performs as both park extension and infrastructural canopy – creating a space of transition between civic activity and formal program,” they added.
The Arena Liga Portugal offers not just a functional headquarters but a civic space that connects the league more directly to the local community—through both symbolism and public access.
