The Ribera Market, Bilbao (Spain)
The Ribera market, next to the Bilbao Estuary, is a major market in Spain’s Biscay region. Since it was created in the 14th century, this municipal market welcomes food producers and traders from the entire region and every conceivable foodstuff is sold here. It wasn’t until 1929 that a reinforced concrete building, the first of its kind at the time in Bilbao, was constructed to house the market. Designed by architect Pedro Ispizua, the building features an eclectic Art Deco composition. The building underwent numerous changes over the years, the last of which were made after the 1983 floods. It wasn’t until 2008 that the municipality decided to renovate the building entirely, awarding the project to Emilio Puertas Tejedor.
When the implementation plan was being developed, a diagnosis was requested and it revealed serious problems with the existing structure: the overall deterioration of the building’s frame due to damage from chloride (caused by proximity to the sea) and insufficient load bearing capacity in terms of current standards.
Architect: Emilio Puertas Tejedor, Estudio EPA
Client: Municipality of Bilbao
Technique: VMZ Standing seam
Surface aspect: QUARTZ-ZINC®
The original building features three levels (one of which is semi-underground). It is 130 metres long and 30 metres wide. Its symmetrical composition is made up of five parts: a central body topped with an octogonal glass roof framed by four towers, two wings on the sides and two apses, each ending in two towers.
The Ribera market is a covered market. The ventilation necessary in the slaughtering areas is provided by natural ventilation, using the concept of a semi-open building, which makes it possible to reconcile air renewal requirements with temperature control in the retail areas.
