Bodegas Protos is a long-established firm of wine-growers producing Ribera del Duero wine. The new building, which presents a modern reinterpretation of traditional winery construction, is located at Peñafiel, a small village near Valladolid in Castille, northern Spain. The winery sits at the base of a small hill surmounted by a medieval castle. Bodegas Protos already utilises the subterranean area beneath the castle with more than 2 km of tunnels and galleries used for ageing wine.
The new building is designed to process 1 million kilos of grapes and it is linked by tunnel to the existing winemaking facility, the new building consists of an underground cellar with a constant temperature of 14-16˚C for storage of barrels, as well as for bottles that are maturing and those that are ready to drink. The production level is situated above, partly buried in the ground and accommodating the fermentation and storage vats as well as the bottling plant, packaging equipment, technical areas and vehicle access bays. The production and cellar floors also accommodate administrative and social facilities–offices, wine-tasting areas, areas for social functions and a small auditorium for presentations and marketing events. The scheme also includes a stepped sunken garden which frames views of the castle above whilst also bringing natural light down into the office space. The main entrance level is for both staff and visitors and includes vehicle bays for delivery of grapes. From here, visitors can view the production floor below.
Compositionally, the building sits on a triangular plinth which fills the site. Five interlinked parabolic vaults supported by laminated timber arches, are clad with large terracotta tiles to create a light, articulated structure. This modular form breaks down the overall mass and scale to create a structure that is sympathetic to the surrounding buildings and countryside. Cool storage for the wine is created by effective use of the thermal ground mass. The south façade is protected by a nine metre roof overhang while the west façade is further shaded by a system of large, fixed brise soleils. A mixed mode air system makes use of the continental climate where high daytime, and low nightitme temperatures, give the facilty free night time cooling.
The project considered the roof of the building as a facade that can be viewed from the privileged position offered by the castle in Peñafiel. The material and constructive treatment of the roof reinterpret contemporaneously the ceramic roofs that are predominant in the area. To do so, it uses a piece of large format (300 x 1480 mm) and low thickness (3 cm) clay commercial ceramic with a natural finish. The ceramic pieces, Maestral®, is manufactured by TERREAL and It is fixed mechanically by wooden battens placed according to the curvature of the arches of the roof, making a ventilated roof possible that gives better thermal and acoustic insulation, good breathability and which avoids humidity problems.
