The project for the micro-winemaking space for a Cava Maker in Subirats, Barcelona, pursues the council of the estate’s big rock in the shadow – oriented to north –, which faces Montserrat mountain and hosts a natural water mine, with the current and future winery. The existing winemaking constructions appear aligned to the original Catalan rural cottage, the founder’s family Masia, on top of this unique rock, reaching an undue presence on the landscape. To bring a smoother image of the whole winery and enhance the significance of the Masia, a new building for experimentation and micro-winemaking is proposed to restructure the series of preexistent buildings and rephrase its dialogue with the environment. The building embraces the rock and highlights it, while it provides a new green path to the winemaking area, to bring harmony within the context and set a narrative route for visitors. The new micro-winemaking space sits on the skirts of the rock to bring the texture of the stone into the new building while it controls the access to the water mine and frames the natural beauty of a rocky wall as such.
