Compositionally, the building is based on a light, articulated structure that sits on a solid base. The plinth anchors the building to the ground as its volume is mainly buried underground. The triangular form makes maximum use of the site and resolves the difference in site levels, also creating a horizontal plane from which the structure spans. The base of the building manifests itself externally in stone perimeter walls and pavement across the access level.

Two voids in the solid base create a large double-height space at production level and a cascading patio around the office and representative facilities. The garden brings natural light and ventilation to the offices, and generates an outdoors break-out space with framed views of the castle. The light structure consists of five interlinked vaults, which are suspended by 'V' props above laminated timber arches with an 18m span . The modular and systematic nature of the roof's structure means that the vaults can vary in length and follow the diagonal perimeter of the triangular base. The roof has been composed as a façade, since it becomes the building' s elevation when seen from the castle of Peñafiel. The terracotta tiles of the roof covering, compliments the surrounding buildings and acts as a rain screen with a ventilated cavity.

The building is a contemporary reinterpretation of the traditional winery in terms of the effective use of thermal ground mass, large flexible warehouse typology and construction materials.

The underground cellar is a 5,000 sqm flexible space for the storage of barrels and bottles containing ageing wine and has adjacent facilities for barrel cleaning, an historical wine archive and areas for staff. The 7.5 metre high space has an intermediate mezzanine surrounding the sunken patio that hosts the social facilities – wine-tasting room, lounge, multi-purpose space and a small auditorium. These spaces have views to the external garden and elevated views of the barrels and bottles.

The production level is situated above, and is also partly buried in the ground. It accommodates the fermentation and storage vats as well as the bottling plant, packaging equipment, technical areas and vehicle access bays. The administrative facilities are on both this level and also arranged around the patio.

The main entrance level is on the plinth of the building. It is accessible from street level on the north side via a gentle ramp, and allows for tractors delivering the grapes during the harvest on the south side of the building.
