Méndez Álvaro, an industrial area that is developing quickly in the south of Madrid, is the location chosen for the construction of the new headquarters of the Spanish multinational company Repsol. The new business campus consists of four buildings that, as in a monastery cloister, are laid out around a large courtyard. This extensive green area, with communal spaces and landscaped gardens, becomes one of the key elements of the project.

With an expressive volumetric design, the building has a ground floor plus four stories, and each volume is designed as a longitudinal glass box. The offices, occupying the four top floors and visually disconnected from the ground floor, are prisms that longitudinally cross a sequence of perpendicular porticoes. The four floors are gathered two by two, so along the elevation they cross one another transversally. Transition spaces are in this way created within the enclosure of the frames, enhancing the views of the exterior.

The vertical communication cores are located at the end of each prism, aiming in this way to free up as much office space as possible. The secondary cores of restrooms occupy the central part of the floor plan, functioning as hinges to articulate the shift produced here. The floors are very deep and held by two rows of columns, one of them intermediate and visible. The resulting open-plan space ensures natural light, as well as a maximum flexibility in the distribution of spaces and workstations, in case needs should change in the future.

The facades are made up of large-sized glass panels that adapt to the structure of the porticoes without needing intermediate vertical frames, and favoring direct contact with the exterior.

The new campus has obtained LEED Platinum certification (Leadership in Energy & Environmental Design), and it features all the environmental variables required: fulfilling energy rating demands, using renewable energy (1,700 square meters of photovoltaic panels), reusing rainwater, selecting low-maintenance local plant species, ensuring minimum light pollution, using a high percentage of recyclable and renewable materials (certified wood, for instance), and favoring low-emission traffic solutions (bicycle parking, use of electric and/or hybrid cars and high-occupancy vehicles).
