Claris 89
Rehabilitation of Nubiola building at 89 Pau Claris Street in Barcelona materializes as a comprehensive intervention that transforms a residential building constructed in 1872 into an office building. This transformation respects the essence of the original structure while embracing sustainability—nothing is more respectful than restoring what we already have to give it a second life. The result transports us to the architecture of the past, infused with the technology of the present.
The design of the new façade is a reinterpretation of the original, responding to the site's history and the surrounding geometry. An extension, designed to mimic traditional wooden shutters in the form of copper slats, rises three stories along Gran Vía de les Corts Catalanes and two stories along Pau Claris Street, ensuring harmony with neighboring buildings. The façade maintains the verticality of the openings, restoring the originals on the ground floor, former semi-basement, and first floor in an alternating composition that allows for multiple access points to the building.
The building features two original stair cores. The primary core, located on Pau Claris Street, provides access through a double-height lobby leading to a rear courtyard with a green wall and an asymmetrical olive tree, which also connects to the first floor. The secondary entrance, on Gran Vía de les Corts Catalanes, consists of a staircase and an original elevator, both crowned by a large skylight.
With a total of eight levels, the ground floor serves as the central gathering space of the building, functioning as the reception area with views of the main interior courtyard. The remaining floors, designed for office use, offer flexible and open layouts. The seventh floor includes a terrace dedicated to recreational use for occupants.
The spatial distribution ensures that the building is not an isolated structure but rather fosters a seamless connection between the interior and exterior. A central glass courtyard integrates galleries and terraces across different levels, enhancing visual connections and allowing natural light to penetrate from above. The rehabilitation also preserves cultural heritage, integrating authentic architectural elements into a contemporary design language. Features such as the Catalan vaulted ceilings and the restoration of the original cast-iron columns that support them highlight the building’s historical character.
The overall rehabilitation balances open and adaptable spaces with interior courtyards and outdoor areas, incorporating greenery, ample natural light, and ambient sounds that create a relaxed atmosphere designed for occupant well-being.
The building has achieved LEED Gold and WELL Gold certifications.
