The old Can Surís factory was built around 1897 and is listed in the Architectural Heritage Protection Catalogue of Cornellà de Llobregat, due to its historical and typological value. It is located in Plaça de Can Surís, s/n in Cornellà de Llobregat, next to the old road that linked the towns of Cornellà de Llobregat and Sant Joan Despí, in an area of recent urbanisation and remodelling, with the passage of the new TramBaix train. The building was unoccupied and abandoned, empty of any type of pre-existing facilities, and in a process of accelerated degradation due to lack of maintenance. The work was carried out in three phases between 2001 and 2009. The first phase included the complete refurbishment of part of the structure, the façades and the roof, and the renovation of another part of the structure, to be used as a public facility, but without a clear specific programme. This first project included new vertical communication spaces – main staircase, lifts and emergency stairs –, services and facilities for an unspecified programme, but which required a high degree of flexibility on the different floors. The second phase developed the programme of use on the ground and first floors, with the necessary interior fittings, as well as the specific fixed furniture. The project envisaged the provision of the necessary spaces to develop the programme of the new Citizen Innovation Centre for the Knowledge Society, in its sections: social dissemination-dissemination (ground floor), polytechnic learning-development (first floor) and finally digital-media realisation-production (second floor), which would be executed in the third phase. This programme called for a high degree of flexibility on the different floors in order to be able to adapt over time to the introduction of new technological developments. The access was reinforced with the construction of a double-height linear porch attached to the main façade that allows a friendlier reading of an industrial building, while serving as a filter between the activity container and the exterior access and leisure space. This steel and glass pergola contrasts with the solid brickwork and gives the building a new, more contemporary image; its placement reinforces the reading of the building and responds to the new use for which it is intended. The entrance leads to the foyer which is developed in the triple height of the building. This way, on entering, the character of the JOSEP M. JULIÀ public building is recognised and the magnitude of the three floors of the new centre can be glimpsed. The third phase of the refurbishment of the former Can Surís factory included the completion of the complete refurbishment of the second and ground floors, in terms of the interior divisions, services, finishes and all the installations necessary to use it for the extension of the Citilab-Cornellà public facilities. The project for these upper floors developed the new digital art programme in its realisation and production sections, and includes two sets of different sizes for multiple uses.
