The project was about transforming an office building into a new residential one. The building had been designed by the architect Roberto Terradas Via in 1962, and it was considered a Site of Urban Interest with protection level C in the Barcelona Heritage catalog.
After consultations with the author's children and with the need to adapt it to current regulations and the criteria of the technical code, the rehabilitation of this modern heritage is done with great respect towards the original proposal.
Respecting the compositional criteria of the façade on Rosselló Street and the façade in the Palau Robert gardens, materials such as white limestone, grey granite and coloured ceramics are restored, incorporating locksmithing and new steel joinery. Preserving the original trace, a set of pivoting windows with a vertical axis with a glass sill is created that incorporates adjustable shutters with horizontal slats inside its glass, solving issues of security, tightness, ventilation, insolation and insulation, as well as the cleaning of the glass from the inside thanks to the three opening positions of the window, 10, 30, 90 cm.
The closure of the ground floor respects the original recessed solution by adapting it to the new use of the building, emphasising the riveted iron pillar, reconstructing the old canopy and creating a new lobby with a double scope of access.
The common spaces, such as the hall, landings and interior patio, are treated with period materials such as paving stones, ceramics, wood and iron respecting the formal ideology of the Roberto Terradas Via project.
Inside the flats, the proposed distribution allows a certain flexibility and the view from the main area of the unitary set of the four windows.
The penthouses, porches and spaces between terraces, as well as the community technical installations, are arranged following a criteria of respect for the old building and the environment.
