The architect Jaume Falguera, in charge of this task, seeks to enhance the work of Josep Puig i Cadafalch. The aim of this rehabilitation process is to recover the essence of the Modernista building and the figure of Puig i Cadafalch. On the ground floor, after eliminating the dividing walls and ceilings, the resulting open space revalues the original columns that the architect introduced to replace the bearing walls, one of the most important contributions of the time.
Three floors The rehabilitation works being carried out in the building 420, located in the corner between Avinguda Diagonal and Carrer Rosselló, are being conducted on the ground floor, the main floor and the roof. One of the main changes will be the addition of a lift that will communicate these three floors. Refurbishments are also being conducted on the ground floor to recover the essence and the main features of the original building designed by Puig i Cadafalch. Thereby eliminating the false ceiling and the different walls that had been added in the latest reforms, where there is the will to reclaim the space as an open plan area. Therefore, the columns placed by the original architect, which was the most important innovation of the time, will regain prominence. At this time, the entire base structure endured traditional load-bearing walls, but Puig i Cadafalch replaced them with different columns. With these rehabilitation works, Falguera will leave a maze of columns on the ground floor that opens up to the plaza in front. Furthermore, when removing the false ceiling you may again see the different details and ornaments that Puig i Cadafalch placed in different arches that formed the roof, which so far remained hidden. This is Casa de les Punxes main facade on the ground floor, since Puig i Cadafalch conceived it this way because it is where the two longest building facades end. Likewise, this is the best view of the building from the intersection of Passeig de Gracia and Avinguda Diagonal. From the ground floor, stairs are built that (next to the new elevator) take you directly to the main floor, which is also being rehabilitated. Space is being recovered on this floor also as conceived by Puig i Cadafalch, and emphasizing the triangular balconies and the various rooms. The main floors of the three buildings were intended as housing for each of the owners. One of the innovations being implemented by Falguera is the communication between different rooms, so that a connection between them is created. Various Spanish and multinational companies, including Cloudworks and
Roman, have set up operations at its facilities. Roman, the Spanish communications and public affairs consultancy, has established its headquarters on the two main floors.
The rooftop The building is crowned by the roof of the house, where there are six towers that grant the popular name of Casa de les Punxes. The roof is an open space plan with an area of over 600 m2, on the laterals the previously mentioned ancient bunkers and towers are located. The largest tower, occupying the corner of Avinguda Diagonal with Carrer Rosselló, contains three levels and offers a privileged view of the city. It is also in this tower where one of the great technological advances in the world of architecture is captured, a constructive revolution, in which the architect takes to the extreme the structural advances: the floors no longer rest on vertical support elements, but by hanging steel straps operating tensile loads and transmit the weight of the ceramic circular perimeter walls, making them work in compression. This structure, despite being in a confined space is accessible, an important fact to understand their constructive complexity. ==See also==
