Building for hotel use located near the conference center of Barcelona, on the corner of Calle México and Gran Vía. Architecturally, we should mention the free disposition of the window openings together with the distribution of the width of the panels that maintain different widths and different positions that do not coincide with any of the vertical joints. On the contrary, the horizontal joints maintain alignment with an off-cut at great height that coincides with entire panels from the lintel to the parapet and from the parapet to the lintel. We can highlight the transparencies in the panel cladding on the loft floor that permit the entrance of light in combination with double cladding of granite and glass. The system used to support this panel cladding was PF-ALU/HPL.
