An office building on a trapezoidal site which forms part of the actions for sector 22@ in Barcelona. The floors located above grade are devoted to offices and those below grade to parking for 40 vehicles and service rooms for private use. The proposal is for a tower rising above a more solid and compact three-store plinth, aligned with Carrer Tanger. The tower section, with a rhomboid floor plan, follows the line of the chamfered corner, without slavishly reproducing it, to reinforce the slender complexity of the resulting volume. Its ten stores are separated from the plinth by a service floor, recessed with respect to the plane of the facade, so that it seems to float above the base, lending it lightness. This being a corporate building, diaphanous floors are proposed, although the possibility has been considered that in the future they could be divided up into several units. The skin of the facade is made up of panels of stainless steel metal fabric that act as perimeter solar protection (with a shading coefficient of 50%) for the interior of the building as well as contributing to the overall lightness of appearance.
