Far from being a drawback, this condition is enhanced and becomes an opportunity, starting to design, so to speak, the house through the roof. The alterations to the house are projected from the spatial and structural understanding of this particular cover in order to return to each of the spaces of the house, without exception, the prominence they had lost. And this is done, first, by restoring it with metal reinforcements, and then practicing a series of strategically placed perforations to introduce natural light and ventilation in order to experience more deeply the reflections of the air, that is, ultimately, the passage of time. The restructuring undertaken under the roof replaces a dark space compartmentalized in small rooms and corridors with a more luminous and fluid one; an exterior that defines an interior; a new landscape and domestic volume that is revealed through variable heights and changing light, and that overturns and relates each and every one of the rooms with the unique Velázquez sky of Madrid. The interior of the house, which runs lightly under that great roof of sloping planes, wooden beams and skylights, is projected and defined as a continuous space with loosely defined, indeterminate limits between public and private. Only the changes in flooring, from wood to ceramic, mark both the program and the use of space in each room. The domesticity is articulated and designed considering the coexistence and different simultaneities in the day to day, as a set of large rooms where the daily actions of each of the members of the household, both individual and collective, take place.
