To Calle Alcalá, facades are orderly, obedient, within the "Vano-Macizo" tradition of Madrid. At the height a respectful relationship with the buildings is kept, looking exactly for the line of the building with structural protection Alcalá 139 (exactly 698,03 higher level of cornice), and presenting an agreement between the two adjoining buildings. On the ground floor, order is placed on the local future, prolonging the open space and an impost is marked on the transition to the first floor where the transition of the existing building was.

On the façade of Francisca Moreno (the narrowest street in the Salamanca district), the building is set back as allowed by the zonal norm, so that it breaks into that alignment with a patio open to the street with glazed panes, where the glass curves do not see any carpentry from the street, and enhance the effects of reflections, nuances, depth ... In addition to functional issues, sustainability, energy efficiency, and brings considerable advantages as light of housing, street lighting , etc.

The glasses do not go from floor to ceiling but each floor is divided into two strips, a first opaque strip or "peto" where the glass is a coating, and a strip of windows, formed by curved glass that forms a relief of "flish" -flas ", or accordion folding on the facade in that strip. These curved glasses of radius of curvature 30 cm make that the union of the glass of one direction with the one of the other, does not have carpentry and the necessary hollow of window to ventilate, and cleaning of the glasses is hidden from the street view ( always in the area of ​​the flish-flash away from the street)

The nuances of colors and reflections of the glass are not capricious. Regarding the type of glass, those located in the window strips have or not solar control layer depending on their orientation. On the other hand, as regards the geometry of the façade, those located on the south façade are set back and protected by the upper lintel of the vertical blind peto on the upper floor that casts a shadow on them, while those on the north face protruding. outwards, looking for more light, and the breastplates between the glass strips in this northern area are inclined, seeking to hide the enclosure-upper dome, (its sealing and waterproofing closure)
The facade on the ground floor is materialized in the two left and right volumes that adjoin the neighboring buildings and in the central section is materialized with an upper beam and a lattice permeable to the views.
In the upper facades of the 5th and 6th floors exposed to the west, a double skin of solar control louvres is proposed to protect the direct uptake.
The solution increases the degree of lighting, sunlight and ventilation of existing homes on Francisca Moreno Street and those planned with respect to other solutions. It allows the city to hide, cover, uncover its medians and not force the houses to look towards them. Poses a future landscaping with adult deciduous trees, already planted as "specimens", more than 7 meters high and 40 cm trunk.
All the houses are exterior and all their living parts. The "geode" carved is looking to promote reflections, sun protection with vegetation, trompe l'oeil. The west and south facades will have, in addition to the solar control layers in the glass, other protections and solutions for solar protection and darkening. The set will seek to overcome the usual standards in sustainability, use of renewable energies, use of rainwater, recycling for irrigation, ...
