The site borders El Bosque Avenue and two smaller streets. Its virtual southern boundary is Tobalaba Avenue, which diagonally crosses the area along with the San Carlos Canal.
The project includes two long volumes that form a gallery containing the entrances. One volume attached to the neighboring building has three levels, while the main volume has 17 levels and is 75 meters long. This volume curves on its western facade to align with the axes of El Bosque and Tobalaba. The acute angle it creates serves as the symbolic beginning of El Bosque Avenue.
The building was divided vertically, with the lower floors for the Consortium and the upper fourteen for rentals. Both areas have independent vertical access and circulation. The entrances are at the ends of the gallery. The Consortium is entered from the south, while the rental offices are entered from the north, on the second level. This area has balconies above the first, making both entrances visually connected.
The treatment of the facades deserved special attention. Santiago's westward orientation causes serious heat problems in the summer. Therefore, the building used technical and natural means, producing a double facade: an interior one with thermopanels and an exterior one with vegetation. This "double plant skin" reduces solar absorption. It also transforms the building into a vertical garden of approximately 2,700 m2, equivalent to the gardens of the houses that stood on the site. The pre-existing greenery metaphorically rises vertically. This vegetation brightens the building and gives it a changing appearance throughout the seasons. The two upper levels of the building are protected by a large metal visor, which acts as a crown for the building and protects the upper level.
