Commercial strip in southern Mexico City. Flanked by two large rubber trees, it is located in a small plot with difficult access, with a maximum permitted height of 14 meters. Across the street is the famous CELANESE tower, designed by Ricardo Legorreta in 1968. These three main features are reason enough for generating an access plaza in the trees’ shade: it emphasizes views of the neighboring building and allows for a descending stair that contributes to the density of commercial space below street level. The last story is for office space, with generous green terraces in the back of the property. Modulation in the façade allows for a unified building design, as well as the opening of covered outdoor spaces that act as a porticos with different uses and heights.
