Our conceptual approach is to disassemble the typical monolithic tower into distinct individual floor volumes that can be reassembled, grouped and stacked to create a sculptural form that has a strong dialogue with both the pedestrian and a larger urban context. Visual registration of individual floors is typically lost on a tower beyond this height; however, at 24 stories, the scale of the proposed tower can still be visually measured by the viewer at street level or from distance within in the city. Consequently, individual floor volumes can be used effectively as the building blocks for the development of a tower form. The image of randomly stacked mail envelopes and mail packages provides a visual clue to the proposed tower massing.
Within the tower, single floor volumes are composed together with a variety of multi-story volumes to form a vertical stack. The low-rise portion of the tower is composed of single and double-story volumes, and multiple floors are grouped together higher up in tower to create larger volumes whose scale is more appropriate to objects in the skyline.
The large penthouse volume is composed of 6 typical floors to accommodate the specific Post Office area requirements and features a dramatic triple-height sky-gallery with panoramic views of city and surrounding mountains. The transition between each floor grouping is characterized by an alternating 3m shift to the northeast, and southwest. The alternating cantilevered volumes of the tower appear to perform a subtle dance as they extend upward from the ground.
At the base of the tower, a series of long rectangular single-story volumes are stacked and splayed along the southern edge of the site to maintain a dynamic yet substantial 4- story street wall along Avda. General Mackenna.
The ground floor of the podium is left partially open to provide a view into the site and permit the free flow of pedestrians through the street wall into a plaza entry court located at the northeast corner of the site. An elevator tower extends up from the plaza into the podium to provide direct access to the restaurants located on levels two and three.
