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.
