About One One One Eagle Street

The site for the new tower on Eagle Street had several limitations and opportunities at the beginning of design which were addressed in creative ways through the process. An existing ramp and loading dock structure serving neighboring buildings was in place, limiting the design for the building core and column placement. Taking inspiration from the nearby fig tree groves, the structural design team devised an organic support system which transfers the loads in non-linear paths. This organic structure is expressed on the interior of the façade and exposed at the crown as a unique feature of the building.

In addition to the innovative organic structure, a “top-down” construction methodology was implemented which allowed the construction of the seven-level basement to coincide with the erection of the tower. “Plunge columns” were driven into the foundation piles from the ground level, which provided the necessary support for the towers while the basements were being excavated. This process saved roughly 6–12 months of construction time.
