On November 23, Nina Siegethenthaler and Joe Zahm of Turks and Caicos Sotheby’s International Realty, listing brokers for the iconic Arc Penthouse, were proud to attend the topping-off ceremony alongside the Windward team. It was a privilege to be part of this meaningful occasion for South Bank Resort as they reached a pivotal point in the project’s construction.
They were joined by the remarkable Piero Lissoni and the talented Windward TCI group. The Topping-Off ceremony marked an important milestone for this groundbreaking development. Reaching the highest point of construction is more than a structural achievement—it represents years of thoughtful planning, creativity, and collaboration coming together in tangible form.















Moments like these provide an opportunity to pause, reflect, and appreciate the collective effort behind something truly special. Hearing Piero speak about his vision for Arc was especially inspiring. His approach—deeply rooted in community, shaped by the natural landscape, and guided by the shared dedication of everyone involved—was both thoughtful and powerful. His humility and clarity of purpose are reflected in every line of Arc’s design, reinforcing why this project truly stands apart.

More epic achievements are still to come, and this milestone is just the beginning.
