Rising as a defining element in West Palm Beach’s evolving skyline, this 25-story, approximately 285,000-square-foot Class‑A office tower reinterprets tropical modernism for the 21st century. Anchored by a trellis-like, burnished white precast concrete frame composed of staggered, intersecting volumes, the design delivers layered terraces that create visual rhythm and integrate outdoor spaces at multiple levels.
Perched on a peninsula adjacent to a historically significant Beaux‑Arts church, the tower re-establishes a connection between past and future. Its lower planted loggias conceal the parking levels and elegantly frame the neighboring church, while a new public green—centered on a venerable banyan tree and accented by a reflecting pool and sculptural “portal”—transforms the adjacent lawn into a dynamic civic gathering space. At the ground level, retail and dining amenities activate the streetscape and connect seamlessly to the public realm.
A hospitality-inspired experience begins with a welcoming porte‑cochère and two-story lobby. Office levels are tailored to meet the needs of diverse tenants, offering a range of configurations from expansive mid-level floors to boutique upper-level suites. The 19,000-square-foot podium-level terrace delivers panoramic water views and features lush landscaping, a fitness center, and conference spaces that extend the workplace into nature.
Designed with sustainability and climate resilience at its core, the building is LEED Gold certified. Its high-performance façade features deep-set, low-iron insulated glazing with integral precast fins that provide passive solar control, reduce cooling loads, and enhance daylighting. All major mechanical systems are elevated above the floodplain, while stormwater is managed on-site through bioswales, a reflecting pool, and green infrastructure. These features not only support long-term building performance but also enrich the surrounding ecology and streetscape.
A hallmark of the project is its advanced precast concrete façade system, developed in close collaboration with GATE Precast. Factory-assembled, unitized panels—each incorporating expansive trapezoidal glazing and precise geometric profiles—were engineered for speed, quality, and repeatability. Panels interlock both vertically and horizontally to conceal joints and maximize watertightness, while two-stage casting methods allowed the creation of monolithic corner elements. EPS core fills and CNC-cut molds reduced weight and fabrication time without compromising structural performance. Local aggregates were carefully selected to ensure color consistency and reduce embodied environmental impact. A robust, dual-seal joint system with engineered pressure equalization ensures long-term durability, airtightness, and moisture control.
This technical innovation was paired with a commitment to community and context. The building’s base houses a reading room and connects to the larger master plan’s pedestrian pathways and civic zones. Paired with mass transit access and new public green space, the development contributes meaningfully to West Palm Beach’s downtown revitalization and supports its growing identity as a premier commercial, cultural, and lifestyle destination.
