A full-height unitized curtain wall distinguishes this 11-floor, 569,000-sq-ft luxury hotel. The first and second levels contain curtain wall sections composed of individual panes of curved glass, complementing the vibrancy of the surrounding neighborhood, according to the project team. Inside, an eight-story atrium features a steel chain-link accent curtain suspended from the top level, highlighting 20 circular rooftop skylights. Given its extensive length, the accent curtain was stitched together top-down in phases that coincided with removing the scaffolding from the atrium. 

The hotel’s complex structural system also is noteworthy, combining cast-in-place, post-tensioned concrete and structural steel to accommodate different column grids for the below-grade parking, retail and amenity levels and the guest room portions.  

Building this $165-million structure during 33 months required extensive collaboration, the team says. A dedicated superintendent oversaw the synchronized just-in-time delivery of multiple high-end materials sourced from around the world, making the most of the limited laydown area. Leading up to the hotel opening, the project team coordinated the inspection and punch-list process, ensuring that more than 360 guest rooms were ready on schedule and on budget. The collaborative spirit wasn’t limited to work tasks. Each day, the entire project team ate lunch together, reinforcing the collaborative, peer-based safety culture. The project also achieved LEED Gold certification.
