When 62 floors accommodate 83 living units, you can presume listings will not include the words “cozy” and “poky.” This, along with the fact that Zaha Hadid Architects’ (ZHA) residential high-rise in Downtown Miami is virtually column-free inside, residents can expect plenty of room—and a glass fiber reinforced concrete (GFRC) panel or two.
Located on the water’s edge and overlooking Herzog & de Meuron’s Pérez Art Museum, ZHA’s One Thousand Museum’s curvaceous exoskeleton makes a statement. In accordance with the vernacular of condominium buildings in the city, the structural framework is all white, but that’s where the building’s flirtation with Miami modernism ends.
Instead of the once-standard stucco-and-white-paint procedure, GFRC comprises the exoskeleton’s casing. “There was an idea from the start that we wanted the architectural and structural expression to be synthesized,” said Chris Lépine, associate director at ZHA. “We wanted a very fluid exoskeleton.”
Manufactured in Dubai by cladding fabricators Arabian Profiles, 4,800 pieces of GFRC are in the process of being shipped to South Florida. Upon arriving in the Port of Miami, they are taken west to Doral, Florida, to be processed, then back to a prep yard in Miami, and finally onto the construction site.
GFRC was first used by ZHA on the Heydar Aliyev Center in Baku, Azerbaijan, where the material was used purely for cladding. In Miami, however, GFRC acts as formwork for poured concrete. This casing is assembled off-site to ensure quality control and continues its use as the exoskeleton’s finish. “It is all part of the building process, it’s not simply a cosmetic piece,” said Lépine.
Billowing at the base, gill-like forms comprise the tower’s eight parking levels. The gills act as such, providing natural ventilation to the garage area while also instigating a sense of verticality at street level. The curves coalesce and continue their way up the building, bulging at around two-thirds of the way up. Like the GFRC casing, this too was not an aesthetic choice. The wider section accommodates the structural load of the 54 floors above, including a rooftop helipad and a two-story penthouse at what Lépine described as the building’s “crown.”
While serving as a structural device and taking on the typical billowing form ascribed to Hadid’s aesthetic, the exoskeleton also produces wide-open floorplans. “We wanted it, to a degree, to reflect what was going on inside the building,” said Lépine. In addition to the penthouse, there are eight full-floor apartments and 70 half-floor units.
Much of the enclosure is set back from the face of the exoskeleton with the glazing system being abutted and sealed to the structure, thus allowing for apartments to be self-shaded. The exoskeleton is expressed inside with the GFRC entering apartments. It can also be touched. (There’s no fear of heat loss through thermal bridging in Miami.) Balconies are further recessed, “almost created as depressions behind the structure,” Lépine said, and result in the glass facade folding and faceting behind. “There is a nice interplay between the two materials, as well as with how light casts down upon the structure and fenestration,” he added.
Aside from palatial living units, One Thousand Museum is laden with luxury amenities: thirty thousand square feet of communal areas, including a two-story aquatic center, a sky lounge, a multimedia theater, a wellness spa, gym facilities, and a private event space—naturally, a “bank quality” vault is also included.
Ground broke on the building in December 2014. During the summer of 2015, one thousand trucks rolled onto site to pour 9,500 cubic yards of concrete in 24 hours to start the One Thousand Museum’s foundational work. The building is currently due for completion in 2018.

The veil functions both as the primary facade and the daylighting system, providing a sense of connection between the gallery spaces and the city.The Broad Museum will open its doors to the public on Sunday, 5 years after after Diller Scofidio + Renfro won a small invite-only design competition to design a space for Eli Broad’s immense contemporary art collection. All of the public spaces in the museum are created between the building's two enclosure systems, coined the “vault and veil” by DS+R. The veil, a daylight-absorbing concrete exoskeleton balances performance with fashion, while an interior vault protects a nearly 2,000 piece art collection. Visitors move over, under and through the vault, which consumes almost half of the 120,000 sq. ft., 3-story building. The exterior facade assembly consists of a steel frame clad with 2,500 glass fiber reinforced concrete (GFRC) panels which were precast on custom CNC formed molds. Evidence of the GFRC's digital fabrication process can be prominently seen on the main elevation where a large dimple provides a smooth undulation in the facade. Kevin Rice, Project Director for DS+R, explains this formal move was a deliberate reaction against the repetitiveness of the elevation: “We were studying the capabilities of digital fabrication and wanted to move the design of concrete facades beyond the brutalist facades of the 60s and 70s.” To construct the interior portion of the facade panels, seen below, the project team worked with Kreysler & Associates to develop a lightweight alternative to the exterior cladding. Fiber Reinforced Polymer (FRP) panels were fabricated with a finish to match the adjacent GFRC panels. Galleries on the third floor sit under 328 skylights supported from a 200’ long span structure composed of 6’ deep plate girders. The skylight monitors are designed to encapsulate the structure of the roof, the lighting system (a combination of daylight and LED), the waterproofing and drainage system, and the fire & life safety systems. All of these functions have been coordinated by DS+R to fit seamlessly within the language of the vault. Rice speaks of the benefits to this rigorously designed roof system: “The skylights are designed to maximize the reflected light from the north sky while eliminating all direct sunlight from entering the space. This allows for the tight conservation controls for the art while eliminating the need for electric light for much of the day.” The building’s siting across the street from Gehry’s Walt Disney Concert Hall notably had an influence on the aesthetics of the facade. Elizabeth Diller said she wanted the building to be strikingly different from Gehry's building: "We realized it was just useless to try to compete – there is no comparison to that building," Diller said. "We just had to do something that is mindful and that knows where it is […] Compared to Disney Hall's smooth and shiny exterior, which reflects light, The Broad is porous and absorptive, channeling light into the public spaces and galleries." What results is a wall system which functions both as the primary facade and the daylighting system, providing a sense of connection between the gallery spaces and the city.
