Making its debut on the list, the multidisciplinary built-environment consultancy SJ Group is represented here by subsidiary firm B+H’s interiors for a new training center on the campus of another corporate giant, the consumer electronics manufacturer Oppo. Part of a multiphase project that also includes a low-rise R&D building and a ring-loop connecting structure—more than 861,000 square feet in all—the 20-story center Oppo Chang’an Training Center in Dongguan, China, incorporates a hotel, auditorium, and top-floor “sky” library along with workspaces, classrooms, and training facilities. But it’s the double-height lobby that really stops the show. A freestanding staircase in glass fiber–reinforced gypsum rises treelike through the space, its flowing form a sculptural presence of upward reaching curves that meld seamlessly with the ceiling.

Organic as those shapes may be, they are the product of an intensely technical process—digitally modeled and prototyped to reconcile their fluid geometry with the practical demands of integrating lighting and mechanical systems while maintaining structural integrity. The subtly textured art-paint finish of the GRG volumes contrasts with the material covering many of the surrounding walls and architectural elements: terra-cotta tiling, chosen for both its environmental credentials and its traditional associations. Installing the ceramic cladding required multiple review rounds to achieve the precise alignment and flawless detailing the futurist setting demanded. The result is an arrival space where fabrication logic and material research are inseparable from the aesthetic experience.
