MZA is proud to announce we have won the international OCT Sanya Competition! We are currently in Design Development of the over 74,000 m2 leisure campus. Buildings include numerous hotels, retail pavilions, entertainment corridors, and office space on the 37,000 m2 site.
The OCT Sanya East Coast Project is a nature-integrated urban development inspired by the tropical ecology of Hainan Island. Drawing from the metaphor of a coconut tree, the masterplan organizes three distinct program zones—hotel, entertainment, and office—along a central north-south “experience spine” that connects to the adjacent wetland park. The architecture emphasizes soft forms, woven façades, and lush vertical greenery to blend built and natural environments. Through layered terraces, organic massing, and immersive landscape corridors, the project redefines the urban edge as a socially vibrant, ecologically sensitive extension of the park itself.

The “trunk” represents the central retail and pedestrian spine—active, lush, and vibrant—anchored by cultural and office components at the base. The “fronds” or “crown” stretch outward into super-luxury residences, resorts, and villa zones, symbolizing both spatial expansion and increased exclusivity. This palm-inspired form reinforces the project’s tropical identity while organizing programmatic diversity in a legible and evocative manner.
A meandering spine forms the project’s circulation and organizing axis, connecting key zones such as the theme hotel, apartment hotel, office building, retail plazas, and “stacked” villa courtyards. Strategically placed sunken plazas activate the lower levels and link to underground retail, while green roofs and layered terraces blend architecture with the landscape. Bridges extend toward the adjacent wetland park, enhancing permeability and reinforcing the development’s integration with nature.


the vibrant character of Lot 1 in the OCT Sanya East Coast development, where a dynamic retail street animates the ground level and luxury villa units are thoughtfully integrated above. The retail frontage fosters an active urban edge, with transparent glazing and inviting storefronts encouraging pedestrian engagement. Above, stepped terraces and articulated massing accommodate the villa units, which enjoy elevated views and enhanced privacy.
At the center of Lot 1, a landscaped canal and pool draw the courtyard together, framed by timber-clad facades and layered balconies that carry the tropical modern language from ground to rooftop.


Lot 2 grounds itself in a timber-screened retail base, its vertical wood fins giving depth and shade to the street edge below. Above, cantilevered balconies step back in tiers, softened by cascading greenery that spills from each level. The composition resolves at the roofline in a faceted white trellis, lending the massing a sense of lightness and transparency against the sky.
At street level, slender columns lift the building’s glazed retail frontage back from the promenade, giving the ground floor an open, arcade-like transparency. Above, tiered balconies cantilever outward, their undersides finished in warm timber tone and softened by trailing greenery. A palm-lined walkway carries pedestrians past the base, with the city skyline receding into the evening light beyond.


The Lot 1 hotel unfolds along a gentle curve, its timber-fin facade rhythmically dividing terraced balconies planted with cascading greenery. A ground-level arcade of retail and lobby space opens onto the drive below, framed by a broad lawn and rows of mature palms that carry the building’s curve out to the street.
At dusk, the tower’s rounded form rises above a lit water feature, its timber-fin facade banding each level of terraced, planted balconies. Ground-floor retail spills out beneath red umbrellas along a palm-lined promenade, where fountains and warm lighting draw pedestrians into the building’s base.


At golden hour, the tower’s stepped white terraces rise in a tapering pyramid over a timber-screened base, each level ringed with planting. Palms frame the view from a broad lawn, where the building’s glow and warm evening light draw people toward its base.
