The concept for Blackstone Island was driven by the ambition to optimize land use while enhancing the quality of living in increasingly compact urban environments. The project explores how the spatial richness and privacy of detached villas can be preserved within a denser vertical framework. By reinterpreting the courtyard typology in section, the design introduces the Vertical Quintuple Villa—a composition of five independent residential units stacked three-dimensionally. Each unit maintains its own entrance, vertical circulation, and open-air garden, ensuring autonomy and spatial diversity. Developed through modular thinking, digital modeling, and on-site prototyping, the concept offers a new residential model that balances individual experience with collective urban form.

Situated within Chengdu’s Luxelakes Eco-City, the project is encircled by a U-shaped lakefront and integrates seamlessly into the ecological system. Its layout follows the contours of the island, with alternating masses that preserve visual corridors and maintain privacy. A 7-meter-wide green buffer along the waterfront forms a porous boundary between public and private, allowing for shared access to the landscape. The buildings, with dual façade strategies, transition from sculptural street-facing fronts to transparent lake-facing terraces, enabling architectural individuality while responding sensitively to both urban and natural contexts.
Sustainability is embedded in both construction method and material strategy. The project adopts a modular design logic that enhances precision and minimizes waste. BIM-based detailing and on-site mock-ups ensured high construction quality and long-term durability. Two façade systems employ differentiated materials—light gray aluminum panels, Blue Eyes marble, wood-grain metal, and corrugated metal—balancing lightness, texture, and low maintenance. The L-shaped rooftop terraces and sunken gardens provide passive climate responsiveness and spatial permeability, reinforcing the project’s alignment with Luxelakes’ ecological ethos.
Blackstone Island pioneers the “Vertical Quintuple Villa” typology, stacking five fully independent homes within a singular footprint. Each unit features exclusive entrances, elevators, and private outdoor areas—sunken gardens, sky patios, or roof terraces—offering individuality within compact urban density. Dual façade strategies sculpt a bold city-facing form while opening to panoramic lake views on the opposite side. Through modular massing and spatial innovation, the design overcomes policy constraints and site limitations to deliver a high-luxury, low-density living experience. With spatial clarity, construction precision, and environmental sensibility, the project proposes a new paradigm for future urban villas.
As expressed by the client, Blackstone Island was envisioned not merely as a residential development, but as a new architectural prototype responding to contemporary urban challenges. It embodies the client’s pursuit of individuality, ecological harmony, and spatial dignity. More than housing, the project represents a future-oriented model for high-end urban living that fosters both privacy and connection with nature.
