Interviews
Grand Interview
Timscape Indoor Landscape has earned a Bronze A' Design Award in the Landscape Planning and Garden Design category, a recognition from one of the world's most prestigious international design competitions that celebrates creativity, ingenuity, and meaningful contribution to human wellbeing. Given that this accolade specifically honors designs distinguished by their professional execution and capacity to improve lives, what aspect of Timscape Indoor Landscape are you most proud of, and which single element of the design do you believe most powerfully embodies its ambition to reconnect urban dwellers with the natural world?
I am most proud of proving that a tropical plant community can thrive long-term in a basement with absolutely no sunlight or fresh air. After more than a decade of indoor landscape practice, I have always believed that the boundary between "indoor" and "outdoor" is imposed by building conventions, not by ecological necessity. Timscape pushes this idea to its most extreme test—a 236-square-meter underground commercial space in Beijing.The single element that best embodies our ambition is the intelligent LED canopy paired with the closed-loop misting system. This is not ordinary grow lights; it is a simulated rainforest sky that follows daily light rhythms, supporting both plant growth and human wellbeing. When visitors step off the escalator into the basement, the immediate shift—from the harsh commercial space above to a humid, living green world below—creates what I call a "cognitive reset." The body recognizes nature before the mind can label it as technology. That moment of disbelief is exactly the reconnection we set out to engineer.
Urban populations worldwide are confronting the psychological and physiological consequences of living in high-density, nature-deprived environments, and Timscape Indoor Landscape addresses this challenge directly by creating a walkable, inhabitable green core within a 236-square-meter basement commercial space in Beijing. How does Timscape Indoor Landscape function as a replicable model for other underground or daylight-deprived commercial environments globally, and what specific spatial and ecological strategies embedded in the design do you believe are most transferable to entirely different climatic and cultural contexts?
Timscape is a proof-of-concept for the "underground biophilic layer"—a repeatable spatial type that can be inserted into any commercial space lacking natural light. Three core strategies make it adaptable worldwide:Modular ecosystem units. Each unit has its own soil, irrigation, and lighting. The system can scale up or down, and individual units can be swapped or reconfigured without disrupting the whole. A developer in Dubai or São Paulo simply changes the plant palette while keeping the same infrastructure.Vertical layering. In a low-ceiling basement, we create visual depth through stacked planting planes—canopy, mid-layer, ground cover, and climbing walls—making a small space feel much larger.Closed-loop resource cycling. Rooftop solar powers the LEDs; condensate and filtered water feed the irrigation. The basement becomes a metabolic node within the building's larger resource cycle, not a drain on it.
One of the most technically compelling dimensions of Timscape Indoor Landscape is its near-zero-energy operational framework, integrating full-spectrum LED grow lights, rooftop photovoltaics, and closed-loop water circulation to sustain a diverse tropical and subtropical plant community in a fully enclosed basement with no natural daylight or ventilation. Could you walk us through how the intelligent irrigation and lighting systems were calibrated to simulate a stable rainforest microclimate for this specific plant community, and what scientific principles most directly guided the multi-species selection process to ensure long-term ecological stability rather than mere short-term aesthetic effect?
Lighting: We tuned the LED spectrum across blue light (for growth), red light (for flowering), and far-red light (to prevent leggy growth), mimicking the way rainforest light shifts from morning through midday to evening.Irrigation: Soil moisture sensors and leaf wetness monitors feed a central controller that pulses mist at 60-second intervals, with UV sterilization and root-zone biofiltration keeping water oxygen levels above 6 mg/L.Plant selection: We chose by function, not just appearance. Large-leaf, high-coverage species like Philodendron and Monstera go in seating areas for stress relief. Shade-tolerant ferns, Anthurium, and Begonia form a self-sustaining community rather than a static display. The goal is a living plant community that can regulate itself, not merely look good on opening day.

- Production Technology
- The design was crafted via a synergistic methodology blending classical Chinese garden design principles with modern sustainable landscape and digital technologies. Core techniques included extracting traditional garden spatial logic, layered layout, dynamic circulation, and nature human integration, to restructure the enclosed underground space into a landscape centered green core with composite functions. Ecologically, carbon sequestering, minimally processed natural wood was adopted for structural frameworks, enabling circular resource utilization. Technologically, a customized intelligent system was integrated, full spectrum LED grow lights simulating natural daylight, automated precision irrigation drip and sprinkler, photovoltaic power supply for landscape operations, and closed loop water circulation. Plant selection followed the right plant for right place principle, with scientific multi species collocation for a stable indoor plant community. The design also applied horticultural therapy principles, leveraging plant psychological benefits to enhance human experience, unifying cultural expression, ecological sustainability and technological innovation throughout the design and implementation process.
- Design Challenge
- The greatest challenge was creating a viable, sustainable vertical garden in a fully enclosed underground space with no natural daylight, poor ventilation and limited vertical height-overcoming these inherent physical constraints while balancing cultural expression, commercial functionality and ecological sustainability. Externally, technical hurdles included simulating a stable growing environment for tropical/subtropical plants in Beijing's climate, developing a self-sufficient near-zero energy system for landscape operations, and achieving closed-loop water circulation to meet green building standards. Internally, the creative challenge lay in reinterpreting classical Chinese garden philosophy for a modern commercial underground context: translating its spatial aesthetics and functional logic into a compact, composite space without losing cultural essence, and integrating traditional design motifs with minimalist modern architecture. Additionally, aligning the landscape's long-term O&M efficiency with low-carbon goals required iterative testing of intelligent irrigation/lighting systems and ecological material applications, ensuring technological feasibility matched design vision while satisfying commercial space usage demands.
- Research
- This research is a practical design and environmental study focused on indoor landscape and underground commercial spaces. Its goal is to solve the lack of nature in dense cities, improve underground space experience, and create a healthy, low maintenance and sustainable green area. We used on site investigation, user behavior observation and plant growth testing. Tools included environment measuring devices and long term monitoring of light, ventilation and plant conditions. Participants included commercial space visitors, daily users and later stage management staff. Results showed the space greatly improved comfort, plant survival remained stable, energy and water use stayed low, and management was simple. The research showed that integrating traditional garden ideas with smart systems can effectively improve underground environments. It provides a usable model for commercial space design, promotes urban ecological development, and offers a replicable method for healthy, low carbon indoor landscape design.
- Inspiration
- This project reconnects humans with nature within a 236-square-meter underground commercial space in Beijing, addressing the loss of urban green areas caused by high-density development. Located in the basement of Beijing International Jewelry Trading Center, the site lacks natural daylight, ventilation, and vertical height.
Inspired by classical Chinese garden design principles, particularly the Lion Grove Garden, the concept creates a walkable, viewable, and inhabitable green core that integrates coffee service, social interaction, and nature education. Traditional elements are refined into minimalist modern architecture, breaking conventional commercial layouts to reduce enclosure.
Smart operation systems and near-zero energy technologies sustain the vertical garden without natural light. Intelligent maintenance, ecological materials, and closed-loop energy and water systems support low-carbon design.
The result transforms the constrained underground space into an urban oasis combining commercial function, natural ecology, cultural heritage, and sustainability, expressing classical Chinese garden aesthetics through contemporary, technology-empowered design. - Project Duration
- Design commenced in December 2022, and the project was completed in Beijing in August 2024.
- Operation Flow
- This indoor garden space works in a simple and intuitive way for daily use. Visitors can walk through and experience the green environment freely, just like being in a natural garden. The whole system runs automatically without complex operation.
The intelligent lighting and watering devices adjust themselves based on the actual needs of plants, providing stable light and water at proper times. Clean energy is used to power the whole landscape system, and water is recycled to reduce waste.
Different plants are arranged to create a comfortable and refreshing atmosphere. This design not only makes the underground space feel open and lively instead of dark and closed, but also keeps plants healthy for a long time. It brings real nature experience to people indoors, improves comfort effectively, and creates a more pleasant commercial space with low energy use and easy daily management.
