Cities are often celebrated for their light. Illuminated skylines, vibrant streets, and glowing public spaces have become symbols of contemporary urban life. Yet for landscape designer Zitong Hui (Shirley), the most compelling stories of the city begin where the light gradually fades.
Through her ongoing project Darkness Matters, Shirley explores urban darkness not as the absence of illumination, but as a design medium capable of shaping perception, atmosphere, and spatial experience. Originally developed as her graduate thesis at the Rhode Island School of Design, the project has evolved into an independent body of work that combines landscape architecture, environmental visualization, and visual storytelling. As a graduate of RISD with years of professional experience on award-winning landscape architecture projects in the United States, Shirley combines design practice with ongoing independent research. Her work bridges landscape architecture, environmental visualization, and visual storytelling, using drawing and representation not simply to communicate ideas, but to generate new ways of understanding urban environments.
A central component of Darkness Matters is the visualization of urban darkness. Through a combination of mapping, collage, photography, spatial observation, environmental visualization, digital modeling, and speculative drawing, Shirley investigates how artificial light shapes the perception of urban landscapes after sunset. Rather than simply documenting existing conditions, these visual explorations transform invisible environmental phenomena into spatial narratives that can be experienced, interpreted, and reimagined through landscape design.
Some drawings map the gradual transition from Manhattan’s brightly illuminated streets into the darker interior landscapes of Central Park. Others layer historical photographs, urban imagery, and fragments of everyday life into collages that reveal how artificial light has transformed both the physical city and its cultural memory. Analytical diagrams reinterpret environmental information—including light intensity, viewsheds, and ecological relationships—not as technical data alone, but as spatial narratives that inform design thinking.
Pathways, tree canopies, open lawns, water bodies, changing topography, and views toward the surrounding skyline all contribute to distinct nighttime atmospheres. Instead of presenting these conditions as isolated environmental data, Shirley translates them into immersive drawings, layered collages, analytical diagrams, and spatial sequences. Together, these visualizations reveal darkness as a dynamic landscape material—one that influences movement, perception, atmosphere, ecological awareness, and the relationship between the city and nature.
For Shirley, drawing is not simply a method of representation. It is a method of investigation.
Each image becomes a way to understand how light moves through vegetation, reflects off water, interacts with topography, or changes the perception of distance and enclosure. Darkness is treated as a dynamic spatial condition with varying levels of visibility, contrast, atmosphere, and emotional character.
Ecology remains an important dimension of the project. Central Park serves as habitat for birds, insects, bats, and other nocturnal species whose environments are influenced by artificial illumination. Rather than positioning ecology as the project’s primary subject, Shirley integrates ecological awareness into a broader design framework, recognizing that environmental systems and human experience continuously shape one another.
This interdisciplinary approach reflects Shirley’s broader philosophy as a landscape designer. She moves fluidly between environmental observation, artistic expression, digital technology, and spatial design, using visualization to bridge scientific information and human perception. The resulting work exists somewhere between landscape architecture, cartography, installation art, and speculative design.
Darkness Matters also challenges conventional expectations of landscape representation. Instead of presenting the city as a fixed object, Shirley constructs immersive visual experiences that invite viewers to reconsider how cities are felt after dark. Light, shadow, reflection, movement, memory, and atmosphere become equally important design materials.
As cities continue to become brighter, Darkness Matters suggests that darkness deserves equal attention—not simply as an ecological resource, but as an experiential quality that enriches urban life.
Through visualization, storytelling, and landscape architecture, Zitong Hui (Shirley) proposes a new way of seeing the city at night—one where darkness is no longer an absence, but an essential part of the urban experience.
