Speculative Railway Transformation in 2100

Athens Greece

Individual Studio Project|Advised by Bas Smets|Fall 2024

This project envisions the future transformation of Athens’ Metro Line 1 into a railway park system by 2100, responding to a projected 5°C temperature rise that will render much outdoor space unlivable.

The proposal reimagines the decommissioned metro as a connective landscape integrating two systems: the historic metro line and Athens’ largely invisible but culturally significant water networks.

The project uses mapping, sectionsal study and oblique drawings to extract a layered understanding traversing the ground.Nine prototypes integrate the metro and water systems for new landscapes, with reference to local materials and plants. Finally, the design is applied to two specific railway stations for a more livable, adaptive cityscape in Athens, 2100.

Design Strategy

Integrated Railway-Water System

The context study through sections extract a layered understanding below the ground. The context matrix combines metro line and water system at different ground levels to explore the possibility of integrating these two systems for new landscape.

Railway Level

Nine prototype designs incoprates different water system into railway at different ground levels. The use of water is also combined with strategies to create more microclimate comfort. These elements are extracted from local tradition and techniques with water and plants to create new public space rooted in athens ecological and cultural history.

b. Railway Semi-underground

The railway semi-underground uses terrain wall for rainwater collection with climbing plants, daylighting with local pine trees and secret garden with springs under grape pavillions. This creates semi-open space that is common in local informal landscapes.

The design for railway underground looks at larger infrastructure transformation below and beyond the metro stations. The design uses green roof with herb plants to collect water and reuse underground. The openings allows trees to grow from underground water while provides shades on ground. The swimming pool provides places for cooling in warmer climate.

Charlestown, Boston

Individual Studio Project|Advised by Claire Fellman|Spring 2024

The project envisions an urban forest system within a neighborhood to address island flooding and urban heat island. It revitalizes underutilized urban spaces, fostering walkable, connected communities.

The design integrates three forest types-pollution barriers, urban groves, and community gardens-seamlessly into the urban fabric. These forests are planned in coordination with transportation, housing, and public spaces.

Beyond climate resilience, the urban forests are productive spaces that support social activities. The tree species are centered on nuts trees. Tree growth influences microclimates, understory vegetation, and vegetable crops, while their seasonal yields inspire communal events. With their maturation over 10, 20, or 30 years, the urban forests envisions a shared future for long-term sustainability and community growth.

Spatial System

Three Forest Typologies and Urban Fabric

The project proposes three types of forests-tree barriers along the highway and streets for pollution prevention, nut-berry forests at old industrial spaces and open spaces for gathering, and halzenut garden near to the housings. These three type takes use of different current idle spaces and embeded forests into urban fabric from small scale to large scale.

Microclimate, Productivity and Evolution over Time

The design looks at the microclimate of sunshine and rainwater for the griding and gaping of the trees. The projects envisions the growth of different forests and their shade patterns and yields.

LET’S DANCE WITH SOIL

Landfill Restoration for Costal Resilience

Sangus, Boston

Individual Studio Project|Advised by Rosalea Monacella|Fall 2023

What lies beneath the soil often remains unseen and unknown. At Saugus Marsh, a site transitioning from mineral excavation to landfill accumulation, rising sea levels now threaten to unearth heavy metal pollution buried within the soil. Dance, as a metaphor, reflects the act of synchronizing with the rhythms of others—an act of collective awareness and adaptation.

Tdens along the vulnerable coastline. These gardens evolve through photomediation, plant growth, and soil erosion, morphing and relocating in response to rising sea levels. Acting as agents of change, the gardens reveal the history of soil contamination, represent ongoing processes within the soil, and foster the regeneration of new, healthier soil.

Soil Formation and Metal Pollution

The landfill and mining activities brought large metal pollution into the soil. However, there is currently no monitor at the Sangus Marsh. With the sealevel rise, the pollutions may be brought into water.

The design uses different hyperaccumulator plants to trace, mediate the soil and produce new soils. Through the time, these plants will morphy with the metal level, harvest rate, and soil movement with tide.

Cemetry Design for the nameless in Aging Forest INTO THE WOODS OF REGENERATION

Franklin Park, Boston, US

Individual Studio Project|Advised by Amy Whitesides|Spring 2023

Challenging the illusion of permanence, the project embraces death as a catalyst for ecological, emotional, and social regeneration, with trees as a medium.

Through managed disturbance, the aging canopy of Franklin Park becomes both the setting for burial and remembrance and the site of ecological and social renewal. Natural burials using fungi coffins transform human remains into nutrients, supporting new tree growth and linking individuals through an underground network of roots.

Linear clearings, marked by flowering understory trees and paths, radiate from a heritage tree, symbolizing the life cycle’s rise, fall, and rebirth. Over time, these clearings fade into the canopy, creating a dynamic memorial that evolves with the forest, honoring collective and individual memory.

Mapping Narratives in

the Shifting Extractive Landscapes

Research and Representation Project|Seminar Advised by Rosalea Monacella|Fall 2024

The dry forest system in south east Tasmania is composed of several species from eucalyptus family and native shrubs and grasses. These species jointly maintain the water cycle, soil health and carbon exchange. Animals and indigenous people find their shelthers and foods within the forest.

After being discovered by French biologist, the eucalyptus, especially eucalyptus globulus became a resource of industry. Timber industry, pulp industry and oil industry of eucalyptus developed under the market-based capatalism.

The scientific management of forestry and agriculture split plants into separate domains according to the market demands, which results in the erasure of certain species and associated knowledges. The landscape became fragmented.

Due to Eucalyptus’ flammability and high demand for water, eucalyptus monoculture has exacerbated wildfire and the drought of land. The global demand is still increasing while the land is burning.
