As the younger generation moves to larger cities for work, the elderly and children remain in underused residential areas, disconnected from productive labor and daily interaction.“Naturopia” proposes an intergenerational ecosystem that restores the link between land, labor, and life. The site integrates farmland, residential buildings for the elderly and children, a processing workshop, and a local market into a continuous productive landscape.Through agricultural cultivation, shared activities, and mutual learning, the elderly regain a sense of purpose and social belonging, while children reconnect with nature and the rhythm of living production.

Although Hong’an County is a small city, it contains a surprisingly high number of primary and secondary schools, which has led to a series of social and spatial challenges. The chosen site lies on the boundary between the urban center and the rural outskirts, where the density of schools remains particularly high.

Interventions Phase One The county remained an agrarian society, where most families relied on farming and animal husbandry, the town was small in scale, and most of the land is rural. Community life was deeply rooted in collective agricultural production.

Phase Two With the Reform and Opening-up and the commercialization of housing, farmland around the county was converted into residential areas, young people moved from villages into the county town for work, and many parents and kids followed them, reshaping the county into a semi-urban settlement. +

Current Situation

Phase Three As large cities attracted the younger labor force, job opportunities in the county declined, leaving behind elderly residents and school-age children; this demographic shift produced the phenomenon of left-behind children in boarding schools and elderly people with limited social roles.

Disengagement Theory Aging often involves withdrawal from social and productive roles. For left-behind elderly, the loss of farm work and absence of family accelerate this decline, leading to emptiness and isolation. They need opportunities to restore meaningful daily activity and social participation.

Attachment Theory Stable caregiver bonds are essential to children’s emotional security. Leftbehind children, growing up apar t from parents, often face weakened attachment, loneliness, and insecurity. They need consistent emotional support, interaction, and a sense of belonging.

Site And Status

The site is surrounded by residences and schools, requires a centralized area for public activities and sports. However, the original gymnasium had some negative impacts on people.

APPROACH THE SEA Community Sports and Cultural Center Design Grade 3 Studio Work Year: 2024 Location: Qingdao,China Individual Work Instructor: Xinyu Shi & Baiyang Hou

The base is bordered by the sea to the west and is surrounded by residential areas with a running track and other sports equipment on the beach. To the east is a school. Directly opposite the base is the main entrance/ exit, where there is a large gathering of people and a high volume of foot traffic. The original building has a very closed interface on the first floor, making it difficult for people to easily reach the beach and sports and recreation areas, with a range of negative impacts resulting. The focus of this design is to meet the needs of the community gymnasium while at the same time being able to more naturally guide the flow of people to the beach and provide an outdoor gathering place, providing more public communication places for the users. The design starts from the use demand, sorting out the main entrances and gathering places, and utilizing the principle of Frei Otto's wool experiment, sorting out the best path for people to arrive, so that people can get to the beach and feel the sea more conveniently, and at the same time, meet the indoor sports needs of the people.

Status Quo:

Requirement:

The original building on the site is a long strip that cuts off movement of people from the street to the waterfront, resulting in vacant and little-used green space park recreation facilities on the waterfront.

The new building should make the sea more accessible, linking the flows on the road and on the coastal runway , creating some collection of public spaces on the site.

Road network density: 19.2(km/km²)

Road network density: 15.2(km/km²)

In modern city planning, many cities(like New York, Portland, Tokyo,and Paris) use a n ​ arrow streets, dense road networks strategy. This approach not only creates smaller neighborhoods but also improves traffic flow: the high density of urban road networks provides multiple ro u t e s f o r d r i v e r s to re a c h destinations, reducing traffic jams and preventing congestion clusters. Narrow streets link areas closely, boosting community connections and walking." In China's densely populated metropolises, the extremely low density of urban road networks is compensated by constructing excessively wide roads to ensure traffic flow. This 'wide roads, sparse networks' model results in oversized block scales and enclosed communities, making it difficult for neighborhoods separated by these roads to interact.The existence of wide roads has not improved traffic efficiency; instead, it has caused numerous adverse effects.

BUBBLE COLLECTION Neighborhood Space Renature Grade 4 Studio Work

​​The over-wide road cutting through the dense neighborhood acts like a thick wall, separating residents and streets on both sides. It not only d a m a g e s t h e c i t y 's f a b r i c a n d l i m i t s s o c i a l interactions, but also squeezes out the precious public spaces in this crowded living area.​

Year: 2024 Location: Qingdao, China Individual Work Instructor: Baiyang Hou & LIqun Ma & Xuechuan Geng

Excessively wide streets in cities physically partition neighborhoods while squeezing out public space, resulting in underutilized areas and eroded urban vitality. Our solution deploys a breathable ​​ modular system​​to transform streetscapes: by compressing roadways to reclaim marginal spaces for resident-built community workshops, integrated with smart inflatable structures that act as elastic spatial vessels — contracting daily into micro-social hubs, then expanding into largescale civic bubbles when collective activities demand.These bubbles reclaim community life for the streets, weaving oncedivided blocks into a cohesive whole through programmed interactions that thread across the roadway.

Live space


Current Situation And Issues​2

As China's economy becomes increasingly concentrated in core cities, the urban population concentration becomes more pronounced: residents from small towns are moving to big cities for opportunities, leading to year-by-year population growth and increasingly higher population density in major cities.

100m²/people

Different Stages​

Solution

50m²/people

30m²/people

However, as population density increases, public spaces in cities have not become more abundant. Per capita public space is shrinking, while overly wide roads further compress the most accessible public spaces closest to people.

​​The shrinking public spaces are causing street-level social activities to vanish — these everyday interactions have always been the lifeblood of community bonding.​

Before

Stage 1: The original street merely functioned as a pedestrian conduit , exacerbating the enclosed nature of adjacent blocks.

Stage 2:​​ Unlocking Enclosed Blocks​, enabling residents to implant self-built modules that suture divided blocks through spontaneous social stitching.​​and establish initial workshop modules​

Stage 3: Residents add new modules, taking back road space bit by bit. Across the reclaimed ground, new community spaces emerge where people reshape their neighborhood through daily interactions.

Stage 4: The roadway ultimately yields to community spaces as spontaneous activities freely unfold across the new modules.

After B y i n c re m e n t a l l y n a r ro w i n g over-dimensioned streets into a narrow-street/dense-grid system,the reclaimed spaces from this process became sites for strategically placed activity nodes. These nodes stimulate spontaneous public interactions across the road, naturally weaving connections that mend the divided neighborhoods, fostering closer community ties.

Background: Plastic Eco-System (Data source: OECD) CO₂ emissions share of buildings in global energy and process emissions in 2023

The construction sector is a major source of global carbon emissions, accounting for 36%. Among these, 13% comes from construction activities, mainly material production and building processes.

Total Usage of Plastic in 2019

In this construction sector, plastics have the longest ave ra g e l i fe t i m e — a ro u n d 35 years. This makes construction an ideal field for recycled plastics, extending material longevity and enabling long-term carbon storage within building components.

In 2019, around 51% of global plastics were short-lived products, and 36.62% were difficult to recycle, while only 9% entered effective recycling streams. This results in a rapid conversion of plastics into waste. Redirecting these short-lived plastics into long-lifecycle applications such as building components— typically lasting 20–35 years—can significantly improve material efficiency and extend the duration of carbon sequestration within the built environment.

Recycle to next Long-Lifespan

Pellets

This project responds to the global challenge of plastic waste by exploring ways to extend the life cycle of polymer materials. As nearly half of the world’s plastics are short-lived with extremely low recycling rates, the construction sector—with its long service lifespan—offers substantial potential for long-term carbon retention. The research aims to redirect discarded plastics into lightweight architectural applications, transforming short-lifecycle materials into durable building components. To enable this transition, the project bridges ancient structural intelligence and contemporary fabrication. The historical logic of the continuous arch and groin vault—where curvature naturally channels forces—is adopted as the conceptual foundation, then reinterpreted through performance-driven minimal surface geometry to achieve efficient stress distribution and lightweight structural behavior.

Based on a robotic additive-manufacturing circular recovery system, this project processes discarded plastics through sorting, washing, and shredding into printable granules, and re-deploys them into long-lifecycle architectural components using spatial FDM technology. After their service life, these components can be crushed and recycled again, forming a closed loop of “waste → granules → components → regenerated material.” This approach transforms short-lived plastic products into high-value, long-lasting building elements, enabling sustainable material reuse.


Modern remake of ancient arches

Details DIGITAL FABRICATION

Minimal Surface A minimal surface is a geometry with zero mean curvature that naturally minimizes area. Like soap films, it forms the most efficient, low-energy shape, offering smooth curvature and balanced force distribution, ideal for lightweight structural applications.

This project reconfigures an ancient continuous-arch form through performance-driven geometry and modern digital fabrication, translating historical structural logic into a contemporary, lightweight, and recyclable architectural system.

Continuous Arch A continuous arch is an ancient structural form in which multiple arches connect s e a m l e s s l y to c re a t e a u n i f i e d , s e l f supporting span. Its uninterrupted curves distribute forces efficiently and have long been used to shape vaulted and vaulted-like spaces.

Due to a lack of manpower and frequent malfunctions of the robotic arms, the entire construction process lasted from September to December and is still ongoing. There were some compromises in the design: the original printing base was replaced with a wooden one. Due to equipment issues, the error was significant, and the original dome ring's dimensions needed to be recalculated. However, overall, I fully experienced the difficulty of transitioning from design to implementation in this project, and further understood the unlimited potential of intelligent construction technology.


Timberized Minimal Surface

DAMLab Digital Tectonic Workshop 2024

Location: Qingdao, China Group member: Wenhui Mei (team leader), Yifan Zhang, Lingchao Kong ... Instructor: Xinyu Shi; Haining Zhou Honor: The Most Outstanding Participant

This project investigates the translation of minimal surface geometry into robotic timber construction. A minimal surface is characterized by zero mean curvature at every point—representing a perfect equilibrium condition and the most efficient distribution of material. Through segmentation, structural analysis, and robotic operation sequencing, the surface is discretized into buildable timber modules. The result is not only a study in minimal surfaces but also a reflection on how digital intelligence can coexist in the making of contemporary architecture.

The project integrates topology optimization and digital fabrication through two complementary components: a digital redesign of the RMIT Building 100 entrance using Ameba to generate performance-driven form across body and skeleton, refined with SubD and detailed via Aurora; and a full-scale installation realized through robotic fabrication and AR-assisted assembly on campus. Together they establish a continuous workflow from algorithmic conception to physical construction, demonstrating structural intelligence, material logic, long-term resilience and usability.
