HEARTY CITY brings together Health, Energy Efficiency, Artificial Intelligence, Resilience, Tourism and Aspiration, and it encompasses our planning vision for the Amersfoort area. Recognized in the Athens Charter as “The vital needs of the individual: sun, space, greenery – these are the three essential joys of urbanism… The city must ensure both individual liberty and collective benefits by mastering the distribution of space.”

We propose a healthy vision with flexibility for the ecological transformation of this industrial region. Koopelbrug is located in the North Amersfoort area, an urban-industrial area developed next to the river Eem and a transportation artery.

In order to realize the industrial transformation, the primary aim is to reshape the relationship between nature and site in this area. On the Reflection site we propose a vision of the city calls for healthy activities for all. Through a self-managed approach developed by the community, we hope to realize a flexible and free movement division, and a resilient and ex- tended natural boundary.

Intervening the site from four aspects, the first is the parking strategy, we no- ticed that the site close to the main road is very suitable to take on main park- ing function of the community, making our site into a PARKING COMPLEX. The second point is to create cycling friendly routes along the shoreline, reshap- ing the green and blue infrastructure along the bank.

The third point is the biological management near the river by setting up eco- logical boxes along the river and arranging greenery along the façade of houses, we hope that our site will become the habitat of the living creatures. Last point is the diversification of sports on river, with the similar volume of the Complement the kayak club across the river to complete the coastal kayaking trajectory.

Ecological Continuity: A truly sustainable housing project supports biodiversity and a healthy ecosystem. Our project incorporate green roofs and facades,  which not only insulate the building but also provide habitat for birds and insects. In the public Floor of our residental building, we plan to landscape with native plant species,  community gardens, and preserving existing trees or natural features are common practices. Buffer strips of greenery can also connect to local ecological networks. We are encouraged to set bird nesting boxes, bee hotels, and other smallscale biodiversity measures in new buildings to not only benefits wildlife but also inhances climate adaptation.

Social Cohesion: Aligned with Dutch social housing principles (Woningwet), we organize micro-communal nodes to dismantle “groundfloor privilege.” Ensuring vertical equity in community participation. We rethink to approach transcends spatial reconfiguration; it applies Sociaal Ingenieurschap to reimagine the highdensity social contract, transforming vertiality into a scaffold for gezelligheid. In our community sustainable housing communities often have resident associations or cooperatives that comanage facilities, organize events, and continue the participatory spirit.

Economic Sustainability: Closely tied to costeffectiveness is the emphasis on ease of maintenance and durability. Housing that is sustainable economically will be built to last, with robust construction quality. Including use materials that weather well (for example, we use CLT treated for longevity in wooden buildings). Residential composition include solar PV panels, heat pumps (often using geothermal warmth), and motion generation system or other renewable energy systems. We hope that sustainable housing projects can act as innovation hubs too, spurring local jobs in green construction, engineering, and technology.
