The Athens Landfill Rehabilitation project by Landscape–Roidis Studio addresses the environmental restoration and landscape transformation of one of the metropolitan area's most heavily altered sites. Conceived as a comprehensive reclamation strategy, the project seeks to convert a degraded landfill into a resilient landscape that restores ecological function while establishing a meaningful relationship with its surrounding environment.

The design is founded on the principle that post-industrial landscapes can become valuable ecological and public assets through careful landform manipulation and environmental planning. The first stage focuses on the technical stabilization of the landfill body through the reconfiguration of slopes, implementation of drainage systems, erosion control measures, and engineered soil capping, creating the conditions necessary for long-term vegetation establishment.

A defining aspect of the proposal is the reshaping of the site's artificial topography. Abrupt landfill embankments are transformed into gently contoured landforms that visually reconnect the reclaimed terrain with the broader Attica landscape. These interventions reduce the visual impact of the former landfill while creating a more natural and legible landscape structure.

Ecological restoration is driven by a planting strategy based on native Mediterranean species selected for their resilience to drought, poor soils, and high solar exposure. A layered composition of trees, shrubs, and groundcover promotes biodiversity, improves microclimatic conditions, and supports the gradual re-establishment of natural ecological processes.

Carefully integrated access routes and vegetated buffer zones further strengthen the site's environmental performance while ensuring its harmonious integration into the surrounding landscape. Rather than concealing the site's history, the proposal demonstrates how landscape architecture can regenerate environmentally compromised land, transforming degraded infrastructure into a sustainable landscape that balances ecological restoration, technical performance, and spatial quality.
