Entropic Garden
Nature-Based Urban Shelter
Madrid, Spain
2023

Built over anthropic landfills — low in compactness, unstable, and unsuitable for solid foundations — the site suffered from severe terrain settlement, which damaged pavements and structural elements, persistent moisture and leaks that compromised homes and underground parking, and poor accessibility in its communal areas. Formed predominantly by construction waste and debris, this chaotic, man-made substrate left behind a fragile and shifting ground.

Located in Madrid’s Valdebernardo neighborhood, the project is embedded within a manzana cerrada — a closed-block residential typology organized around a central courtyard. It is in this shared interior garden that the most critical issues emerged, turning what should have been a space for community and repose into one of discomfort and degradation.

The project was initiated to address three urgent challenges within this courtyard: differential terrain settlement, inaccessibility of communal areas and recurring dampness and water infiltration

Inaccessibility of communal areas
Recurring dampness and water infiltration

To tackle these challenges, the intervention embraces Nature-Based Solutions (NBS) that respond to, rather than resist, the site’s entropic conditions. All pavements are restored, replacing rigid, impermeable surfaces with porous, adaptive materials. Compromised waterproofing systems are repaired, and a continuous perimeter drainage system is introduced to collect and return rainwater to the soil, enabling responsible water management while nourishing the garden’s ecological base.

 

The garden’s topography is reimagined as a soft, absorptive landscape. Drainage systems are resized to allow slow water infiltration, and green areas are expanded to maximize permeability. A carefully selected palette of native and adaptive plant species is introduced — chosen for their environmental resilience and their capacity to establish a self-regulating ecosystem.

 

This new vegetated layer goes beyond aesthetic enhancement — it regenerates. As it matures, it invites pollinators, birds, and small animals, contributing to a measurable increase in local biodiversity. The garden becomes not just a restored space, but a living, evolving organism — absorbing, filtering, transforming, and giving back to its surroundings.

The project is structured around three strategies that respond to the site’s inherent instability:

By concentrating activity in a single, strategically located zone, the intervention minimizes the area requiring structural stabilization while maximizing social potential. This focused layout creates a generous communal space, furnished with elements designed to foster interaction, conversation, and everyday exchange among neighbors.
The project introduces a soft topography that negotiates the uneven terrain caused by differential settlement. Rather than masking the irregularities, the new landscape absorbs and works with them — creating a gentle gradient that improves spatial continuity while p rotecting the privacy of ground-floor dwellings. By subtly raising the garden’s active level, the intervention pulls communal life away from the residential façade at ground level, softening visual and acoustic intrusion and reshaping the garden as a more intimate, layered space.
A curated layer of vegetation is introduced to stabilize the soil and prevent erosion caused by surface runoff. Beyond its structural role, this living cover modulates solar exposure, reducing ground-level radiation and enhancing hygrothermal comfort , mitigating heat island effects and improving long-term climate performance. Thus, vegetation not only protects the terrain but also invites residents to inhabit and enjoy the communal space more frequently, reinforcing its role as a shared and resilient environment.

At the heart of the intervention lies a new accessible route that weaves together entrances, play areas, and gathering spaces. Designed to be inclusive for all ages and mobilities, this path offers a safe and welcoming outdoor environment for everyday encounters, spontaneous play, and seasonal events. Shaded rest areas, tactile surfaces, and playful elements enrich the experience while fostering a culture of care, coexistence, and shared stewardship.
