Ground Zero Pavilion - Concrete as Witness

Authors’ Comment

GROUND ZERO _ Concrete as Witness
An architecture of persistence and resilience, shaped by weight and absence, where reclaimed matter from sites of destruction is reassembled into a spatial expression of resistance, continuity, and material endurance.

The project received an Honorable Mention in the international Concrete Pavilion competition, 2026.

Concept & Strategy
GROUND ZERO begins at the point of impact, where destruction reduces the built environment to its material essence. Rather than reconstructing what was lost, the pavilion reassembles what remains into a coherent spatial composition. Mass, weight, and surface become its primary architectural language, allowing concrete to act as a silent witness to time, pressure, and human conflict.
The project transforms surviving material from damaged environments into an architectural system expressing persistence and continuity. The pavilion operates simultaneously as a monument and educational space, revealing the structural, material, and expressive capacities of concrete. Its assemblage-based strategy combines reclaimed fragments with a rational steel support system, creating a flexible and feasible model for reuse, recycling, and modular construction.

Materiality & Structure
Reclaimed concrete fragments from demolished slabs, walls, and columns are selected for structural integrity and surface qualities, then integrated into a modular framework of optimized steel profiles. Elements of varying dimensions function simultaneously as structure, enclosure, and exposed architectural components, generating balanced volumes and controlled spatial density.
The cruciform column system, assembled from mechanically connected angle profiles, ensures precision, reversibility, and adaptability. Adjustable fixing details accommodate irregular fragments while maintaining safety and coherence. Configurations range from central columns with cantilevered roofs to a peripheral grid based on a 4×4 m structural layout.
Vertical linear LED lighting integrated into the columns highlights textures, volumetric relationships, and chromatic contrasts. Precise finishes and detailing unify the assembly without erasing its material diversity.

Sustainability & Local culture
The modular logic enables efficient prefabrication, assembly, and disassembly. Mechanical joints and standardized profiles reduce construction complexity and facilitate reuse, while structural efficiency minimizes material consumption while ensuring durability and safety.
Excessively degraded concrete is recycled and recast into new components using reclaimed aggregates and integral pigmentation. This circular approach extends material lifespan and reduces reliance on virgin resources. Rooted in locally available materials and construction techniques, the pavilion reframes concrete as a culturally embedded medium and architectural witness. The result is a robust, adaptable system in which construction becomes an act of continuity rather than replacement.

Jury Comments

A well-developed concept with a fitting metaphorical dimension.
---
We appreciated the idea of transforming the remnants of destruction into architecture with a new identity, where the reuse of materials carries both constructive and symbolic meaning.
---
The idea is compelling, and the impact of the proposal is clear. Both symbolically and architecturally, the project stands out for its coherence and the strength of its message.
