jgstudio transforms public bathroom into undulating concrete installation in ecuador

Umbral installation transforms an existing bathroom in Quito

Umbral is a site-specific intervention in Quito, Ecuador, by JGStudio Arquitectura, commissioned by Boonker and Rinnova as part of a temporary architecture exhibition. The project involves the transformation of an existing bathroom into an immersive spatial installation, realized within a one-week construction period.

The design investigates the dual nature of concrete as both fluid and structural. Custom prefabricated concrete elements are used to explore this transitional state, capturing the moment in which the material shifts from motion to solidity. This quality becomes central to the spatial experience, shaping both interior and exterior elements of the intervention.

JGStudio Arquitectura explores concrete’s fluid-to-solid form

Umbral installation is composed of three zones, each drawing conceptual reference from planetary environments. The first, Earth, is a green space where vegetation emerges through concrete modules, introducing organic contrast to the rigid material system. Mars is defined by red-toned surfaces that emphasize temperature, contrast, and intensity through chromatic treatment. Saturn features soft whites and beige hues, evoking spatial clarity and a sense of expansion through lighter material finishes.

The design team at JGStudio Arquitectura reconfigures the original bathroom to prioritize spatial perception and sensory engagement. Functionality is reduced to its minimal expression in favor of an environment that encourages observation, pause, and material interaction.
