Rhi-Zee Garden is a bacterially integrated system that transforms a post-industrial site into an urban green space by enhancing ecological succession. Through the gradual release of nitrogen-fixing organism, microbial communities are activated, pioneer species take root, and soil bioremediation begins.
The project bridges multiple scales: nano (organism), micro (material), meso (structure), and macro (garden). At the material scale, a biocomposite is developed from hydrogel matrix and fibres. Hydrogel formulations, fibre properties, and their combined performance in water retention, rehydration, and microbial support are explored to ensure organism delivery.
At the structural scale, woven vertical modules modulate the flow of rain and sunlight, creating environmental gradients over the flat surface. These conditions support the growth and colonisation of plant species, forming a phased food forest.
The project vision is for highly managed urban landscapes to shift from controlling nature for aesthetics to collaborating with it. The garden is not a static design but a dynamic system that emerges in response to climate, substrate, and microbial activity and evolves over time.
Rhi-Zee garden explores the intersection of microbial and architectural intervention, centring on rhizobacteria as a main nitrogen fixing organism, which forms symbiosis with pioneer species.
The fiber–hydrogel composite creates a multilayered material that acts as a medium for bacterial viability. The hydrogel is a time-based element, enabling decay and growth.
Through water flow and multiple drying rehydrating cycle, the organism slowly releases to the bare soil in different stages of the plant growth.
As microbial communities stabilise in the soil, diverse plants begin to establish roots, cover the soil, and climb the modules. Eventually, the structure evolves from a primary scaffold to a canopy that embraces microhabitats.
