What Future Grows From Rot? 1
hen humanity’s pursuit of AIdriven perfection turns parasitic, creativity is consumed as fuel.
By 2085, bio-prosthetics enhance the body but tether the mind to a network that drains bioelectric energy, leaving imagination fractured and disposable.
A group of innate creatives rejects this parasite. Within the ruined landscape of Papplewick, they establish a sanctuary where decay becomes strategy.
Drawing from bread mould experiments, they cultivate microclimates that rekindle creative expression while generating biofuel energy—a sanctuary where the parasite cannot thrive. Here, survival and imagination entwine in a symbiotic ecosystem where environment and creativity coexist.
The scheme operates through decay-informed growth systems, strategically deployed across the site and evolving to support new forms of habitation.

SporeGrowthinVaryingEnvironments:
Using the collected mushrooms from the site, I harvested their spores and inoculated bread slices with them. The slices were then placed in different environmental conditions, such as humid and cool settings, to observe the growth patterns and how the spores responded to each environment.

Mould in humid environments followed a growth logic that crept into shadowed areas. By mapping the site’s natural conditions, I identified anchor points from which new architectural interventions can emerge.

Is Democracy Just a Checkbox? 2
hen participation fades, democracy risks becoming an empty framework. In universities today, voting is often reduced to an obligation rather than a shared act of responsibility.
Across history, democracies have taken diverse paths, each shaping cultural identity and societal values in different ways. From ancient traditions where civic engagement was a cornerstone of citizenship to modern systems where individual freedoms often eclipse communal responsibility, democracy has continually evolved.
Typology: Civic Hub
Location: Newton Building Rooftop, Nottingham Site Area: 120 m²
This project explores how architecture can restore these lost connections—creating spaces that revive dialogue, encourage participation, and reframe voting as a meaningful civic act.
By drawing on the contrasts between past and present democratic practices, the design embodies and expresses values that can re-engage students in shaping their shared future.
If democracy had a home, what would it look like?

After exploring various zone configurations, I am now defining these areas by incorporating spatial concepts developed in Phase One into this layout. This process will clarify how each zone interacts with one another and contributes to the overall design intent.
