Intergenerational Symbiosis: Empowering Communities through Participation

Intergenerational Symbiosis, in a holistic sense, fosters reciprocally beneficial relationships between ecological actors through cooperative interactions. The model pioneered by the Edinburgh Student Housing Co-operative (ESHC) exemplifies this through a democratic, decentralised, and self-governed structure that promotes shared responsibilities and support systems amongst residents. Building on the cooperative ethos of mutual aid, this project proposes an architectural intervention for intergenerational living at Astley Ainslie Hospital. The proposal employs handcrafted 3D-printed earth blocks for modular construction. This tectonic system,  developed through extensive material prototyping and a live-build project for the co-op members, accommodates, through a variety of module sizes and designs, the residents’ DIY skills, while allowing personalised space modifications that reflect each inhabitant’s unique character.

The proposal organizes and adds to the existing buildings in three linear zones: one for students, on for elderly residents, and a central ‘intergenerational symbiosis generator’—a communal hub fostering interaction and the sharing of spaces and activities. Envisioned as a phased, participatory construction process, the design enhances feasibility while allowing residents to directly influence their living spaces and communal environments.

The project ultimately aims to create a supportive, vibrant community that, through the progressive construction, maintenance, and modification of the building, encourages mutual assistance, exchange, and empathy.

EDINBURGH ECO-PAVILION: Pre-fab Raw Earth Modules with Adaptable Design

The Edinburgh Eco-Pavilion, developed for the Edinburgh Student Housing Co-operative, features an earth-based modular construction system offering a democratic, student-run housing alternative. The project creates a live-build structure in the existing courtyard, providing a sheltered space and seating area for students to enjoy and potentially replicate or modify in the future.

In collaboration with co-op members and considering the site’s conditions, the design process involved experimenting with earth prefabrication. The walls consist of prefabricated blocks made by layering strips of fiber and raw earth into molds, akin to 3D printing. These blocks are designed to optimize stability, strength, and drying times, while their lightweight nature facilitates easy transport and assembly. A timber roof is integrated into the walls, forming a structurally supportive ring beam.

The pavilion’s modular design allows for adaptable wall functions and aesthetics, supporting changing needs. Strategic gaps in the stacked modules permit interchangeable functional inserts like seating or storage, secured with diagonal braces. This adaptability makes the pavilion versatile for various activities, including social gatherings and relaxation. The system’s flexibility also suggests potential applications in emergency shelters, event spaces, and community centers.
