Framing the issues
This was research was conducted to further explore and understand: 1) the different ideas and conceptual approaches that exist; 2) built typologies and examples; and 3) the different methods employed in different projects. The result and eventual output is summarized below and has led to the identification of eleven upgrading models. This document is a high-level summary of the research conducted during January and August 2016.
The research period extended over two months. The research does not in any way claim to be completely comprehensive, but rather representative. The precedent and case studies uncovered during this research stream were broadly defined along the following three streams:
To date, the three streams include more than 200 projects – and counting – from over 25 countries, initially themed according to eleven models. These include 50 unbuilt and 150 built projects.
Models and cases of upgrading
The eleven upgrading models include: 1) Material Innovation; 2) Top Structure; 3) Site and service/ core services; 4) Self-help build and mutual aid projects; 5) Re-blocking/ in-situ upgrading (& other services); 6) Transitional housing/ post-disaster units; 7) Community facilitation/ development; 8) Community-led finance facilities; 9) Public infrastructure (including water and sanitation, drainage and storm-water provision and area-based development); 10) Tenure provision; 11) Multi-scale interventions.
