Project Summary
This project is given merit for its approach to the resettlement of households displaced by a slum settlement upgrade. Notable in this proposal for mixed-use development is the strategy of multilevel walk-ups to encourage density and efficiency, creative landuse, the harnessing of renewable energy, as well as the provisions proposed for water conservation. Of equal merit is the way that external spaces are clustered to increase security and facilitate maintenance. Also commended is the concern for community cohesion as treated, for example, through the use of pedestrian walkways. The scheme envisions local employment during the construction process that promises to stimulate a sense of communal belonging. The use of locally available materials is applauded, as well as the utilization of recycled and waste materials. Overall the project is as convincing as it is ambitious.

Comment of the Holcim Awards 2005 Jury for Africa Middle East
The project is credited for its responsive approach to providing mixed-use development to accommodate the re-settlement of households displaced by the process of a slum settlement upgrade. Notable interventions of the project are the strategy of multi-level walk-ups to encourage density and efficiency, creative land-use, the harnessing of renewable energy, as well as the provisions proposed for water conservation.

Of equal merit is the clustering of external spaces – especially for security and maintenance purposes as well as micro-climatic control – and the reticulation for a grey-water recycling system. Also commended is the ethical stance reflected in the concern for community cohesion as treated, for example, through the use of pedestrian walkways.

Also admirable is the possibility for local employment during the construction process. This signals sensitivity to the issue of the need to empower indigenous residents and instill a sense of communal belonging. An ecological awareness is expressed with the use of locally available materials for construction – i.e., hollow port slab blocks cast on site, fired bricks, iron sheets – as well as in the considerations for the utilization of recycled and waste materials. Overall, the project is as convincing as is its ambition.
