A plan for the in-situ redevelopment of a cluster of four Kalyanpuri slums in Delhi was prepared by the Delhi Urban Shelter Improvement Board (DUSIB) with support of CURE. The Insitu Redevelopment Plan under Mission BSUP of JNNURM, was based on a long and negotiated participatory planning process. From as-is-where-is basis, to single level housing, to consensus on multilevel development – the community made a long and considered choice. Land was measured and household data was generated for developing the plan by CURE. Commercialization prospects were examined to frame four options – incremental housing with minimal displacement with in-house services by DUSIB, upgrading with self-investment in housing supported through micro-finance, redevelopment in PPP mode, and redevelopment with commercialization to cross-subsidize housing investments by the poor. Of the four, the last was finalized. Designs for resilient housing with rainwater harvesting, composting, DEWATs and dual piping for reuse of treated sewage water, were developed by DUSIB architects and engineers, accommodating community ideas. Forty percent land was earmarked for commercial purposes to pay for the construction. 3000 houses in 7-storey apartment blocks were to be built on 3 of 4 sites. Land under occupation of the fourth slum was to be reclaimed. Part of a fifth slum in the neighborhood was also to be accommodated.
