The National Development Plan established the development of land for Social Interest Housing (Vivienda de Interés Social - VIS) as an objective, for which the national government "...shall give priority to the design and execution of urban macro projects to make land available for VIS, through the adequate provision of public utility services, primary and secondary road networks, public space and social and recreational equipment ". One of the goals of the National Development Plan is the development and implementation of up to 8 macro projects, including 5 for housing.
In this context, the National Social Interest Macro Project forms part of the national government''s strategy to increase the supply of social housing. This program was conceived as an instrument with which to confront the shortage of land.
Decree 4260 2007, partially modified by Decree 3671 of 2009, regulated the conditions under which the National Social Interest Macro Project should be developed, and defined the steps that should be taken in its formulation, including giving notice to the municipalities as an indispensable requirement for guaranteeing the stability of land prices.
One of the goals defined for the four-year period 2006 - 2010 was the readying of land for the development of close to 18,477 homes. To date, the Ministry has promoted 16 Macro Projects, of which 10 have been adopted, for the purpose of increasing the supply of land for the VIS and VIP programs, and the promotion of new forms of cooperation in the pursuit of more compact, ordered and productive cities with greater opportunities for all.
