Correa's scheme for PREVI development concentrates on two major design ideas: that of the minimisation of service infrastructure and the use of climate as a temperature regulator. This, in layout terms, resulted in buildings which are staggered along a community spine. The staggered party wall also provided greater earthquake resistance. As in earlier schemes, the unit is a long "tube" of interlocking row housing. Each house is also incremental. The NNW-SSE orientation of the houses allows the prevailing winds to travel along the axis of each spine. As the breezes pass the porches they are drawn into the houses by a louvered air-scoop over the double-height 6 meters 6 meters volume within each unit.
