This document presents a step forward on the research project currently under development entitled «Adaptable habitat for flood-prone areas in the municipality of Sabanagrande, Colombia»*. The work seeks to propose an adaptable spatial solution, conceived to respond properly to the conditions of vulnerability of populations that inhabit flood-prone areas. This should allow in turn for the customization of the space according to the needs of its inhabitants and the decent development of their life. It also seeks to define the spatial, functional, formal and constructive characteristics for the design of an adaptable habitat, covering the basic housing needs in flood-prone areas of the municipality in question.
