**3. Background**

In January 2019, through one of the members of the team, Dr. Angel René Estrada, communication was established with Ms. Elena Matías Molina, representative of the El Encanto community, with the aim of expressing the interest of the team of academics and students of the Faculty of Architecture, Autonomous Universidad of Chiapas, to carry out research work and develop intervention proposals aimed at improving housing, sanitation, recreational spaces, for the benefit of the inhabitants. On that visit, the first approaches were made to the town, where the lack of basic water and sanitation services, the lack of public recreational and family coexistence spaces, streets without folder, and with little lighting were observed. Most of the homes are inhabited by low-income families and were built by them with the resources available and traditionally with organic materials such as cane, wood, palm, etc., others with conventional materials with cement-sand blocks or solid brick produced on site by the inhabitants, ceilings with galvanized sheet; also, precarious housings built with waste material, such as cardboard, sheets, etc. were identified. In general, it was observed that families live in unsafe and

unhealthy conditions, there is contamination of bodies of water due to poor disposal of wastewater, presence of excrement of domestic animals (dogs, hens, etc.) and poor disposition of the excreta of the inhabitants.

With the acceptance of the community, the team of collaborators of the Academic Body Urban Development of the Faculty of Architecture of the Autonomous University of Chiapas and the Academic Body Natural Risks and Geotechnology of the Academic Engineering Unit, Autonomous Universidad of Guerrero, created the research project: *Proposal to improve the habitat of the colony El Encanto of city Puerto Madero,Tapachula, Chiapas.* In August 2019, the project was approved and funded by the Institute of Science, Technology and Innovation of the Government of Chiapas and the Faculty of Architecture, which was carried out in the period: September 2, 2019 to January 31, 2020 [6].
