Located in Merida, Yucatan, Mexico, Tree House is a residential project completed by Taller Estilo Arquitectura. The existing structure that would have solved the previous requirements, would not cover the needs of the new inhabitants without making drastic changes. It not only respects the natural and built contexts but makes them an essential part of its character. The space was optimized reusing the entire existing structure, rearranging the areas and creating apertures capable of incorporating natural ventilation and lighting favorable for each area of the house, despite its unfavorable orientation. The new building was added on the east side, between the Zapote tree and the existing building, thus defining two exterior areas, a cozy and intimate central courtyard that allows public areas to open to the north and east, and a wide backyard surrounded by the greenery of the immediate context, where the tree is the protagonist along with the circular pool, playing with the curved shapes of the building that enable us to keep the tree.
