Designed by EMa Arquitectos, the assignment was to build a small house for the keeper of a farm which corresponds to an ecological reserve in the urban limit of the city of Santiago. The location of the house was chosen to meet project requirements and to optimize the sunlight. Located in Los Domínicos, Santiago Chile, the place, despite being private property, was to have free access to practice mountain biking. The rural condition of the place, the weather and the idea of creating a point of access and control to the place, led the architectural typology of the house. This worked on two concepts: dark vertical roof and natural colored wood walls. These conditions, in addition to the black colored windows, allow the house to be a neutral building in the natural environment. The red access door contrasts with the rest of the house.
