Architects Luis Roldan Velasco and Ángel Hevia Antuña designed this small, eco-friendly house for a retired couple located in Sangolqui, Ecuador.
One of the main requirments was to reduce the carbon footprint of the house. Therefore, solar energy was employed. Also, the house is built with a lightweight frame that allows enough natural thermo insulation to be installed in order to keep the indoor temperature of 20-21 degrees. Pumice stone is used to absorb the solar energy during the day and to release it at night. Also, the house can be dismantled and transported elsewhere if needed. According to the architects, all the materials used in the building are recyclable – after its life as a home, it can be broken down used for other purposes.
