Details

Three levels on the slope: workshop and terraced beds below, kitchen, dining room and bedrooms around a courtyard, entrance and living room above. In winter, south and west glazing collects solar heat and concrete walls and floors store it; in summer, louvres and trees shade the house, a green roof cuts heat gain, and a light well and openings on several sides drive cross ventilation.
