HHH housing project is located in the close outskirts of Jerusalem. As a result of non existing urban planing in this part of the city, the immediate environment of the project faces heterogeneous pollutant constructions. As a reaction to its environment, the house is based on the model of traditional Palestinian courtyard houses. All functions are oriented towards the common central exterior space. Facing south, the regular repeated stone facade modules have depths that vary at each story to best protect the interior space from solar overheating.
