We built very tall， 8 meter high， walls around a 33×18 meter rectangle and covered the central strip， 9×18 meters. We raised the ceilingof the 9×9central square to the same height as the 8 meter high outside walls. To fill this central space with shade， we opened it to thefront and back， creating 3 meter deep porches that protect these openings from the sun， tempering the light. To either side， bedrooms andbaths.
In the front courtyard， the entrance to the house， four orange trees mark the central and main axis， flanked by low walls that hide serviceareas. In the back courtyard， another four orange trees are similarly aligned. And at the end， carved into the ground， a trough like pond stretches from side to side.
The house is the construction of a luminous shadow.
