This is a house projected for maximum efficiency of the plot in which it is located. A huge plan of development requires careful design of private outdoor space, using that fact to develop a sequence of external areas whose relationship in terms of size and scale with the external volume are as suitable as it is possible. The interior space is arranged around a large void which goes over the common areas of housing, leaving private ones in a more domestic scale. The interior space includes all the house of a glance, and it reaches every corner. The Pool participates in this space from the outside climate and contributes to eco-efficient packaging of the house.
