The design of X House by cadaval & solà-morales architects is the result of a constructive experiment: the technique usually employed for large-scale infrastructure construction, for bridges and tunnels, was reduced scale to meet the needs of residential architecture.
The fact of using a mixed construction technique, based on the use of high density concrete, as well as of unilateral formwork, allowed a high capacity of resistance of the concrete to be obtained in an extremely short time.
X House is perched on top of a hill in Cabrils, near Barcelona. The site on which the house was built is characterized by a steep slope and is accessible via a very narrow and steep road.
The house is on two levels. The upper level has been designed to accommodate the more private spaces of the house, designed as a suite with double bed, wardrobe, bathroom-laundry and a study.
The lower level is characterized by a clear distinction between the front and back of the residence: the former is designed to be completely open, with a floor to ceiling living space, the has internal courtyards which prevent introspection, while affording views of the sea, of the mountains and of the valley.
