The dynamic one-storey helical 'introverted house' by spanish firm XPIRAL rejects the less-than-exciting surrounding landscape and instead creates a central green courtyard around which all program radially unfolds.a composite concrete, steel and wood structure transitions into one another creating a cyclical sequence of spaces and a receptacle for capturing the subtle nuances of light, being transformed by its constantly changing qualities. each material allows a different nature of space, as the heavier concrete uses its thermal mass to both cool and heat the main living areas, slightly cavernous in nature; steel trusses create thin peripheral elements that bring the user closer to the exterior, and timber components add warmth and balance to the more industrial elements. a corridor is cantilevered off of the main mass wrapped in a micro-perforated corrugated steel skin that allows the free passage of air but maintains a certain level of privacy to the rooftop swimming pool beyond, enjoying all the direct sunlight possible. this suspended element also defines a threshold that can be crossed underneath on the pixelated green property adding another experienced dimension to the residence.
