This striking modern structure cuts a profile every bit as sleek as it is streamlined for efficiency. It is composed of four single family units joined by a flowing fusion of glass and “smog-eating” photo-catalytic concrete, creating a series of separate yet structurally connected spaces. Italian architects Iosa Ghini Associati designed the residence to integrate seamlessly into its sweeping Mediterranean landscape, and its airy day-lit interiors benefit from a slick set of green features including adjustable solar panels, rainwater recycling, and a heat storage system.
