Much like its paired project Castor, two factors determined the building form: the site location and the zoning regulations. The structure that emerges is formed from two skins: its interior core is in tune with traditional construction; and a steel exoskeleton covering this core. In turn, the exoskeleton has a thin, light cable structure that serves as support for vines and landscaping. This screens the interior core and gives a unique identity to the structure. This yields three distinct layers: the interior core; the metallic skin; and the band of greenery that slinks over the building, changing over time. This dynamic shifting effect of the façade produces an abstract and monolithic green form which emerges between the surrounding low rise buildings. Given the corner nature of this site, the views are not restricted solely to front and back, allowing for three facades of glass behind the green façade looking back toward central Beirut.
