'522' is not only a collaboration between two practices Ron Arad Architects & Issho Architects, it is a bridge between east and west, a bridge of disciplines, putting art into the set of very tight building law restrictions, morphing comfort of living and light penetration with pure design. Both facade and building were designed and modified hand in hand, a few times to comply and give the best impression in the narrow street and define exterior spaces whilst providing temperature control to the building.
