Prada Boutique Aoyama, Tokyo

The architectural challenge of spherically curved, frameless glazing has previously been unachievable worldwide. Following pre-qualification negotiations by the owner and architects with ECKELT GLAS, the glass units were modeled using computer software and a number of specially constructed prototypes, providing verification of the complex geometrical forms. The architects and facade company carried out many calculations and tests with ECKELT – lasting over a year – and eventually arrived at a successful modification of the VARIO system, which incorporates aesthetic as well as technical requirements such as earthquake safety, fire-protection etc. There were a total of 224 “bubbles” specially finished for PRADA.
