Onyx Multipurpose Building, Sofia - Case Study

The project Onyx is a commercial, multi-purpose building of height 30m that is cladded with 30mm thick Granite and Limestone. The major challenge was that the substrate being a composite wall panel, was not structurally admissible for fixing the substructure.

BILDA turned the challenge into a major success by fixing the cladding system to the mullions of the CW units through a bespoke framing profile. This eliminated the need for brackets and additional struts. The substructure quantity was reduced by 30%, thus reducing the cost and installation time too.
