We custom developed the sloped roof glazing (the Kite) to suit the geometry of the angled planes of the roof. Its factory sub-frame has a drained and ventilated rafter system, and a continuous silicone gasket for floor-to-floor continuity of the drained rafter. We prefabricated each glazed panel with perimeter dry gaskets to eliminate the need for external access during installation.
A fully-unitised curtain-wall system facade (affectionately nicknamed the Crazy Wall) comprises hundreds of shallow-projection pyramids, pressed using a solid aluminium sheet. The system incorporates diamond-shaped inset windows.
The geometry and changing planes of the Kite facade system required great attention to detail. As well as waterproofing, we resolved all interface details while accounting for buildability and structural tolerances.
The Architect reverse-engineeded the building form to suit the site, sitting within daylight access limits without overshadowing neighbours. The Kite roof incorporates apartments and balconies, with accessible indents integrated in the glazed roof system.
We needed to ensure safety during the construction of the Crazy Wall at roof level. We did this by using a prefabricated cladding system pre-assembled in large modules, and installing it using the tower crane.
