Our client architects is designing a large glass canopy within the refurbishment of the façade and MEP of a building in the prime rental area in the city center of Madrid (Spain).

The new lightweight glass canopy will replace the existing heavy old canopy. For this, the cantilevered glass beams are structurally embedded into the metal secondary structure of the previous canopy.

Both, the glass parapet and the glass panes that conforms the floor, are fixed to the cantilevered glass beams.The system is completed with an interior drainage channel and two 3d rigid frame of stainless steel at the ends to collect lateral loads.

This paper describes the lessons learned when using structural glass to carry out the design of a canopy integrated into a new façade.
