The architectural plans already shows the use of flat glass - from Architectural Plans, L2 - NW corner:Rounded buildings bring the risk of having a series of flat panels of glass used for each curve to save money. I wouldn't get too excited until we see the cladding go up. Value engineering is rampant in this city from the cheapest to the most prominent buildings.
I like the wall. I think it adds character. The current issue is that it's just a wall with nothing visible over it and at the opening of the wall, it's just an ugly driveway. Add a beautiful building visible over the wall and a landscaped entrance, and it completely changes the character of the wall.
