Pictures from last Tuesday. This is going to look really nice, especially from Yerba Buena Gardens. The panels appear to be pre-cast concrete, but I didn't get close enough to tell for sure. What's nice about this is that the glass will bring a nice splash of color to this view, but the white concrete (or possibly stone) panels fit in well with the concrete on surrounding towers. First two pics are from the mid-block paseo behind the church, and the last one from YB.
