Unfortunately those are mostly older visualizations. Current planning does not include any reconstruction of the surrounding area. No balustrades, no statues, no fountain. That does not mean that they will never come back though. There are a lot of people that want the statues and fountain to return.Sandstone I believe. Also, how much of the surroundings is being built? I noticed on some renders that balustrades and some green planing along the bottom of the windows was present. As well as the fountains. Is any of this happening?
There is however some good news:
The surrounding area might not be fully reconstructed, but it will take inspiration by its prewar look. Lamps and pavement for example will be historic in look. What lamps and pavement they already finished looks really traditional and elegant.
