Inventa Towers
I believe these two entries are for the same building, given their identical address:
https://skyscraperpage.com/cities/?buildingID=90328
https://skyscraperpage.com/cities/?buildingID=3123
The
50 m roof height is correct based on the Google Earth 3D imagery. I couldn't find any pictures or info of a 90 m spire. The current name of the building is
Inventa Towers and the year finished was
2003.
