The Gehry building in Basel comprises offices, a library and an auditorium and is - with a touch of understatement - "geometrically variable"...

The building was designed by Frank O. Gehry and seems to be about 35 meters high, 70 meters long and 45 - 75 meters wide. Praise the person who had to measure it! And for BGT, who produced all the glass in the facade. "Challenging" does not really cover our efforts here...
