Herzog and de Meuron (no website!) have unveiled renderings of their new 50-story glass pyramid in Paris, scheduled for completion in 2012. The building will house offices, a conference center, a hotel and some restaurants. The tower is designed to be powered by solar and wind energy. I can’t really tell from the renderings, but I think it’s interesting that the building is so wide in one direction, yet seemingly thin in its depth – more an extruded triangle than a pyramid, if that’s the case.
