In Madrid, in the Park of Buen Retiro, you can see one elegant S. XIX building, the Crystal Palace,of architect Ricardo velazquez. This same Ricardo Velazquez have a project for ruin the landscape: a monster sphere of 250 m radius over a 100 m trunk, all in Steel, for surpass the Eiffel Tower. This project never was build, of course, and actually the Crystal Palace and his lake makes one of most relaxed scenaries of Madrid

I make this image and another three (the Paris-LeCorbusier project, the Gaudi Skyscraper and the Leonardo urban idea) for one article in Muy Interesante Spanish Magazine.

For make a good adjust, I load first a model of Crystal Palace I find in GoogleSketch (is the little yellow mesh in the wireframe view)
