Architecture graduate Stephan Sobl has designed an upside-down skyscraper to hang over the Colorado River in Nevada, right beside the Hoover Dam.

Entitled Vertical Strip, the conceptual tower would provide a casino, a hotel, a boxing ring and a concert hall, like the nearby Las Vegas Strip.

The lightweight carbon-fibre structure would be suspended from a concrete cantilever and supported by a spiralling metal shell.

Located between the dam and the bypass bridge, the tower would be accessible to both cars and pedestrians from the adjoining road.

Sobl developed the project whilst studying at the University of Applied Artsin Vienna.
