The building, which is a futuristic concept design, looks like a giant rock rising from the sand. It would function as a self-sufficient city that would have a total floor space of 192 acres and a vertical garden, while 20 percent of the tower would be given to office spaces. Rainwater collection system would harvest around 45,000 cubic meters annually, according to the architects’ estimates. Solar panels would provide additional power.
