This is Torre Cube located in Guadalajara, Mexico. It was designed and built in 2005 by Architect Carme Pinos and her studio. Her designs mostly have some modernism to them and they usually look spectacular like this one. A well ventilated office and use of natural light makes this structure very self sufficient and environmentally friendly. I enjoy when designers include sustainability in their designs. The final cost of this project was 10 million dollars which I think is very reasonable for a structure of this size. This is one of my favorite designs by this architect.
