The windows on all four sides of Casa Botines are identical. They decrease in size as they go up the building. Exterior moldings differentiate between the floors and emphasize the width of the building.
The construction of Casa Botines took only ten months, despite Gaudí's troublesome relationship with the people of León. Some local engineers didn't approve of Gaudí's use of continuous lintels for the foundation. They considered sunken piles the best foundation for the region. Their objections led to rumors that the house was going to fall down, so Gaudí asked them for a technical report. The engineers were unable to come up with anything, and were thus silenced. Today, Gaudí's foundation still appears perfect. There are no signs of cracks or settling.
