Earth and water textures from the VANGUARD range have been used. The first in a graphite grey colour which was very useful for resolving "the point where the building meets the ground, giving it a more solid character" and the second one was used in white "to give the building a lighter, more dynamic feel".

The spectacular optical effect generated by the water texture creates the illusion of different shades in the same colour. It is in fact just one colour that achieves the effect of various shades thanks to the waves finish of the water texture fitted in different directions (vertical, diagonal and horizontal). "Just by changing the layout of the panels on the facade, we have managed to give the building a dynamic effect, since, depending on the quality and impact of sunlight on the facade, we can view different images of the same object. Fantastic", said Carlos Galiano, the project architect. 

In addition, the architect has been able to create a specific and personalised design in the perforation of the panel in both textures, creating "a microclimate that revolves around natural light" on the staircase, without changing the composition of the facade.
