Coderch 9: Girasol & Hotel de Mar. Privacy & fixed slats 
Coderch never designed mobile frames for residential buildings. When self-criticises for its building in Barceloneta, he speaks about vertical pivoting slats but not sliding. The view of the street or exterior is generally resolved leaving spaces without protection, as in Compositor Bach’s building. For a public building, as a hotel, any mechanism can be tricky. Finally he decides for fixed vertical slats, giving privacy and guiding the views towards the sea. The terraces are oriented to the southeast and the louvers protect the northeast façade, that will slightly receive sunlight. In short façade rooms, southeastern sun penetrates the interior spaces without the protection of the cantilever.
In Girasol building (previous images) large patios open to the front façade have west orientation, and the housing windows try to look the south sun. The openings are generally protected by fixed vertical slats that partially close some gaps, leaving space for the views. These spaces between the lattices leave the glass unprotected, and users have found other types of protection.
Four years before he had already tried the solution in Hotel de Mar (next images).
