The proposal takes advantage of the periurban character of the site and the natural slope of the terrain to fragment the building into three volumes, freeing up space for a new public square that acts as a scenic lookout towards Tiana’s historic centre and the church of Sant Cebrià. This elevated plaza becomes the heart of a network of green paths and platforms, linking the Dioptria Space with the Camí Mig d’Alella and forming a linear park down to the stream. The strategy enhances natural ventilation, sunlight, and air quality across the site. A new urban square is proposed at the entrance of the existing facility—partially sunken into the terrain—framed by deciduous trees and shrubs that offer seasonal comfort and reinforce its civic character.
