The Colegio Maravillas Gymnasium, designed by Alejandro de la Sota, is an exemplary model of modern Spanish architecture. Its steel structure stands out for its trusses, supporting learning spaces and a thick roof that covers a vast recreational area for students. In Mark Pimlott’s terms, the gymnasium can be understood as a «shed», a minimal and open structure that is more about enabling activity than representing form. The shed roof, supported by clear and rational trusses, creates an expansive, unpretentious interior that is generous in both scale and spirit, fostering collective experience and social interaction. De la Sota prioritizes the system over form, creating flexible spaces that serve as a framework for the daily lives of students and teachers while also opening up to the local community. His approach, both technocratic and humanistic, is reflected in functional solutions and a strong structural clarity. Far from being purely technical architecture, the gymnasium illustrates De la Sota’s desire to balance rigor with sensitivity. The interaction between natural light, raw materials, and warm textures gives the building a welcoming and vibrant atmosphere, fostering social connections within the school and with the local community.
