From the 1980s onwards, Bastidas devoted himself to architecture, especially in the Balearic Islands and realized concepts of buildings, especially from the 18th century, for their ecologically modern use while preserving the original character as much as possible.

[7] In 2017, donations from the French Marathon des Sables foundation MDS Solidarité and Bastidas made it possible to completely renovate and expand the school with materials and components that are mostly locally sourced.

At the same time, it was ensured that the high climatic requirements for classrooms, dormitories and staff rooms in the mountainous region were met and that the kitchen and sanitary facilities functioned perfectly at outside temperatures of up to -20°C.

[8] Due to his careful handling of historical buildings, the surrounding gardens and parks Sergi Bastidas was honored with the Rafael Manzano Prize for New Traditional Architecture donated by Richard H. Driehaus in 2021.

The presentation of the most prestigious architecture prize awarded on the Iberian Peninsula took place in Madrid at the Royal Academy of Fine Arts of San Fernando.
