In the heart of Palma de Mallorca, a distinctive 1940s rationalist building, originally designed by Mallorcan architect Francisco Casas, is entering a new chapter through a carefully considered restoration and extension project.
Designed by the renowned architectural practice García-Ruiz Arquitectos and undertaken by Construcciones Llull Sastre, the project began in 2026 with the aim of preserving the building’s original architectural identity while introducing contemporary elements that complement its historic character.

Architectural restoration: preserving the past, shaping the future
The design respects the building’s original lines and rationalist character, an architectural movement defined by geometric clarity, functionality and understated elegance.
García-Ruiz Arquitectos introduces carefully positioned setback volumes, vertical architectural elements and precisely defined shadow lines, creating a refined dialogue between the existing structure and the contemporary intervention.
The result is an architectural approach that brings heritage and modern design together, preserving the essence of the original building while allowing it to evolve.
