Comprehensive rehabilitation of a building located in 81 Atocha Street turning this building into a 4* Hotel. Grupo Carinbisa replaced all exterior wood carpentry. The exterior windows were refurbished with new ones respecting the integral global protection (keeping the original typologies, colours and materials), and incorporating new furniture with inherent thermal insulation and acoustic qualities required for the greatest comfort in the new use of the building, especially on the main façade of Atocha Street.
