The comprehensive refurbishment of the rear façade of Antoni Gaudí’s work and the private courtyard of the Planta Noble required an investment of 3.5 million euros and the joint work of specialised restorers and local craftsmen who have preserved centuries-old techniques and adapted them to contemporary standards.
This intervention marks a historic milestone, as since 1915 the colours of the rear façade had changed and characteristic elements of the courtyard such as the jardinières and the pergola had completely disappeared. Although there was limited restoration work in the 1950s and 1990s, this represents the first truly comprehensive restoration of the space, where every material has been returned to its original splendour in accordance with Gaudí’s intentions.
The restoration process has revealed surprising discoveries that have completely transformed the understanding of the original design. Xavier Villanueva, the architect in charge of the operation, said that when they found the original colours they were astonished, as the façade had become the photographic negative of the original designed by Gaudí. Stratigraphic tests carried out during the pandemic revealed the original shades hidden under layers of paint on the wood, ironwork and stucco.
The rebirth of an intimate space designed by the modernista genius
The restoration has brought back to life the intimate outdoor space next to the dining room, originally conceived as a garden-like retreat for family relaxation. On the rear façade, the stucco and glass and ceramic trencadís of the side walls and cornice have been restored, while the wrought iron railings, wooden windows, balcony doors and mosaic paving have been recovered on the balconies, reinforcing a structure that was in a state of extreme deterioration.
The private courtyard has undergone an even more spectacular transformation with the reproduction of elements lost in time. The heather pergola with a parabolic shape that was originally located in the centre of the courtyard has been recreated, together with the planters located next to the ventilation courtyards. The paving has been faithfully replicated using 85,000 pieces of Nolla mosaic, respecting the original techniques.
This restoration is part of a five-year series of major interventions that culminates in 2025, the year in which Casa Batlló commemorates the 20th anniversary of its inscription as a UNESCO World Heritage Site. Gary Gautier, CEO of Casa Batlló, believes that being part of this milestone represents a true honour, uncovering Gaudí’s genius for future generations and celebrating the enduring craftsmanship of master artisans, a gift not only to Barcelona, but to the world.
Rigorous research combined with advanced digital techniques such as 3D scanning and photogrammetry has ensured pinpoint accuracy in the restoration. Among the most outstanding findings is a previously unknown structure in the form of a spiral of brick and mixed iron, as well as a newly discovered vaulted system supporting the balconies, representing a revolutionary innovation for its time that reinforces Gaudí’s constructive genius.
