Casa Batllo, Gaudi’s living façade on Passeig de Gràcia

Casa Batllo in Barcelona is a townhouse transformed by Antoni Gaudi into a flowing façade of colour and sculpted surfaces along Passeig de Gràcia in the Eixample district. Built in the late nineteenth century and reimagined between 1904 and 1906, it stands today as one of Gaudi’s key works and forms part of the UNESCO-listed ensemble of his architecture in Catalonia.

When textile industrialist Josep Batlló i Casanovas acquired the property in 1903, he commissioned Gaudi to undertake a complete renovation rather than demolishing and rebuilding, giving the architect scope to rethink the façade, interiors and roofline.commissioned Gaudi in 1903 Between 1904 and 1906, the townhouse gained its undulating street front, expressive balconies and sculpted attic and roof, turning an earlier, austere structure into one of the clearest statements of Catalan modernism on the avenue.1904–1906 renovation

Gaudi’s mature modernism in stone, ceramics and glass

The façade of Casa Batllo is a study in surface and colour, with a masonry base, projecting balconies and upper levels clad in a mosaic of ceramic and glass pieces that catch the light along Passeig de Gràcia.a marvel of ornamental design The way the floors are expressed gives the impression of a continuous, rippling skin across the front of the house, contrasting with the more rectilinear neighbours on the Block of Discord.
