Date

Artist

Antoni Gaudi

Location

Barcelona

Theme

Organic / naturalistic architecture with religious and legendary symbolism

Lower façade

Montjuïc stone ground floor with sinuous tracery; six thin bone-like columns with floral-joint decorations; skull-shaped balconies. Nicknamed "House of Bones" (Casa dels Ossos).

Central façade

Undulating surface of broken ceramic discs and glass in blues and greens, evoking water and Monet's water lilies.

Roof

Arched dragon-back tiles in polychrome ceramics, a cross-topped tower with JHS/M/JHP monograms, and four anti-backdraft chimneys.

Interior loft

Series of 60 catenary arches in white — resembling the ribcage of the dragon whose spine appears on the roof.

courtyard enlargement

given a gradation of tile colors (deep blue at the bottom fading to white at the top) to ensure uniform light distribution on all floors.

Style

Catalan Modernisme — Gaudí's mature organic phase. No straight lines anywhere in the building.

Composition & space

the façade is divided into three harmonious vertical zones (lower / central / crown). The interior is organized around an enlarged central courtyard that acts as a light shaft. The loft forms a transitional space between apartments and roof.

Color & light

ceramic mosaic on the façade transitions from golden-orange at the bottom to greenish-blue at the top. The courtyard uses a deliberate gradient of ceramic tile shades to counterbalance natural light intensity — a scientific approach to uniform illumination across all floors.

commissioned by

Josep Batlló, who wanted a unique residence unlike any in Barcelona. Rather than demolish the existing 1877 building, Gaudí — conscious of waste — renovated the façade, expanded the courtyard, and redesigned all interiors.

meaning

visual retelling of the legend of Saint George (patron of Catalonia) slaying the dragon: the roof is the dragon's back, the tower is his lance, the bone-like columns are the victims' remains. It also demonstrates Gaudí's belief that architecture should eliminate straight lines
