Casa Milà — known affectionately as La Pedrera (the quarry) — is Gaudí’s manifesto for urban living. Commissioned by Pere Milà i Camps and Roser Segimon (1906–1912), it reimagines the apartment block as a breathing organism with undulating stone, iron balconies like seaweed, and light wells that pour daylight to the deepest floors.

Why It Matters
- Breaks from flat façades: the stone becomes topography.
- Prioritizes air, light, and circulation through twin courtyards and continuous ramps.
- Synthesizes structure + ornament so they act as one system.
“The straight line belongs to men, the curved one to God.” — often attributed to Gaudí
Anatomy of a Living Building
- Façade: limestone waves, no strict symmetry, ironwork balconies like kelp in a current.
- Courtyards: two light wells as lungs; chromatic plaster amplifies light.
- Rooftop: chimneys as guardians, stair drums as spiral shells, a skyline theatre.
