The building was nicknamed 'La Pedrera' (The Stone Quarry) by locals during construction due to its resemblance to an open-pit mine.
The facade contains no straight lines, requiring custom-fitted glass windows for every individual window frame.
The structural load of the building is carried by a skeleton of steel columns, a pioneering technique for its time.
The design includes an underground parking garage, which was the first of its kind in a private residential building in Barcelona.
The rooftop chimneys were designed with aerodynamic shapes to facilitate proper ventilation of the building's interior.
Gaudí intended to place a massive sculpture of the Virgin Mary on the roof, but the project was cancelled following the Tragic Week uprising.
The iron balconies were crafted by Josep Maria Jujol and feature organic, wrought-iron shapes resembling dried seaweed.
The building utilizes two large interior courtyards designed to provide natural light and cross-ventilation to all apartments.
La Pedrera, officially Casa Milà, is the final private residence designed by Antoni Gaudí, constructed between 1906 and 1912. The building is renowned for its self-supporting stone facade and undulating, irregular floor plan that lacks load-bearing walls. Its roof terrace is a sculptural landscape featuring ventilation towers and chimneys finished in broken ceramic shards, or trencadís. The attic floor, known as the Whale Attic, contains a structural system of 270 parabolic brick arches. Inside, the building hosts the Fundació Catalunya La Pedrera, which manages exhibitions and cultural programming. The residence is a UNESCO World Heritage site representing the pinnacle of Catalan Modernisme architecture. Visitors access the rooftop, the attic exhibition, and a period-furnished apartment floor.
