Casa Mila

Title

Casa Milà (La Pedrera, "the stone quarry")

Date

1906–1912

Materials

limestone blocks (façade), cast iron, brick (parabolic attic vaults), wrought iron (balconies, designed by Jujol), tile, plaster.

Theme

Organic / structural modernism — a residential building that pushes the boundary between architecture, landscape, and sculpture.

fascade

Undulating rough-cut limestone blocks with unequal windows of varying size (maximizing natural light per floor). Twisting iron balconies

plan

Two asymmetric courtyards in a figure-8 layout, providing light to all nine stories. The main floor (1,323 m²) was the Milà family residence.

attic

270 parabolic brick vaults of varying heights forming a ribcage-like undulating space, originally a laundry. Acts as a thermal insulator for the roof.

rooftop

Sculptural chimneys (grouped, snail-shaped water tanks), six staircase exits covered in broken pottery, two ventilation domes — all functional but visually monumental.

underground garage

An innovative basement parking level for automobiles — a concept so forward-thinking that contemporaries found it incomprehensible

Style

Catalan Modernisme — Gaudí's most structurally radical work. Anticipates modern architecture with its free-plan principle.

Composition & structural innovation

The façade is self-supporting (load-bearing walls eliminated) — connected to each floor's structure via curved iron perimeter beams. This free-plan layout means every interior wall can be removed without affecting the building's stability — a radically modern concept in 1906.

light

Light is maximized through unequal window openings and the two open courtyard shafts.

context

Gaudí's last private residential building. The structure exceeded the legally permitted building footprint, forcing the Milà family to pay a fine to the city — a sign of how little Gaudí respected conventional urban regulations when he believed his design was superior

Commissioned by

 Pere Milà

meaning of the work

represents the fullest expression of Gaudí's structural and spatial thinking: a building that looks organic but is built on rigorous geometric logic (parabolic arches, ruled surfaces). The underground garage reflects Gaudí's visionary belief that automobiles would transform urban life — decades before most architects acknowledged it. The free-plan floor system and self-supporting façade directly anticipate key principles of 20th-century modern architecture.
