Casa Mila Roof

The rooftop of La Pedrera – The Casa Milà building in Barcelona, Spain, is a masterpiece designed by the visionary architect Antoni Gaudí.

This rooftop is a standout feature of the building, showcasing Gaudí’s innovative architectural style. 

The terrace serves a functional purpose and adds a decorative and visually appealing element to Casa Milà. 

Gaudí’s rooftop design emphasizes natural light and direct ventilation throughout the building.

He created a unique and harmonious architectural masterpiece that breaks away from the traditional styles of the time. 

Its self-supporting stone facade, free-plan floor, underground garage, and spectacular roof terrace contribute to Casa Mila’s fame and architectural significance.

Another distinctive feature of this unusual roof is the interior courtyard perimeter fence, which often catches visitors’ attention due to its mismatch with the building’s uniformity.

This article highlights key features and details of the roof terrace at Casa Milà.

The Roof Terrace at La Pedrera-Casa Milà

La Pedrera-Casa Milà has a distinctive rooftop terrace.

It feels like a museum filled with Gaudí-style sculptures when you walk around it.

The construction features on the roof, such as the chimneys, ventilation towers, and attic access staircases, combine excellent functionality with aesthetic quality and order.

The ventilation towers help circulate air in the attic.

Gaudí also used curves to soften the volumes of the staircases.

These curves are all derived from regulated geometry, which uses concavity, convexity, and conical shapes to lighten the building.

The roof terrace has stairwells covered in monochromatic ceramic trencadís mosaic, recycled stone, or marble. 

There are two groups of three and four chimneys (smoke outlets).

Gaudí turns them on their own, using an internal and external layout that mimics the aerodynamic movement of the smoke to give them their sculptural shapes.

In the original version of trencadís, a group of chimneys is covered in pieces of cava bottles. 

The Fences of the Rooftop

On this unusual roof, one feature often overlooked by guests is a perimeter fence that breaks the building’s curving shape.

Gaudí failed to complete the model he started for the roof railing, as seen in the 1909 photo.

The proprietors put up a fence made of hexagonal mesh as protection against the risk of leaving the area without supervision.

Previously, the roof served as a service area for chimney smoke flues and, occasionally, as a place to hang clothes. This was not the conventional use of the roof.

Gaudí created the roof with form, function, and aesthetics in mind.

Still, he could not complete some of the roof elements’ external protection and decoration because of financial difficulties with the owners.

Every element, whether it be the stucco or trencadís, the Gaudinian or just simple protective fences, is a part of the building’s construction history, adding to its uniqueness and vitality.

Restoration of Casa Mila rooftop

A restoration process was carried out to restore Casa Milà’s rooftop to its former splendor.

To restore the space, elements that had been added after Gaudí’s time had to be removed, including additional chimneys.

The chimneys were repaired using pieces of glass, and tile fragments were used to restore the Ulldecona stone overhangs.
