Emporis Skyscraper Award 2010 Know more +

Its organic shape, inspired by nature,
changes and opens up like a flower.

A 28-floor tower with a height of 112.71 meters and a surface area of 34,688 m², an architectural and facade engineering challenge.

This skyscraper is an iconic feature of Barcelona, a work by the Japanese architect Toyo Ito, the winner of the 2010 Emporis Skyscraper Award.

Double Skin with a
flexible tube system

We installed the Double Skin on a reinforced concrete structure with different floors. The inner skin features a curtain wall system, while the outer skin incorporates diagonal red metal tubes that adapt to the tower’s geometry. A total of 16,056 tubes of varying lengths add movement to the building and create different perspectives depending on the point of view.

An integral facade project

MCM managed all the phases of the facade project: global design, construction details, structural calculations, samples, tests, manufacturing drawings, layout and assembly. We also provided certificates and warranties for all materials. The engineering was completed in two months, and the construction work was executed very efficiently, finishing in ten months.
