Concrete wall

The façade of San Telmo museum manages to extract all the design potential from the succession of layers. The surprising thing in this case is that the architects are not limited to the façade layers but, in their proposal, they consider as layers the different planes that follow one another when making a transversal cut to the building. They get that the built volume and its limits - façade and mountain- merge.

In this building of Stump & Schibli Architekten we want to highlight the wisdom to solve the blind area with continuous horizontal stripes along the different facades, while the openings treatment is adapted to the different conditions between the courtyard facades and the more urban ones. 

Batlle and Roig designed a double skin façade for this office building in 22@. The interior layer meets the thermal requirements as well as air and water tightness, while the exterior one delimits the building volumetrically and seeks to improve its thermal behavior.

It is difficult to understand the need of building this thick, load bearing, cast in-situ concrete wall hidden behind a light cladding made of different layers: mineral wool; coloured ribbed plates; glass slats. In the inside, the concrete wall is again hidden, in this occasion by furniture. The climbing formwork system that made possible this wall had to be successively cut so as to be adapted to the changes on the diameter and curvature of the tower. Not less must have been the difficulty when preparing the reinforcement.
