Concrete wall

The term “conventional” is really poor when we refer it to such an exceptional façade; however, and attending the taxonomical criteria we are using in this platform: the material form of the façade supporting elements is amorphous, and the watertightness mechanism is by material barrier.
This example permits us showing how wide is the meaning of each one of the taxons used in our classification, and how poor the common solutions that have helped us to illustrate them.


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. 


This project is called Isarhof, wich means in german “the yards of Isar”, as a reference to those empty spaces trhough the school, and at the same time, the proximity to the Isar river. I wanted to implement a three-yard systemdifferentiated, where the urban life is developed and at the same time the day to day of the students. These gaps generated by the building itself and the elimination of some pre-existing ones, generate separate interstitial spaces.

The MACBA, the Film-Library, and now the new Massana school building: all of them big public buildings to be inserted into a dense, small-grain urban structure. In the case of the Massana school, the strategy is to decompose the volume into two bodies that do not even seem to be part of the same building - justifying the great hall. Each one of these bodies is at the same time composed from a series of prisms generating terraces and cantilevers over the square, in the case of the one that configures the main facade.

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.

We distrust the effectiveness that the ceramic baguettes may have as sunscreen, valuing however the richness in lights and shadows that they generate. The smooth and cold surface of a glazed envelope adopts a much more Mediterranean image when having an umbraculum over it. Sky reflections, brightness and shadows.

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.
