It is a great pleasure to share this amazing example of good architecture with all Facad3s followers. There is no formal boasting, no latest generation materials, no added gadgets for energy production, no raw land or straw. The building manages to be attractive by being clever, and sustainable by being reasonable. 

Very narrow and large cladding pieces fixed longitudinally. The large number of horizontal profiles needed is increased by the fact that the lattice plates do not share the fixing profiles each two, as in the blind area. Therefore, the need of profiles is practically doubled in these parts of the facade.

A very correct but expensive solution.

Unlike what stone, pressed ceramic tiles, or any kind of artificial panels -board type-, can give, extruded terracotta elements can, due to the manufacturing process, easily be three-dimensional!!! A possibility which architects not always take advantage of, even though terracotta is a common material in façade claddings. 

And pay attention to these difficult corners where three-dimensional elements may exhibit their hollowness!!

Although prefabricated concrete panels incorporating stone claddings are not something new -as an example to highlight the Hotel in Plaza España, designed by the architect Enric Garces, and built in 1990-; we want to draw attention on the appropriateness of the solution today.

As we mentioned in the wake of the SBG Schönburg building in Bern, the open-joint claddings are in crisis -not because of their performance, which nobody questions, but merely due to formal reasons.

Rain screen facades solved with thin claddings are a good solution regarding watertightness and the sun radiation protection. Besides that, they permit a wide range of image variations and so are supposed to be a gift for most of the architects. However, for some of them, all those open joint claddings give somehow a sense of lack of robustness; the wall is just a veneer, a vail. 

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.

Sober architecture but a confusing solution.

In this concrete façade: which is the main façade layer? The concrete panel 8 cm thick, or the brick wall? 

The relationship between the facade enclosure and the structure is a recurring theme in Batlle and Roig work.  While in the CMT headquarters building the structure is located offset from the facade, allowing the free development of a nearly entirely glazed envelope; in the office building on 22@ the structure is placed on the facade.

A group of residential buildings in Torrelago district, Laguna de Duero (Valladolid), has been refurbished in the context of the European Programme CITyFIED: Replicable and Innovative Future Efficient Districts and Cities. The renovation addresses both the image of the buildings and energy factors. 

Little to say about such a glass facade. A steel-profiles mesh covering like a blanket the everyday life.
