In 1943, the engineer Luis Tolosa built a reinforced concrete structure in the port of Donostia-San Sebastián following the logic of Modern Movement of Architecture. An austere pavilion, barely a large roof, to store the wooden boxes used by the fishing fleet. The large roof in turn, served as platform for repairing, cleaning and drying of fishing nets. This large roof, which flies getting thinner than the load-bearing structure with its beams and pillars, was undoubtedly the most representative element of the building, which made the building popularly known as the Aircraft Carrier.
▼原始建筑，the original building
In 1988, the project underwent a total transformation, using the old structure as support for the building, which would close off the old roof by adding facades and generating diverse interior spaces.

The project completed in 2019, is conceived nearly as an archaeological exercise that seeks to remove, eliminate those parts that blurred the original project, returning as far as possible the protagonism of the building to the original structure and its large roof. In order to organize the programme proposed in the competition, a set of volumes is placed in the shelter of the roof, which establishes an echo with the stacked wooden boxes that initially occupied that place, in a fragmented way. In this sense, the project can be summed up as the addition of two actions, on one hand for cleaning, clarifying and on the other hand for the construction of closures and new façades.

▼拥有全新立面的建筑与周围环境和谐相融，with a new facade, the building blends in with its surroundings
These new facades are conceived as continuity with the logic of place and context, but from a clearly contemporary point of view. In this sense, on one hand ceramic is used, as material widely used in the facades of fishermen’s houses that face the city’s harbor, due to its capacity to withstand saltpeter and the harshness of the Cantabrian Sea. On the other hand, white colour is used, as an iconic colour represented in Royal Yacht Club, built just 100 meters away, and perhaps the most emblematic work of Modern Movement built in Spain.

Ceramic is treated here as a three-dimensional piece, which vibrates in six subtly different whites, some of them matt finished and others glossy finished. On the one hand, is established this relationship with these two close architectures, represented in the context of the port of the city, the popular one and the enlightened one. On the other hand, is pursued a phenomenological effect that makes the façade function as an independent element of the original roof and structure.

建筑外部结构的包覆层旨在使该建筑与码头建筑群融为一体，并与水面上不断变换的光影相呼应。为了达到这个目的，项目团队采用了带有浮雕的陶瓷片。陶瓷片为18cm × 40cm的固定尺寸，带有三角形浮雕，可以放置在包括拐角在内的任何位置。并且，陶瓷块在组装中也无需进行再次切割，仅按照行与列的顺序就能完成立面上的画布和开口。

By means of this simple mechanism of the asymmetrical triangle, variability is introduced that allows the individual comprehension of each one of the pieces. Unit and set similar to that of the wooden boxes stacked there. In addition, the movement of the sun, changes in light and seasons, as well as the reflection of rain, give the façade a changing appearance. It is full of shades and gleams, as the surface of the sea, face to which the building stands.
In this sense, the cladding of the enclosure aims to integrate the building with the buildings of the quay, and to participate in the changing reflections of water and light. For this purpose, it is considered appropriate to use ceramic pieces with relief, by means of an own design for the Lonja building. The ceramic pieces, of fixed size 18cm x 40cm in elevation, and with triangular relief, allow their placement in turned position, and they are organized in rows and columns, to be able to complete the canvases and openings in facade without needing to fracture any of them for its assembly in work.

立面围护在满足一些需要大量室外照明的空间的同时，也要保证其他区域的私密性。而通过引入固定尺寸为6cm x 6cm x 40cm的空心矩形组件便可以使问题得以解决。这些零件被设置在可调整间距的不锈钢支架上，从而保证了建筑的整体性和材料的连续性。
The enclosure has also areas that require more outdoor lighting, but combined with others with some privacy inside. This is solved with the incorporation of pieces of vertical lattices, a hollow rectangular piece of fixed dimension 6cm x 6cm x 40cm. These pieces are set on a stainless steel support with variable separation, which gives to the whole an idea of unity and material continuity.
