这个外立面改造项目的业主是墨西哥最大的奢侈品零售商。其全新的形象背后是一套简单有效的建筑系统，从生产到装备，安装都很有效率。最后的外形结果也相当有趣。

这里是热带气候，太阳强烈湿度也高。因此从耐久和扛老化等因素选择了混凝土作为外立面的主材。设计过程对混凝土的潜力和性能进行了研究，比如复杂的几何形以及不同的配比和浇筑方法。

最后采用5种不同类型的螺旋桨般的预制件，按轴线旋转180度，根据位置安装在16米或20米的位置。简单的控制和变化创造出一个动感整体，其独特的外观给街道上车行和步行的人深刻印象。白天日光阴影变化相当丰富，夜晚又是变幻的人工照明。这里总是在改变，这里从不静止。

FAÇADE DESIGN BY IÑAKI ECHEVERRIA NOW OPEN

The aim was to design a dynamic and modern façade that would provide a new image for the largest luxury retailer in Mexico.

Tuesday March 27th 2012, Villahermosa, Tabasco. Accompanied by Store Director, Max David, State Governor Andrés Granier Melo, led the opening ceremony of the new Liverpool Altabrisa in Tabasco. Located in a strategic area on the south end of the city, the shopping center Plaza Altabrisa is part of a new development pole for Villahermosa.

The project’s challenge was to find a simple and effective construction system that would accelerate the production, assembly, and installation of the façade and, at the same time, provide a complex and interesting proposal.

Given Tabasco’s tropical climate and its severe solar incidence and humidity levels, concrete was selected as the project’s design material; a material both resistant and with extraordinary aging qualities. With the development of innovative construction technologies, the project would seek a new image for Liverpool.  The solution emerged from a research and development process, where the concrete’s potential and ability to form complex geometries was explored. On the other hand, extensive trial and error processes were applied involving different pouring methods and formwork materials, such as, fiberglass, concrete and sand.

The result was a façade that’s built by combining 5 different types of precast pieces shaped like a propeller. Each propeller rotates 180° on its axis; heights vary between 16 to 20 meters, depending on their position.

These simple and controlled variations create numerous results for each piece, which as a whole, give a sense of movement; this effect is better appreciated at a distance and when passing trough by car at high speed. From up close, the concrete looks like a fine wood; the acid layer applied as a final coating, brings out the concrete’s grain, which in return, gives the material this odd appearance.

Additionally, the light changes that occur during the day, and the artificial lighting at night, provide an interesting mixture of colors, reflections and shadows, achieving an always changing and never static image for the façade.
