在这座伊东丰雄和b720建筑事务所Fermln Vazquez的作品背后，是对环境的即刻反应以及从El Prat国际机场出来通往L’Hospitalet de Llobregat 和巴塞罗那的门户。
The key priorities behind this architectural project by Toyo Ito and b720 Arquitectos, headed by Fermln Vazquez, are to respond to the immediate environment and serve as a gateway to the cities of L’Hospitalet de Llobregat and Barcelona from El Prat International Airport.

项目包括两个相互对比的高楼，他们互相形成一种微妙的对话。景观两座大楼在外形方面对比清晰明确，但两者的关系依然是是和谐互补的。这两座建筑（都是110米高），都有高度的象征意义，他们站在巴塞罗那的西班牙广场展览中心的入口，向历史建筑威尼斯塔致敬。
The project consists of two differentiated towers that engage in a subtle dialogue. Despite the clear contrast between the buildings in terms of form, the relationship they establish is harmonious and complementary. The buildings (each 110 m high) play a highly symbolic role as they pay tribute to the historical Venetian towers that stand at the entrance to the exhibition centre located near Plaza Espana in Barcelona.

多变几何形
酒店大楼才用有机形式设计，外形随着观察角度不同而改变。外立面被分割成两层以显示建筑的机和复杂性，内层如同被信封封住一般被铝制光幕墙和玻璃面板包裹，以达到相应的声，热，密封要求。外层是第二层皮肤的作用，提供纹理和大楼的集合可变形状。这层面板有独立铝管，其尾部连接球窝关节，使得一些必要的扭转变得可能。
Variable geometry
The hotel tower (GF+25)* was designed with an organic form and appears to change as one moves around it. Given the building’s geometrical complexity, the façade is divided into two skins. The inner skin is a sealed envelope based on a light curtain-wall solution with aluminium and glass panels designed to fully meet all acoustic, thermal and sealing requirements. The exterior façade acts as a second skin that provides texture and accommodates the tower’s variable geometry. The skin is made of independent aluminium tubes whose ends are attached to ball-and-socket joints that allow for the desired torsion.

球窝关节，铝管，以及支撑结构的关系在于允许整个表面呈现缓慢持续的的改变，在大楼直立的状态下表达旋转，移动以及成长。大楼在三分之一处被分隔。下面三分之二部分的几何结构是根据多变的旋转和位移形成，上面三分之一部分，对底平面进行了变形和缩放，放大了大楼的表面积和周长。
The relationship between the ball-and-socket joints, the aluminium tubes, and the supporting structure is what allows the entire surface of the façade to gradually and continuously adapt, expressing rotation, movement and growth as the tower rises upwards. The tower is divided into three thirds. The geometry of the lower two thirds is based on variable rotation and displacement, whereas in the upper third, the ground plan is deformed and scaled up to increase the surface area and perimeter of the tower.

办公楼
办公楼跟欧罗巴广场正交垂直，标明了广场尽头，作为相接的两座建筑对称地分布在Gran Vía的另一侧。（两座垂直于中轴线的相互正交的高楼）这更加明显的让人们看见，当大楼主体和外立面接触时，他被欧罗巴广场中轴线这一无形的垂直平面切断。
Office building
The office building (GF+22)* – orthogonal in form and positioned perpendicular to the central axis of Plaza Europa (at 30o to Gran Vía) – marks the end of the plaza and engages in a dialogue with the bordering structures symmetrically located on the other side of Gran Vía (two orthogonal towers perpendicular to the axis). This is even more apparent when one sees that when the core of the office building reaches the façade it is cut by an invisible vertical plane that is aligned with the central axis of Plaza Europa.

办公楼对扭曲运动的酒店是一种感知上的回应和补充。第一眼看上去像一个纯粹的玻璃幕墙为背景的空间，楼板稍稍向后。然而红色的楼体核心在平面的边缘，是有机形状的，而且反映出酒店建筑的结构。这两座高楼由一个公用的中庭连接。一个大底连接“双塔”，并放大对两座建筑的结构的影响。
The office tower complements and responds to the perceived twisting and movement of the hotel building. At first glance it appears to be a pure volume with a glass curtain wall set back slightly with respect to the floor slab. However, the red vertical core of the building, situated on the edge of the ground plan, is organic in form and reflects the structure of the hotel tower. The two towers are also linked by a shared atrium. A large base joins the towers and amplifies the impact of their structure.

建筑与众不同的外形，结合110米的高度，还有80108平方米的表面积，使这个建筑成为新欧罗巴广场，L’Hospitalet de Llobregat和巴塞罗那天际线上的里程碑和有力一笔。
The unique look of the buildings, combined with their 110 m height and a total built surface area of 80,108 m2, makes the project a milestone for the new Plaza Europa and the city of L’Hospitalet de Llobregat, and a clear reference point on the Barcelona skyline.
