Banc Sabadell Headquarters Bach Arquitectes

架构师提供的文本描述。Banc Sabadell的新总部和服务中心是我们在2003年为银行设计和建造的景观办公大楼的改造和扩展。现有建筑物由沿B-30号公路的地块几何形状的纵向办公大楼和一个工业仓库组成，该大楼后面的档案通过四座高架行人天桥连接在底层通道上。该设计建议拆卸现有的工业大厦，将其建筑面积集中在一幢新的写字楼内，腾出位于地块中心的一个大花园表面，成为新总部不同建筑物的入口广场。

Text description provided by the architects. The new headquarters and service centre for Banc Sabadell is conceived as the transformation and extension of the Landscape office complex we designed and built for the bank back in 2003. The existing building is made up of a longitudinal office building block following the geometry of the plot along highway B-30 and an industrial warehouse destined to host the archives behind the building connected to it through four elevated pedestrian footbridges above the ground floor access level. The design proposes to demolish the existing industrial building concentrating its building mass into a new office building, liberating a large garden surface at the centre of the plot which will become the entrance plaza to the different buildings of the new headquarters.

综合大楼的服务水平设在与办公大楼直接相连的中央绿地(礼堂、自助餐厅、人事室、健身房、演讲室、商业区、银行分行、医务室等)之下，而在这一绿地之下，则有两个与现有停车场相连接的楼层。通过这一策略，我们设法彻底改变了这个地方的感觉，把工业区的一栋建筑改造成了一个被花园包围的办公大楼。新办公楼集中在一座小塔上，这一事实不仅使我们能够生成“绿色”区域，而且还为银行今后在下一块土地上扩建大楼以及Banc Sabadell的财产设定了指导方针。

The service level of the complex is placed below this central green area (auditorium, cafeteria, personnel room, gym, lecture rooms, commercial area, bank branch, infirmary, etc) directly connected to the office buildings, and below this one, two parking levels connected to the existing ones. Through this strategy we managed to drastically modify the sense of the place, transforming a building in an industrial area into an office complex surrounded by gardens. The fact that the new office building is concentrated in a small tower allows us not only to generate “green” areas, but also set the guidelines for future building extensions of the bank on the next plot of land, also property of Banc Sabadell.

在解放后的中央空间的西南角，现在是一座新花园，我们建造了一座小型办公大楼，一楼加五层，为萨巴德尔银行(Banco Sabadell)设立了新的方向办公室。在通往停车位的通道坡道上，该街区的悬臂略高一点，显示出它愿意离开中心，提供更多开放空间，使主入口有更大的能见度，并在建筑物和环线之间的地块上显示不同的方向。

At the south west corner of the liberated central space, now a new garden, we raised a small office building block, ground floor plus five, hosting the new direction offices for Banco Sabadell. The block is placed cantilevering slightly above the access ramps to the parking space, demonstrating  its will to shift away from the centre and provide more open space, providing greater visibility to the main entrance and displaying the different orientations in the plot between  buildings and circulations.

办公大楼的设计目的是获得尽可能大的盈利空间，以及最高的通信/服务空间和办公空间比率。为了实现这一点，我们提出了一个非常清晰的结构，一个非中心的中央通信核心提供不同的空间和周边混凝土支柱。外墙是由一个锯齿状的深灰色膨胀金属网格组成，覆盖着由大铝框架包围的开口，为原本非常薄的外墙提供了深度。

The office building is designed to obtain the largest possible profitable space and the highest communication/service space and office space ratio. In order to achieve this we propose a very clear structure, with an off-centre central communication core offering differentiated spaces and  perimeter concrete pillars. The façade is made out of a zigzagging dark grey expanded metal mesh, overlapped by openings enclosed by large aluminium frames providing depth to an otherwise extremely thin façade.

这个立面是一个带有通风室的双层皮肤；锯齿状的金属网使整个建筑物免受太阳辐射的影响，产生了自然通风室，从而提高了建筑物的热性能效率。由于仰角的不同角度会根据太阳辐射的角度而产生不同的细微和阴影，这就增加了这种功能质量的审美品质，从而使他们能够在白天不断地改变自己的面貌。当光线垂直撞击时，立面看上去是一个连续的整体，但当光线开始移动其角度时，立面就变成了不同宽度的垂直板条的组合，与窗户的合理顺序并列。

This façade works as a double skin with a ventilation chamber; the zigzagging metal mesh allows the whole building to be protected from solar radiation generating a natural ventilation chamber that allows for a larger efficiency of the thermal properties of the building. An aesthetic quality is added to this functional quality since the different angles in the elevation generate different subtleties and shadows changing according to the angle of the solar radiation, which allows them to keep changing their aspect along the day. When the light impacts perpendicularly, the elevation looks as a continuous whole, but as the light starts shifting its angle, the façade becomes a combination of vertical slats with different width juxtaposed with the rational order of the windows.

反过来，这些游戏又产生了另一个游戏，它通过非常深的框架，包括折叠百叶窗，增加了非常简单的高度的复杂性，这有助于控制太阳对办公室内部的影响，并向外部提供进一步的转换。窗户的表面深度也使人对室内产生了更大的舒适感，使外墙看起来非常厚实，而它们实际上是非常薄和轻的元素，以增加内部表面。

These ones in turn, generate another play which adds complexity to very simple elevations, through very deep frames including folding shutters that help to control the solar impact towards the interior of the offices and offer further shifting play towards the exterior. The apparent depth of the windows also generate a feeling of greater comfort towards the interior, making the façades look very thick and solid, when they are actually very thin and light elements in order to increase the interior surface.

中央花园下面的水平变成了整个建筑群的功能核心，既有新的办公大楼，也有现有的办公大楼。这是一个平面图，仅超过8.000平方米，位于地下，提供了巨大的空间质量和大量的自然光，使其脱离其地下条件。例如在地面上放置外部出口，在几个战略点上用宽大的露台插入平面图，或在入口楼梯上产生一个双空间，使从地下到外部的视野开放，这些都是为了达到这一目的。

The level right below the central garden is turned into the functional core of the whole complex; both of the new office building as well as the existing one. It is a floor plan barely above 8.000 m2 located below ground floor provided with great spatial quality and a generous amount of natural light liberating it from its underground condition. Strategies such as placing exterior  exits on ground level, puncturing the floor plan with generous patios in a couple of strategic points or generate a double space in the access stairway opening the views from the underground level towards the exterior all aim at achieving this.

这一层次主要集中在礼堂、人事厅、新食堂、健身房、演讲室、银行分行、零售等新综合体的“公共”服务，以及更多的技术房，以利于整个系统的正常运作。所有这些服务都可以通过三种不同的方式获得：主ACES通过位于一楼通往代表性楼梯的入口，或通过ACES层的两个入口进入当前1层的现有办公大楼，将其连接到现有的餐厅层以及该地区的花园和停车场。

This level concentrates most “public” services for the new complex such as the auditorium, personnel room, the new cafeteria, gym, lecture room, bank branch and retail, as well as more technical rooms for the proper operation of the whole. All these services can be accessed through three different ways: The main aces through an entrance located on the ground floor leading to the representative staircase, or through two entrance on the aces level to the existing office building located on current level -1, connecting it to the existing restaurant level and the garden and parking zones of this area.

在原先与直通式办公大楼相连的工业仓库里，我们建造了一个大型花园广场，目的是成为新总部的中心。这个花园不仅是一个放松的空间，也是一个露天活动，或者只是一个视觉空间，供办公室观看，而且也是通往办公室的入口。它是联系整个复杂的循环空间和关系空间。

In the area previously occupied by the industrial warehouse linked to the lineal office building, we built a large garden plaza which aims at becoming the heart of the new headquarters. This garden works not only as a relaxation space, but also as open-air activities or simply as a visual space where offices look into, but also as the access point to the offices. It is the circulation and relation space articulating the whole complex.

为了达到这个目标，我们修改了现有桥梁的用途，使它们从原来的“自动售货”和会议功能转变为现有建筑物的新入口点。这些桥梁以前把办公室和底层的工业仓库连接起来，现在它们成为新花园的入口和会议室。在建筑上，桥梁已经稍微延伸到花园，并提供了一个宏伟的入口办公室，通过一个小门廊结合楼梯的-2和-3停车场。这样，你就可以通过汽车进入建筑群，并从地下的楼梯上爬起来，一直躲在屋顶上，直到选定的入口。

In order to achieve this goal, we modified the use of the existing bridges turning them from their former “vending” and meeting functions to become new entrance  spots to the existing building. These bridges previously linked the offices with the industrial warehouse in the ground floor level, while they now become entrance point and meeting rooms from the new gardens. Construction wise, bridges have been slightly extended to reach the garden and provide a grand entrance to the offices, through a small porch integrating the staircases of the -2 and -3 parking levels. This way one can access the complex by car and rise through the staircases from the underground, always sheltered by a roof, until the chosen entrance.
