架构师提供的文本描述。这个项目是为了重新开发Koblenz的主广场-“Zentry alplatz”而开始的。该方案包括约20 000平方米的零售空间、更多的文化和旅游空间以及6.000平方米的城市广场。

完整的程序被分成两个卷，中间有Zentry alplatz。功能分离允许两个自主和高功能的建筑物，它们可以长期独立地发展。这两座建筑和广场形成了一个城市整体。由于建筑物的精确定位和轮廓，使中央广场成为公共环境的人流以有效和合乎逻辑的方式组织起来。这两座建筑在城市和建筑的实施上是相互补充和加强的。

The complete program is split into two volumes, with the Zentralplatz in between. The separation of functions allows for two autonomous and highly functional buildings, which can develop long-term and independently. The two buildings and the square create an urban ensemble. Because of the precise positioning of the buildings and their outline, the pedestrian flows, which make the central square a public setting, are organized in an effective and logical way. The two buildings are complemented and strengthened in their urban and architectural implementation by each other’s background.

库尔图托藏有公共图书馆、米塔尔谢林博物馆和科布伦茨的旅游信息。这些不同文化机构的结合提供了利用各机构之间协同作用的机会。

The Kulturbau houses the public library, the Mittelrhein Museum and the tourist information of Koblenz. The combination of these different cultural institutions offers the chance to exploit the synergies between the various institutions.

这座文化建筑孤立地矗立在新的中央广场上。它的轮廓是自然创造的定位在“流”的路线。在开放的广场上，这三个功能都有自己的接入和发展，从那里垂直层。室内不少于30米高的空间连接着各机构，营造了一种轻快、通风的氛围，提供了良好的定位。这座建筑有极好的无障碍环境；中央大厅有四面八方的入口，因此是城市结构的一个自然部分。

The cultural building stands solitary in the new central square. Its outline is created naturally by the positioning in the "flow" of routes. On the open square, the three functions each have their own access and develop from there in vertical layers. The no less than 30 meters high space inside connects the institutions, creates a light and airy atmosphere and offers good orientation. The building has splendid accessibility; the central lobby has entrances from all sides and is therefore a natural part of the urban fabric.

该卷有一个双层外墙，结构打印的主题提供了一个从内部到外部的过滤视图，并允许在从外部进入时有一个模糊的视图。在不同的入口，外立面有一个宽敞的剪裁，因此可以直接看到大厅和入口区域。

The volume has an double façade with a Structural-Glazing construction of white silk-screened glass, which embraces the building like a second skin. The motif of the print provides a filtered view from inside to outside and allows a vague view when looking from the outside in. At the different entrances, the outer façade has a spacious cut and therefore offers a direct view of the lobby and entrance areas.

商场论坛米塔尔谢林呈现出自己作为一个平面，水平分层的结构。由于这种强大的格式，有效地减少了建筑体积，并建立了愉快的规模感。

The mall Forum Mittelrhein presents itself as a flat, horizontal layered structure. Due to this powerful format, the buildings volume is reduced efficiently and a pleasant sense of scale is established.

在城市结构内的相关路口，购物中心提供宽敞的入口，并邀请游客跟随行人流动，并在大楼内“滑行”。购物中心的特点是其梯形的布局和平滑的轮廓。与自动扶梯交织在一起的区域提供了定位点，分隔了建筑物，并为内部提供了自然光。这结合了巨大的空间，给用户提供了高水平的舒适和愉快的氛围。通过强烈的颜色的空白边缘，强大的重音，创造了一个生动的形象。

On relevant junctions within the urban fabric, the mall offers spacious entrances and invites visitors to follow the pedestrian flows and to ‘glide’ through the building. The shopping center is characterized by its trapezoidal layout and smooth outlines. The areas intertwined with escalators provide orientation points, divide the building and provide the interior with natural light. This, in combination with the great spaciousness, gives a high-level of amenity and a pleasant ambience for the user. Across the intense colors of the void edges, powerful accentuations are applied that create a vivid image.

销售楼层位于-1、0和1层。在地下室，装卸区的组织方式可以方便地协调和共同提供两栋建筑。在二楼到四楼有技术设施和一个可容纳740辆汽车的停车场，停车位安排在一个中央园林庭院周围。

The sales floors are located on level -1, 0 and +1. In the basement the loading and unloading area is organized in such a way that supplying both buildings can be easily coordinated and done collectively. On the second to the fourth floor there are technical facilities and a parking lot for about 740 cars, with parking spaces organized around a central landscaped courtyard.

外观设计考虑到了用户。下面两层与商店有一个玻璃外墙，作为一个条状周围的建筑物。站立的玻璃格式和表现性形状的点击框架的外观轮廓，提供了一个强大的垂直方向。

The façade design takes the users into account. The lower two floors with the shops have a glass façade as a strip around the building. The standing glass formats and the expressive shaped click frames of the façade profiles, give a strong vertical orientation.

大楼的前三层主要是人造的“Weinlaub外观”(葡萄酒叶立面)。最初的想法，竞争，以使一个天然的过度生长的外观是进一步发展艺术和抽象。这个结构的基础是一个藤叶的抽象图像，它被自由地解释为一个三维形状。整个外观由一种类型的元素组成，即在工业热成型过程中大量生产并具有高质量。大约2900个相同的，三维形状的铝元素，画在三种不同的绿色，形成了这个独特的外观。

The top three floors of the building are dominated by an artificial "Weinlaub façade" (wine leaf façade). The initial idea of the competition to make a natural overgrown façade was developed further artistically and abstractly. The basis of the structure is an abstract image of a vine leaf, which is interpreted freely as a 3D-shape. The entire façade is composed out of only one type of element, that is produced in large quantities and high quality in an industrial thermoforming process. Approximately 2,900 identical, threedimensional shaped aluminum elements, painted in three different shades of green, form this distinctive façade.
