我们如何在一个陡峭的山坡上安置房屋？这是VG房屋项目的主要挑战，它的功能、位置和建筑都受到坡度的制约。
How can we place a house on a steep hillside? This was the main challenge with the VG house project, where its functionality and its placement and construction were conditioned by the slope.
我们必须找到最好的方法，在45度的斜坡上，面向南方，在一个狭长的土地上放置一个建筑。合理的解决方案包括在房子的不同层面设置梯田，但对于朝南的斜坡来说，这不是一个正确的决定。为了利用面向城市的景观、良好的朝向，以及从街道上释放出的视觉效果，我们决定将结构垂直于斜坡，作为一个码头，从场地的最高层出现，并分几层向下生长。
We had to find the best way to place a building on a 45 degrees slope, facing south, and in a long and narrow lot. The logical solution consisted of terracing the house’s different levels, but this wasn’t the right decision for a slope facing south. To take advantage of the views towards the city, the good orientation, and to free the visuals from the street, we decided to place the structure perpendicularly to the slope, as a dock that emerges from the highest level of the site and grows downwards in several levels.
房子所在的山坡上，完全被本地植被所覆盖。这是我们想要保留的景观亮点，为此，建筑和地面之间的关系应该得到最自然的解决，避免大的地形移动，让结构躺在植被包围的自然地形中。
The hillside on which the house is placed, it’s fully covered with native vegetation. This was a landscape highlight that we wanted to preserve, for that reason, the relations between the building and the ground should be resolved most naturally, avoiding big terrain movements and letting the structure lay in the natural terrain surrounded by vegetation.
房子的功能和内部与外部的关系，也受到山坡位置的影响。为了避免内部空间和自然地形之间的断裂感，在房子的不同楼层设置了几个露台，所有这些露台都直接与自然地形相连，允许多种扩展和不同的户外使用。
The functionality of the house and the inside-outside relations, were as well affected by the hillside placement. To avoid the feeling of disconnection between the inner spaces and the natural terrain, several terraces were placed on the different levels of the house, all of them connecting directly with the natural terrain, allowing multiple expansions and different outdoor uses.
在这样一个陡峭的斜坡上施工，也带来了一些挑战。房子的结构被设想为一个网格，作为一个永久的脚手架，使其得以建造。一个有规律的、重复的结构网格与地形相互作用，创造了两个不同的部分，一个是完全封闭的，包含了内部空间，另一个是开放的，有露台和户外扩展。其余的建筑元素（墙和板）都是预制的，并放置在一起以完成网格。
The construction in such a steep slope presented as well several challenges. The structure of the house was conceived as a grid that served as a permanent scaffold that allowed its construction. A regular and repetitive structural grid interacts with topography and creates two different parts, one fully closed that contains the inner spaces, and another open with terraces and outdoor expansions. The rest of the constructive elements (walls and slabs) were prefabricated and placed to complete the grid.
