　　Peter Pichler建筑事务所设计的位于荷兰马尔森的一座35000 m²的塔式高层复合住宅建筑，赢得了一项国际邀请赛。

　　这座复合建筑由大约260套公寓、停车场、公共设施、体育馆和屋顶跑道组成。它位于阿姆斯特丹和乌得勒支之间的主轴线上，是该地区的社会“引擎”，在未来几年将会有重大发展。

　　Peter Pichler Architecture won an international invited competition for the design of a new residential tower complex of 35000 m² in Maarssen, Netherlands.
The new complex consists of approx. 260 apartments, parking garages, public facilities, gym and a running track on the roof. It is located on a main axis between Amsterdam and Utrecht and should act as a social “engine” in the area, which will undergo some major developments within the next years.

　　设计概念

　　Peter Pichler建筑事务所建造两座looping towers的提议，充分考虑到视野和光照得出的优化几何结构，保证从后面的办公室也可以看到河流和马尔森老城区中心景观。细长的L形几何形状是为了适应场地的特殊情况(北侧看景观，南侧向阳)和公寓方位，保证了多样的视野和光照。两座倾斜的L型塔交错分布，这两座相邻的建筑都因此获得更好的视野，且受到的阴影影响最小化。自然形成的露台获得了朝向老城区的多样化视野，并在白天接受最大限度的阳光照射。

　　CONCEPT

　　PPA´s proposal for two looping towers are the result of an optimized geometry based on views and sunlight. Starting point were massing studies of straight extrusions that are moved towards the end of the plot to guarantee the view from the offices behind towards the river and the old city center of Maarssen. The special situation of the site (north side with view, south side sunlight) and the unsophisticated orientation of the apartments within a straight extruded tower with central core led to a slim L shaped geometry that guarantees multiple views and sunlight. While sloping back the L shaped towers with the lower tower on the west side, better views are generated for adjacent buildings with a minimum shadow impact. The  naturally formed terraces generate multiple views towards the old city and achieve a maximum sunlight during the day.

　　在平台层，两座塔连接成一个循环，在中间形成了绿色公园。交错的平台处有护理服务中心和公共设施，如带有跑道的屋顶体育场。

　　公寓大多数做成复式，以保证双侧视野，这种复式结构也表现在立面上，越靠近街道平面结构越封闭，越靠近顶部则越开放。

　　At the podium level the two towers connect in a loop that steps back to create green parks. The interweaving podium strings contain care housing as well as public facilities such as the gym with a running track on the roof.
Most of the apartments are conceived as duplex in order to guarantee the double side view and to have an optimized ratio between GLA and circulation. The duplex typology is expressed in the facade as well which fades from a more closed structure at the street level and opens towards the top.
