在巴塞罗那古埃尔公园附近一栋建于1924年的建筑中，有一套带两层半地下室的公寓，本次项目旨在对这套公寓进行整体改造。该房屋位于向西倾斜的地块上，可欣赏Tibidabo山的美景。原始建筑的状况极差，房间严重缺乏光线和自然通风，不同楼层之间的关系也非常散乱。地下室实际上已经废弃多年，只能通过室外楼梯才能进入。如此糟糕的状况在需要团队给出全面干预的同时，也为他们带来了令人兴奋的挑战：将困难转化为打造极具个性的独特住宅的机会。

Project for the total renovation of a two-story semi-basement house in a 1924 building located near Park Güell, in Barcelona. The house is located in a sloping terrain with west orientation and views of the Tibidabo Mountain. The original construction was in very poor condition. The rooms were completely lacking in light and ventilation, and communication between the different floors of the building was complicated. The lower basement had been practically abandoned for years, and access was only possible via an outside staircase. This poor starting point required a comprehensive intervention. At the same time, it posed an exciting challenge: to transform the difficulties into the opportunity to achieve a unique home with a marked personality.

首先，团队决定重新定义每个空间的用途，并将不同楼层相互连通。他们选择了最适合空间衔接的自然色调手作材料来运用在五层楼中，通向室外的两个自由出口也彼此连通。地下室底层被由下至上地改造成一间可以直接通向庭院的明亮套房。为了将这层楼融入整套屋子，并为其提供一个从内部进入的通道，则必须要开凿1.2米的土地以建造新的楼梯。这种干预系统既确定了房屋的特征，也成为了其中的核心元素。挖掘工程创造出一个被裸露混凝土挡土墙环绕的双重高度空间。

The first decision consisted of redefining the uses of each space and articulating the different levels of the construction. It was then necessary to choose the materials (handcrafted and in natural shades), which were best suited to favoring the connection of the spaces and which were distributed over five floors with two free exits to the outside, connected to each other. From the bottom to the top, the lower basement was converted into a bright suite with an exit to a courtyard. In order to integrate this floor in the whole of the house and to offer it an access from the inside it was necessary to excavate 1.2 meters of land, necessary to build a staircase. This intervention completely determined the character of the house and became a central element. The excavation created a double height space, surrounded by exposed concrete retaining walls.
