为此，创建了一个紧凑的三级卷。几何图形直接产生于给定的几何图形和坡度，重新诠释了该地点的土木建筑的美学及其倾斜的屋顶，扩大了上层的面积，以获得一些额外的面积。

To achieve this, a compact three level volume was created. The geometry arises directly from the plot given geometry and slope, reinterpreting the aesthetic of the site’s vernacular architecture with its sloped roof, widening on the upper floors to gain some additional area.

在形式上，体积是一个立方体，每个面都被分成四个象限。上表面向上挤压形成屋顶。侧脸旋转，描绘重要的风景时刻，注意邻居的隐私。

Formally the volume is a single cube in which every face has been divided into four quadrants. The upper faces are extruded upwards to form the roof. The side faces rotate to frame significant scenic moments, mindful of the neighbors’ privacy.

外观由一个连续的皮肤组成，为墙壁、屋顶和开口提供了同样的无光泽的白色外观。固定的窗户是由玻璃窗构成的，与正面完全平齐，而操作的窗户有一个白色的穿孔铝快门，也安装了与皮肤同花顺的铝制快门。

The façade consists of a continuous skin that provides the same matt white aspect to walls, roofs and openings. The fixed windows are made of glass panes totally flush with the façade, and the operating ones have a white perforated aluminum shutter also installed flush with the skin.

在地块的低端有一个穿孔的Corten钢前篱笆，让行人和汽车进入该物业。外部空间由两个梯田构成，斜坡区形成三角形坡道。路面采用多种颜色的板条，典型的是这一地区，平面区域采用长而窄的瓷砖，而坡面上则采用较小的不规则块。

A perforated Corten steel front fence at the low end of the plot gives pedestrian and car access to the property. The exterior spaces are formed by two terraces and the sloped areas have been modeled forming triangulated ramps. Pavements are made in multicolored slat, typical of this area, using long narrow tiles for the plane zones, and smaller irregular pieces on sloping ones.

入口处由第一宿舍、浴室和设有餐厅的厨房组成。厨房是一个双高空间，有两扇大窗户，可以俯瞰山谷。在楼上有主卧室和它的浴室，两者都指向位于地块背面的松林。半埋低层由技术和储藏室、起居室和工作室组成，两者都有通往花园的通道。

The entrance level is composed by the first dormitory, the bath and the kitchen with a dining room area. The kitchen is in a double  height space with two large windows that offer the best views over the valley. In the upper level there is the master bedroom and its bath, both oriented to the pine forest at the back side of the plot. The semi-buried lower floor is formed by the technical and storage rooms, a living room and a studio both with access to the garden.

在房子的内部，地板和浴室的墙壁被卡普里天然石头覆盖，墙壁和门用象牙白色油漆完成。在双高区，大型内置深色榆树家具建造厨房和餐饮区的墙壁家具和岛屿，上升到上层，形成主宿舍橱柜。

In the interior of the house the floors and bathroom walls are covered with Capri natural stone and the walls and doors are finished in ivory white color paint. In the double height area, large built-in dark tinted elm furniture builds the kitchen and dining area wall furniture and the island, ascending to the upper floor to form the master dormitory cupboards.
