室内空间的拓展：“双胞胎”住宅

该项目位于里斯本以南30公里处的小渔村Sesimbra，在一个距离海边600米的大坡地上，从村子一直延伸到城堡，被一片松林和一条公路所包围。这里的风景有一种野性的Cycladic之美和令人神往的海景。橄榄树、无花果和阿勒颇松生长在曾经用于农业的干旱岩石土壤上。

This project is located in Sesimbra, a small fishing village 30km south of Lisbon, on a large, sloping site 600m from the sea, which extends from the village to the castle and is bounded by a pine forest and a former Roman road. The landscape here has a wild Cycladic beauty and breathtaking views of the sea. Olive trees, figs and Aleppo pines grow on arid rocky soils, once used for agriculture.

我们的客户是两姐妹，她们想把这所60年代建造的小房子改造成度假屋，让她们的家人和朋友在夏天可以聚在一起。我们的第一个决定是在两个独立的体量中建造一个新住宅，为每个家庭提供自主权，就像双胞胎一样，他们有共同的属性，但表达自己的方式也略有不同，一个更高，开放，暴露在景观中，另一个更水平，寻求与周围土地的亲密关系。

Our clients, two sisters, wanted to convert a small house built in the 60's into a holiday home, where their families and friends could gather in summer. Our first decision was to build a new house in two separate volumes, providing autonomy for each family. Like twins, they share properties but each also expresses itself in a slightly different way; one higher and open, exposed to the landscape, the other more horizontal, seeking an intimate relationship with the surrounding land.

由于法律规定的最大建筑面积为250平方米，我们在每栋房子周围插入了庭院，并创建了一个大顶棚，将室内延伸到室外，并产生了额外的室外区域，通过在顶棚种植绿植提供遮阳。一个6米深的悬浮结构漂浮在房屋周围，由电缆和电线编织而成，创造了一个巨大的户外客厅，可以俯瞰大海，全家人可以在这里聚会。

As legal restrictions set 250m2 as the maximum floor area, we inserted courtyards and created a large canopy around each house, extending the interior to the exterior and generating additional outdoor areas, with planting overhead to provide shade. A 6m deep, suspended structure floats around the houses in a filigree of cable and wire, creating a largeoutdoor living room, which overlooks the sea, where the whole family can meet.

要形成这样的景观需要一种特殊的材料氛围：强烈而粗糙，因此必须用强烈而感性的原材料制成。嵌入地下的房子似乎是从岩石中冒出来的。我们用褐色赭石颜料制成的彩色混凝土不断进行试验，直到找到与周围土壤相同颜色的混凝土。其表面光秃秃的集合体，粗糙而光滑，像石头或动物的皮，为得到这一纹理，混凝土在傍晚浇注，采用化学方法推迟表面砂浆的凝固，并在清晨冲洗干净。

This special landscape called for a specific atmosphere: intense and rough, made of strong and sensual raw materials. Embedded in the ground, the houses appear to emerge from the rock. Colored concrete was used, created with brown ochre pigments, tested endlessly until an identical color to the surrounding earth was found. Its surface, with exposed aggregates, is both rough and smooth, like stone or an animal skin. To obtain this texture, the concrete was poured at dusk, using a chemical process to delay the surface mortar from setting, washing it off at early dawn.

在室内，所有的元素都被减少到最低限度，材料保持自然状态，只有墙壁被粉刷过。窗户和百叶窗完全滑入墙壁，将整个房子变成一个外部空间。开放时，吃饭、睡觉和洗澡都在室外进行，在微风的吹拂下躲避太阳。

Inside, all elements are reduced to a minimum, materials are left in their natural state and only the walls are painted. Windows and shutters slide completely into the walls, transforming the whole house into an exterior space. When open, eating, sleeping and bathing take place outdoors, sheltered from the sun with a breeze passing by.

混凝土元素被放置在场地的特定位置。长椅、平台和圆形水池定义了大自然中的小空间，在景观中创造了独特的时刻。在夏天，隐藏在本地植物中，一棵夜来香和一棵罕见的桉树为这个地方增加了一种神奇的气息。

Concrete elements are placed at particular points on the site. A bench, a platform and a circular pool define small spaces in nature, creating unique moments in the landscape. In summer, hidden among the native plants, a cestrum nocturnum and a rare eucalyptus citriodora add an olfactory, magical dimension to the place.
