1 東立面/East facade

住宅地處俯瞰著奧地利福拉爾貝格的施林斯村。

該住宅的選材與造型在景觀環(huán)境中直接呼應著狹長場地的南向坡地特征——仿佛用土壓成的一尊以人工抽象自然的巨石。

兩條裂口表達出夯土建筑的特征，使其向后靠近峭壁，并面向山谷形成了一種朝前歡迎的姿態(tài)。住宅的室內采用多個序列形式，以對應各層不同的狀況。

不同于更有機、古老的粘土建筑，這座建筑的形態(tài)意在表達清晰和尖銳。插在特有的粘土層之間的泥磚帶通過強調水平性并突出表面肌理的光影效果，使建筑在視覺上更加穩(wěn)定。在材料與氛圍的層面上，這個空間序列通過不同處理過程的均衡疊加，真實地體現(xiàn)出從原始質樸到雄壯不凡的演進。

從整體上看，這座住宅就像一個實驗建筑，體現(xiàn)出建筑師羅杰·博爾茨豪瑟與夯土建筑大師、客戶馬丁·勞奇之間密切的設計合作，而經后者親自動手建造則是這座建筑最大的亮點。□（尚晉 譯）

2 總平面/Site plan

The site for the residential house oversees the village of Schlins in Vorarlberg, Austria.

The materiality and form of the residential house are direct reactions to the steep south-sloping situation of the slender plot in a landscape context -as if a monolithic block, similar to a piece of abstract and artificial nature, had been pressed out of the earth.

Two clefts articulate the building of rammed earth, wedging it backwards with the scarp and establishing a frontal prelude or welcoming gesture towards the valley. The interior of the house is developed in the form of sequences of spaces that respond storey-wise to the variable conditions.

As opposed to more organic, archaic clay architecture, the morphology of the building aims towards a certain clarity and sharpness. The strips of clay bricks that are inserted between the typical clay layers optically stabilise the building structure by emphasising the horizontality and heightening the light and shadow effects of the surface texture. At a material-atmospheric level the spatial sequence shows a succession that literally ascends from the raw and archaic to the distinguished splendour through a balanced overlaying of different treatment processes.

Taken as a whole, the house is a laboratorylike experiment, depicting the close planning cooperation between the architect Roger Boltshauser and the master clay builder and client Martin Rauch, culminating in his own hands-on construction of the building.□

評論

劉珩：該建筑的承重外墻以夯土筑成，并插入勻質的薄磚帶作為防腐處理。內部厚重的夯土結構借由植物纖維和粘土灰漿達到絕緣的效果。梁和樓板結構放置于夯土外墻上。內部樓梯間體現(xiàn)了夯土的絕佳質感，中和了水泥在其他空間的應用。旋轉而上的踏步串聯(lián)起3層空間，飄逸的黑色金屬擋板這樣現(xiàn)代的材料，與古樸質感的夯土形成對比。連接方式上刻意弱化了金屬擋板的受力，使其像是漂浮在樓梯踏步之上，迎合并突出了樓梯間向上的動勢。夯土體系的運用，與室內功能以及其他表面處理有機銜接，讓空間得以從容、得體、自然和多變。

穆鈞：業(yè)主的身份和作為自宅的項目性質，使馬丁·勞奇能夠獲得相對寬裕的自由度，將自己多年的夯土營建經驗加以總結，并在建筑師羅杰·博爾茨豪瑟的支援下進行更具系統(tǒng)性的應用探索。生土，作為就地可取的自然材料，以不同的形式被充分地運用于墻身、樓地面、內飾面、樓梯等一系列建筑要素。尤其值得稱道的是，源于地方傳統(tǒng)的夯土營造工藝，與現(xiàn)代建筑空間以及結構體系有機地融合在一起，而其在力學和耐水性能方面固有的局限性，通過一系列富有創(chuàng)造性甚至開創(chuàng)性的構造設計與施工工藝革新，得到了有效的克服或規(guī)避，使生土材料所具有的生態(tài)應用潛力及其相應的建筑語言，得到了淋漓盡致的發(fā)揮。不論在國際現(xiàn)代夯土建筑還是在綠色建筑領域，勞奇自宅作為一個實踐探索的典范，具有普遍公認的里程碑意義。

Comments

LIU Heng:The load-bearing exterior walls are built with rammed earth, inserted are evenly thin band of tiles as erosion checks, while the interior massive rammed earth building is insulated with reed and finished with clay plaster. The beams and floor constructions rest on the exterior rammed earth walls. The staircase reveals the texture of rammed earth inside, counteracting to other plastered spaces. The oval spiral staircase connects all three levels. The use of the elegant and smooth black metal balustrade forms a contrast to the archaic and rammed earth. The inner metal balustrade is not connected to the stair, so the balustrade appears to be floating on the steps. The rammed-earth system, comprehensively connected with the interior functions and other treatments, makes the spaces leisurely, appropriate, natural, and varied. (Translated by WANG Xinxin)

MU Jun:The nature of the project as the masters clay builder's own residence has granted Martin Rauch relatively ample freedom to concretize years of earth-based construction experience, while support from architect Roger Boltshauser facilitates more systematic exploration for further application. Raw Earth, as a locally sourced natural material, has been extensively used for various building elements such as wall, floor, interior finish and staircase. It is particularly worth mentioning that the rammed-earth technique which has originated from local traditions can be organically integrated with modern architectural spaces and structural systems. In this manner, its inherent limits on mechanical and waterproofing performance can be effectively overcome or avoided by means of various creative or original tectonic designs and innovations in construction, so that the ecological application potentials and the corresponding architectural language of earthen material be full-blown. Whether in the field of advanced earthen architecture or in that of green architecture, House Rauch is universally recognized as a milestone for its exemplary exploration in construction practice.
