L宅是一栋独栋别墅，包含一个办公室和一个互惠生的公寓，被雕刻成一块巨大的混凝土。它就像它的外表一样：内部和外部都是混凝土，没有进一步的绝缘或覆层。
House L, a single-family house containing an office wing and an apartment for an au pair, is sculpted as a monolith of massive concrete. It is as it appears to be: inside and outside concrete, without further insulation or cladding.
它的晶体形式来自于周围的建筑：30年代的紧凑型单体房屋，带坡屋顶，位于大花园的角落。在这里，这个六边形的物体是有角度的，以便在西北方向为车库留出空间，并允许在南边有一个宽敞的花园。
The crystalline form takes its cues from the surrounding buildings: compact single houses from the 1930s with hipped roofs standing at the corner of large gardens. Here, the six-sided object is angled to leave space on the northwest for the garage and to allow for a spacious garden to the south.
该计划是围绕一个菱形的楼梯间展开的，它是承重的核心，并整合了中央服务井。各个房间都围绕着这个中心要素排列，每个房间都向不同的外部空间开放。
The plan is developed around a lozenge-shaped stairwell, which is the loadbearing core and integrates the central servicing shaft. The rooms are arranged around this central element, each opening out onto different outside spaces.
在一楼，厨房紧挨着起居/用餐区，并向东侧的露台开放。在厨房区后面是一个供互惠生居住的小公寓，有自己的入口和东北部的小型私人花园空间。储藏室和衣帽间等辅助空间与互惠生房间和厨房相互连接，同时直接通向车库。
On the ground floor, the kitchen abuts onto the living/dining areas and opens up towards a terrace on the eastern side. Behind the kitchen area lies a small apartment for an au pair, with its own entrance and small private garden space in the northeast. The ancillary spaces such as storage and cloakroom are interconnected with the au pair room and the kitchen while opening directly onto the garage.
上层安排了儿童卧室、主卧室和客房，另一边是办公空间。办公室的主要入口是一个从主车道上去的独立楼梯，但也可以从屋内进入。最南边的房间可以灵活地添加到办公室组合中，或者作为私人住宅的儿童房使用。
The upper level is organized with the children’s bedrooms, the master bedroom and the guest room on one side, and office space on the other. The office has its principal entrance from a separate stair leading up from the main driveway but can be also entered from inside the house. The southernmost room can be added flexibly either to the office ensemble or used as a children’s room in the private house.
V形楼梯的采光井直通地下室，那里有游泳池、蒸汽浴室、桑拿房和健身室，向东侧的下沉式花园开放。
The light well of the V-shaped staircase tunnels down to the basement, where a swimming pool, steam bath, sauna, and fitness room open onto a sunken garden on the east side.
底层平面有一个多边形但紧凑的形式，塑造了内部房间、花园区域和折叠式屋顶。
The ground floor plan has a polygonal but compact form that shapes the interior rooms, the garden areas, and the folding roof.
形式的统一性反映在材料的统一性上。红外线混凝土的厚厚的自保温墙面是光滑的，表面有纹路，而屋顶的底面用粗木板的百叶窗来装饰，强调了各种表面的方向。对角线百叶窗贯穿到入口区地面的乳白色多边形瓷砖上。这些柔软的表面辅以中性色调的乳白色石膏、灰色石材和地毯，以及自然色调的橡木和烟熏橡木的家具。
The unity of form is reflected in the unity of material. The thick self-insulating walls of infra light concrete are smooth with a veined surface while the roof’s underside is finished with a shuttering of rough planking, underscoring the directions of the various surfaces. The diagonal shuttering is carried through onto the cream-white polygonal tiling on the entrance area floor. These soft surfaces are supplemented with neutral tones of the cream-white plaster, the grey stone and carpet, and the natural tones of oak and smoked oak of the furnishing.
上层表面用密封胶进行保护，因为经过仔细检查发现，原先设想的裸露的混凝土本身并不足够耐用。表面用液体聚合物防水剂覆盖，洒上火烘干的石英砂，颜色斑驳，模仿红外光的混凝土，而混凝土本身又覆盖着散乱的暗色孔隙。墙的底部用与混凝土颜色相同的矿物水泥浆保护。
The upper surface is protected against the elements with a sealant, after a closer examination showed that the naked concrete itself, as originally envisaged, would not be sufficiently durable. The surface is clad with liquid polymer waterproofing, sprinkled with fire-dried quartz sand of mottled colours which mimic the infra light concrete which itself is covered with a scattering of dark pores. The base of the wall is protected with a mineral cement slurry in the colour of the concrete.
