Appreciations towards Vallribera Arquitectes for providing the following description:

一对环游世界的夫妇原本旅居在欧洲的其他城市，他们最近决搬回Sabadell。他们选择了父亲的故乡来养育两个孩子。他们想要住在城市中心，因而不需要车，在这里他们可以漫步或者去市场采购。比起住宅区的大院子，他们更喜欢邻里生活。

A well-travelled couple who have lived in other cities in Europe decide to return to Sabadell. They have chosen the father’s hometown as the place to raise their two children. They want to live in the city center so they won’t need a car, where they can stroll or make a quick trip to the market. They prefer neighborhood life to a big yard in a residential development.

建筑师将市中心住宅区的一栋无法再被翻新的建筑拆除。和最近的扩建的地块不同，这块地块很长但是很狭窄（具体为5.35 m宽，16.50 m长），地块的内部都是建筑，建筑师对该项目采取的最重要的决定是将庭院放置在地块的中心，而不是地块的后部。这一举措创造的立面为建筑带来通风和光照，也提供了更私密的环境，保证了与邻里之间的隐私性。建筑内的所有房间都坐落于两个体量中，向室外庭院打开，庭院也随之成为建筑的核心。

We tore down a building that could no longer be renovated on a pedestrian street in the city center. Unlike in the newer expansion neighborhoods, here the plots are wide but very shallow (specifically, 5.35 m x 16.50 m), and the block interiors are largely built up. The most important decision we made for this project was to situate the courtyard in the middle of the plot instead of putting it at the back. This operation generates an extra façade for ventilation and light, while providing a more intimate space and privacy from the neighbors. All the rooms in the house, distributed between the two built volumes, open onto this outdoor space, which becomes the heart of the house.

设计将楼梯放置在庭院之中，这里被设计成一处中间地带。庭院是一处有遮阴的室外区域，围绕着走廊和一系列的可移动的聚碳酸酯围墙，帮助建筑体量储热或降温。建筑功能被分成四个部分，两两分布在两栋体量中。在一楼，厨房餐厅与街道之间由中庭隔开，中庭内设有自行车停放区和一间客用浴室。厨房通过庭院与客厅相连。一楼一侧是儿童房和书房，另一侧是带卫生间的夫妻房。中院就像另一个房间，但没有屋顶，始终向天空、白云和阳光敞开。二楼可以在未来扩建，但现在两个大露台可以用来享受日光浴。

We placed the staircase in the courtyard, which is designed as an intermediate space. It is a covered exterior space, protected by the walkways and a series of mobile polycarbonate enclosures that help to heat and cool the two built volumes. The functional program is divided into four boxes, two in each volume, stacked across two floors. On the ground floor, the kitchen-dining room is separated from the street by the hall with a parking area for bicycles and a guest bathroom. It connects to the living room through the courtyard. On the first floor, there is the children’s room and the study on one side and the couple’s room with the bathroom, on the other. The courtyard at the center, like another room but without a roof, is always present, open to the sky, the clouds and the sun. The second floor is ready for a possible expansion of the house in the future, but for now, the two large terraces can be used for sunbathing.

设计植入了简单的生态气候策略。住宅的两个部分作为集约、隔热良好的建筑互相独立运行。但同时，它们的功能在不同的楼层也是分开的。这样就形成了四个紧凑的空间，对空调的需求也被降到最低。在夏季的夜晚，庭院带来了持续的微风来为建筑降温，百叶窗遮挡住光照，爬山虎也帮助散热。在冬季，走廊持续延伸到二层来捕捉更多的阳光，作为一个太阳能收集器，将预热后的空气输送到整个室内。当每年的极端天气来临时，可以通过最小容量的热汞来调节室内温度。

We implemented a simple bioclimatic strategy. The two parts of the house function independently as compact, well-insulated buildings. At the same time, their uses are segregated across the different levels. The result is four compact spaces that have a minimum demand for air conditioning. On summer evenings, the courtyard guarantees a constant breeze to cool the building, the rolling blinds keep out the sun, and the climbing plants help dissipate the heat. In winter, the gallery, which extends to the second floor to seek the sun, acts as a solar collector and distributes the preheated air throughout the house. For the days of the year when the temperature is most extreme, the temperature can be controlled by a minimum capacity heat pump.

建筑师采用传统结构的承重墙，单向的楼板和预制长方形梁架。结构砖在Segrià县制造，立面由内部有保温材料和空气间隙的空心砖构成，有助于通风。采用这种系统意味着砖块的外立面暴露在外，但内部可以重新粉刷。一层的水泥天花，连续的混凝土地板和二层的镶木地板垫定了室内设计的基调。楼梯和走廊由轻型金属框架和经过压力处理的松木板构成。没有装饰的原始材料和不同颜色的元素组合在一起，例如绿色的窗户，粉色的薄荷厨房和浴室橱柜，家具结合了暖色调的原木和明亮色彩（黄色，红色和橘色）。

We worked with a traditional structure of load-bearing walls and floor slabs running in a single direction, with prefabricated rectangular beams. The construction is of structural brick manufactured in the county of Segrià, with the façades made from cavity brickwork with insulation and an air gap for ventilation. Using this system means the brick can be exposed on the outside and painted on the inside. Plaster ceilings, continuous concrete flooring on the ground floor, and parquet flooring on the first floor define the interior design. The staircase and walkways are a lightweight construction made from metal profiles and pressure-treated pine planks. The raw presence of the materials, with no cladding, is complemented by elements of different colors such as the green windows, the pastel mint kitchen and bathroom cabinetry, and the furniture that combines the warmth of natural wood with touches of bright colors (yellow, red and orange).

我们不时都需要小王子来提醒我们：“最重要的是那些看不见的事物。” 旅居海外，这家人了解到：他们希望新家可以符合他们的价值观。这是他们对于奢侈的定义，而这个项目也为他们提供了新的家园。

From time to time, we all need a Little Prince to remind us that ‘the most important thing is invisible to the eyes’. Living abroad, the family came to understand something: they wanted a new home in harmony with their values. That is their definition of luxury, and this project has offered them that new home.
