▲空间视觉主体 The Boxes
项目位于巴塞罗那拉瓦尔区的中心，是一栋上下两层的老式住宅楼，因为年久失修十分衰败，在楼群之中毫不起眼。业主委托Raul Sanchez Architects进行空间重塑，希望将上层空间用来居住和休息，而下层空间则作为工作、学习、休闲的综合功能区。
The starting point was two independent dwellings on top of each other on the ground floor and mezzanine of a modest, old apartment building between dividing walls in the heart of the Raval (Barcelona). Both dwellings were in an absolute state of neglect and disrepair. The client's requirement was to concentrate the main living spaces on the mezzanine floor and expand them on the ground floor with other spaces with more diffuse functions that could be used as living room, study, work area.
▲空间视觉主体 The Boxes
设计规划清晰直观：在居室的中心，植入两个边长2米，相对空间主轴旋角45度的立方垂直体，贯穿上下两层。这两个造型完美的“盒子”，迅速成为了整个空间的主导，无须其他元素的映衬。
The proposal is clear and direct: in the middle of the space, insert two 2-meter side squares rotated 45º over the dominant axis, their vertices overlapping without touching the original walls, and extruded through both floors. A simple and resounding arrangement in which two ideal shapes, two perfect extruded squares, are imposed on the existing irregularity and arrange all the floor space without the need for any other means or elements.

其中一个盒子可以连通上下两层，承担了楼梯间的功能，另外一个盒子则分成了两个部分，上层作为卧室，下层作为洗手间和办公室。两个盒子的独特存在，为空间做出了新的区域划分，除去洗手间卧室等私密性较强的部分外无须再增加任何隔断墙体。
One of the squares will hold the stairs communicating both floors, and the other will house the bedroom on the upper floor and the toilet and office spaces on the ground floor. The very rotation of these squares results in the specialization of the space around it without needing any additional doors or enclosures (except those that provide the required privacy to bathrooms and bedrooms), since the new volumes, as they approach and move away from the perimeter walls, define these areas.

设计重点在于强调空间的平衡，用前卫的设计规划合理的功能分区和空间动线。楼梯间的外部以方形量体展示，内部则螺旋上升，用造型的对比引导体验者的情绪变化。多轴线对称的设定强调出空间的循环动线，同时增强了空间感的表达。
The proposal's emphasis runs parallel to the sought-after inner spatial complexity and a firm intention to underplay the different areas and circulation. Thus, the stairs are enclosed in one of the volumes, and their spiral pattern aims to disorient and conceal to surprise at the landings; for the same purpose, there are multiple axes of symmetry that double up circulation and enhance the spatial experience.
▲楼梯间 Staircase
为了保证上下层的联系，楼梯间与临近立面围合出了一个双层高度的垂直中庭，增强了通透感与立体感。另一边，二层空间的楼板与墙面的交接处切割出条形的长方体，并用玻璃面板补全，创建了上下层的有趣对视。
The highly reinforced top floor structure is cut off before touching the façade to reach it with a glazed floor pane, linking both floors, and thus isolating the existing façade wall, including the outer sliding carpentry are placed in that wall’s interior plane; no element touches the volumes, which are read independently inside, ending just before they touch the ceiling.

二层被两个立方体围合的封闭浴室是整个住宅最独立、私密的地方，镜面引导着视觉延伸，有放大空间的效用。为了与两个扭转了45度的立体方盒相呼应，空间的照明，门把手，淋浴头，排水管道等均随之扭转。
the enclosed bathroom area on the upper floor, the most isolated and private of the whole, mirrors and unfolds its negative space, a double-height empty area linking both floors; lights, door knobs, shower heads, drains……all elements replicate the 45° turn with respect to the surface where they are inserted ……

设计师通过对材料以及色调的运用来把控空间的层次。具有金属光泽的明黄色覆盖了两个盒子的外部，周围则是白色的包层(湿磨细水泥和油漆)。楼梯间、卧室等盒子的内部空间，选用了与白色对比强烈的纯黑色OSB木板饰面，营造视觉冲突。所有玻璃门及建筑开口框架，都选取黄铜或黑钢作为材料，门把手及五金件则为黄铜或合金。
The treatment of colors and materials highlights the two extruded volumes, which are coated in glossy, gold finish paint mixed with gold powder and varnished, surrounded by white cladding (microcement and paint) covering and coating the existing perimeters. The inside of the staircase, dug into one of the volumes, is a dark world of black contrasting with the exterior whites, just as the bed area in the bedroom, excavated into another of the volumes and covered with painted OSB wood boards and varnished in black. The door frames (all glass) and openings are either brass or black steel, depending on the area to which they give access; hinges and handles are also brass or chrome……
▲ 空间色调 The Treatment of The Color
在设计的初始阶段，设计师对建筑进行了加固和翻修，严格把控了中央区域的尺寸并进行了精确的切割。切割掉的旧木梁并没有当做垃圾处理，而是继续回收利用在空间结构里。
From the outset, the structural intervention required overhauling the foundation, high precision in placing the central squares, as well as the precise cutting of the existing wooden beams for the openings and double heights. The cut wooden beams either rest on the new steel porticos or lean on the lower wing of the new beams, always for the purpose of allowing the clean extrusion of the squares.
▲墙画 Paintings
底层保留了三幅巴西风格的画作，布置在了楼梯口。这些画既是业主的心头之爱，也是她寻乡溯源的情感依托，同时，完整诠释了这座公寓翻修改造的美好初衷。
On the ground floor, three existing paintings of Brazilian origin have been preserved, and the proposed inside circulation places them right at the stairs exit. These paintings are the reason the client, of Brazilian origin herself, initially decided to buy these two properties and undertake the project.
