Planas i Casals – Triomf 7住宅改造丨Sau Taller d’Arquitectura

本项目旨在对位于巴达洛纳Carrer del Triomf与Carrer de Planas i Casals街角的两栋20世纪初联排住宅进行翻新与扩建，将其转化为一栋三层、包含7套住宅的居住建筑。各住宅单元围绕一个中央服务核心组织，并通过新的立面开口面向街道，这些开口在比例与尺度上延续了原有建筑的特征。最终形成的住宅建筑融入既有城市肌理，强调场所的历史记忆，同时提升整体居住条件。

The project aims to refurbish and extend two early-20th-century terraced houses located on the corner of Carrer del Triomf and Carrer de Planas i Casals in Badalona, transforming them into a residential building with seven dwellings distributed over three floors. The apartments are organized around a central service core and open onto the streets through new façade openings that preserve the proportions and dimensions of the original architecture. The result is a residential building that integrates into the consolidated urban fabric, highlights the historical memory of the place, and improves overall living conditions.

保留既有结构

PRESERVING THE EXISTING STRUCTURE

项目有意识地尽可能保留原有构件。立面与室内承重墙均被保留。为实现这一目标，基础通过微型桩进行加固，并在内部引入了一套新的钢结构体系。该结构由HEB与IPE型钢构成框架，并结合组合金属楼板，承担双重作用：一方面减轻原有陶砖砌体墙的结构荷载，另一方面提高建筑抵抗水平力的稳定性。

The project makes a conscious effort to retain as many existing elements as possible. The façades and the interior load-bearing walls are preserved. To make this feasible, the foundations were reinforced using micropiles, and a new internal steel structure was introduced. This structure, formed by a framework of HEB and IPE profiles combined with composite metal deck slabs, serves a dual purpose: relieving the original ceramic masonry walls of structural loads and stabilizing the building against horizontal forces.

功能与秩序

FUNCTIONALITY AND ORDER

楼梯沿与相邻建筑的共用墙布置，从而最大程度释放立面，以确保住宅获得更好的自然采光与通风。既有的中央墙体被保留，作为垂直交通核心与住宅之间的分隔构件。该核心集中布置了更为技术性的功能（如卫生间、设备管井、电梯等）。这一策略不仅释放了立面，也为住宅内部布局提供了灵活性，使其能够适应不同的使用方式与需求。

The staircase is positioned along the party wall with the neighboring building, freeing up the façades as much as possible to ensure better natural lighting and ventilation for the dwellings. The existing central wall is preserved and acts as a separating element between the vertical circulation core and the apartments. This core concentrates the more technical components (bathrooms, service shafts, elevator, etc.), a strategy that not only frees the façade but also provides flexibility in the interior layout of the dwellings, allowing them to adapt to different uses and requirements.

形式策略

FORMAL STRATEGY

阳台与窗台等关键既有元素被保留。原有窗户与法式门的竖向比例亦得以延续，并指导新开口的设计，从而确保每个房间均具备自然采光与通风。立面墙体顶部以小型檐口收边，延续周边建筑的构图策略。同时引入了一系列小尺度钢制阳台，作为清晰可辨的当代介入。这些阳台为住宅的共享空间提供室外延伸，也为整体较为严谨的立面构图增添了一丝细微的动感。

Key existing elements such as balconies and window sills are preserved. The vertical proportions of the original windows and French doors are also maintained, guiding the design of new openings that ensure natural light and ventilation in every room. The façade walls are finished with a small cornice, following the compositional strategy of the surrounding buildings. A series of small steel balconies are introduced, clearly identifiable as contemporary additions. These provide outdoor access for the shared spaces of the dwellings and add a subtle sense of movement to an otherwise very rigorous façade composition.

室内

INTERIORS

在室内，钢结构被保留为外露状态并涂以白色，为天花增加了层次与质感，同时将光线反射至室内空间。该结构与原有陶砖砌体墙体之间形成清晰区分。整体室内设计围绕两种主要元素展开：白色与木材。白色用于墙面、光洁的天花与钢结构，以及定制家具（门、厨房等）；木材则应用于地面、窗框与阳台框架，以及厨房与卫生间中的局部构件。

Inside, the steel structure is left exposed and painted white, adding texture and depth to the ceilings while reflecting light into the interior spaces. Once again, this structure is clearly distinguishable from the original ceramic masonry walls. In essence, the interior design works with two main elements: white and wood. White appears on the walls, the glossy ceilings and steel structure, and the built-in furniture (doors, kitchens, etc.). Wood is used in the flooring, window and balcony frames, and in selected elements within kitchens and bathrooms.

项目在保留历史遗产与引入当代元素之间取得了平衡，从而提升了居住的功能性与生活品质。材料的组合、结构的可读性以及对自然光的细致处理，使得在不丧失建筑原有身份的前提下，能够创造出符合当代生活的居住空间——表明审慎而周到的更新既可以具有创新性，也能够回应其所处的城市语境。

The project achieves a balance between preserving historical heritage and introducing contemporary elements that enhance functionality and quality of life for residents. The combination of materials, the legibility of the structure, and the careful attention to natural light make it possible to create modern homes without losing the building’s original identity—demonstrating that thoughtful rehabilitation can be both innovative and sensitive to its urban context.
