Located on a hilly intersection in Bairro Alto, a picturesque, maze-like quarter of Lisbon, this historic three-storey townhouse has been adroitly converted by local practice SIA arquitectura into two interlocking yet distinct residences that share a sunny courtyard. Taking its name from Rua de São Marçal, the street it’s situated on, the project involved the accommodation of two contemporary homes with minimal interventions to the centuries-old building fabric and respect to the building’s architectural heritage. In response to this challenging brief, the architects have opted for a clever configuration of quaint yet functional spaces while adopting a minimalist design language that seamlessly marries the historic architectural features with the modern furnishings inside.

这栋历史悠久的三层联排别墅位于里斯本风景如画的迷宫般的里斯本区Bairro Alto的丘陵交叉口，已被当地实践SIA arquitectura巧妙地改造为两个相互联锁但截然不同的住宅，共享阳光明媚的庭院。该项目以其坐落的街道Rua deSãoMarçal的名字命名，涉及了两栋现代房屋的住宿，而对百年历史的建筑结构和建筑物的建筑遗产的干预却很少。为了应对这一具有挑战性的简介，建筑师选择了巧妙而古朴而又实用的空间配置，同时采用了极简主义的设计语言，将历史建筑特色与内部现代家具无缝融合。

Taking advantage of the building’s corner location, the entrances to the two residences are located on different streets. “Casa Térrea”, or the Ground House, takes up the building’s ground floor and part of the first floor, while “Casa Alta”, or the High House, occupies the majority of the first floor and the second-floor attic. Entry to the Ground House is through a vaulted vestibule which is flooded with daylight courtesy of a glazed archway that provides access to the shared courtyard at the back of the building. Designed as a succession of spaces, an elongated corner room that functions as a living and study area, leads to the sitting room and the kitchen - also connected, while a feature bookcase-cum-staircase leads to the children’s bedroom upstairs, while the master bedroom situated on the ground floor on the other side of the vestibule. Featuring an all-white colour palette and a complete lack of decorative features, the Ground House’s stark minimalism is balanced by a rich vocabulary of volumetric geometries that highlight the building’s idiosyncrasies or introduce modern counterparts. Besides the vaulted vestibule, features like these include a cylindrical shower room, a pyramid-shaped ceiling, cubic wardrobes-cum-partitions, and a wooden staircase that forms a prismatic volume aligned with the aforementioned bookcase.

利用建筑物的转角位置，两个住宅的入口位于不同的街道上。“ CasaTérrea”或“底层房屋”占据建筑物的底楼和一楼的一部分，而“ Casa Alta”或“高级房屋”则占据一楼和二楼阁楼的大部分。进入地下室是通过拱形的前厅进入的，该天井由玻璃拱门提供日光照射，可以进入建筑物后方的共用庭院。设计为一连串空间，一个细长的角房用作起居室和学习区，通向客厅和厨房（也相连），而书架兼楼梯组合通向楼上儿童卧室，而主人卧室位于前厅另一侧的一楼。拥有全白色的调色板和完全没有装饰性的特色，Ground House的鲜明极简主义与丰富的体积几何词汇相得益彰，这些词汇突显了建筑物的特质或引入了现代的对应特征。除了拱形的前厅外，类似的功能还包括圆柱形淋浴房，金字塔形的天花板，立方壁橱兼隔板，以及形成与上述书柜对齐的棱柱形体积的木制楼梯。

While the all-white colour palette continues in the High House, here the minimalist aesthetic is tempered with dark parquet flooring and classic furniture pieces. Crowned by a circular skylight, a staircase connects the ground floor entrance to a large, bright living and dining area on the first floor and the attic above. With views onto the street and the courtyard in the back, the first floor living room is undoubtedly the heart of the house, with a bedroom and the kitchen on either side. Accommodating three small bedrooms that open up onto a shared playroom, the second floor attic is characterised by the interlocking pitched roof and dormer windows that form a sculptural ceiling-scape. Swathed in white, the prismatic complexity of the attic roof reflects the character of the historic building and imbues the house with an unexpected playfulness which in combination with the minimalist interior design language subtly bridges both past and present.

虽然高屋子继续采用全白色调色板，但这里的简约美学却因深色镶木地板和经典家具而得到了缓和。楼梯由圆形天窗加冠，将一楼的入口连接到一楼和顶楼的宽敞明亮的起居和就餐区。一楼起居室无疑是房屋的心脏，可欣赏街道和后院的景致，每侧都有一间卧室和一间厨房。二楼阁楼可容纳三间通向共用游戏室的小卧室，其特点是互锁的斜屋顶和天窗，形成雕塑般的天花板景观。裹成白色，
