另一排房子，另一个四人家庭，另一对父母，和另两个孩子。又是一个要接受的挑战。设计涉及到这种项目的一个特点：是翻新原有的建筑，还是拆掉它再建新的？在这种情况下，答案并不明确。一方面，由于屋顶缺乏维护，房子后面的结构已经被损坏。楼梯间也需要被拆掉，以便为停车场腾出空间（这是客户的一个不可协商的要求）。这需要一个相当大面积的新建筑。另一方面，原来的建筑有100年历史的魅力，其余的结构和建筑围墙都可以保留和翻新。
Another row house, another four-person family, another set of parents, and another two children. Another challenge to take on. The design deals with an issue that is characteristic of this kind of project: is it better to refurbish the original building or tear it down and build something new? In this case, the answer is unclear. On the one hand, the structure at the back of the house has been damaged due to a lack of maintenance on the roof. The stairwell also needs to be torn out to make room for a parking area (one of the client’s non-negotiable requests). That requires a rather large surface area of new construction. On the other hand, the original building has the charm of a 100-year-old house, and the rest of the structure and building enve-lope can be kept and refurbished.
设计策略响应了我们刚才描述的建筑的状态。所有可以保留的现有元素都没有被覆盖和粉刷。所有的新建筑–楼梯间结构、向后院的延伸以及利用斜屋顶中间的高度的新阁楼空间–都是用大规格的交叉层压木材（CLT）板完成的。这些板材没有经过任何处理。因此，新的木质元素–单一颜色、未上漆和连续的–与旧的元素（梁、瓦、砖和石膏）形成对比，后者是多样的、不规则的，并涂成白色。生活空间被分配成一个连续的新旧木材交替系列。在一楼，有一个带前庭的入口，上面有一个储藏阁楼，通往车库。门厅、一个客用卫生间和楼梯作为厨房-餐厅的缓冲区。起居室将厨房和后院连接起来。院子被划分为一个露台、一个花园和一个铺装区。在二楼，面向街道的主卧室被一个垂直的服务核心与楼梯隔开，浴室就在那里。从楼梯口，书房可以封闭，也可以开放给孩子们的卧室、带储藏室的游戏室和露台。楼梯继续向上延伸到阁楼，这是一个单一的开放空间，可以看到书房。
The design strategy responds to the state of the building, which we have just described. All the existing elements that can be conserved are left unclad and painted. All the new construction – the stairwell structure, the extension into the backyard, and the new loft space which takes advantage of the height at the middle of the pitched roof – is done in large-format cross-laminated timber (CLT) panels. These panels are left untreated. As a result, the new wooden elements – of a single color, unpainted and continuous – contrast with the older elements (beams, tiles, brick, and plaster), which are varied, irregular, and painted white. The living spaces are distributed into a continuous alternating series of old-white and new-wood. On the ground floor, an entryway with a vestibule and a storage loft on top leads into the garage. The foyer, a guest bathroom, and the stairway act as a buffer for the kitchen-dining room. The living room connects the kitchen to the backyard. The yard is divided into a terrace, a garden, and a paved area. On the second floor, the main bedroom facing the street is separated from the stairway by a vertical service core where the bathrooms are located. From the stairway, the study can be closed off or open to the children’s bedroom, the playroom with storage closets, and the terrace. The staircase continues up to the loft, a single open space that looks out over the study.
新建区域（外墙和屋顶）的建筑解决方案解决了绝缘问题，并防止了热桥的产生。新的外墙和裸露的墙体在外部覆盖了保温材料，然后进行了渲染（外部保温系统）。挤压聚苯乙烯（XPS）被安装在新的和现有的屋顶上。面向街道的立面使用干墙板和矿棉从内部进行保温。现有的楼板被加固，以减少振动，并铺上一层新的抛光混凝土作为路面。所有的窗户都被换掉了，并增加了新的可调节窗帘来控制阳光照射。房屋的能源改造和其他功能都实现了。我们觉得我们没有辜负这个挑战，因为我们解决了客户的问题，同时提供了额外的东西。
The construction solutions for the newly built area (façade and roof) resolve insulation issues and prevent thermal bridging. The new façade and the exposed party walls are covered with insulation on the exterior and then rendered (exterior thermal insulation system). Extruded polystyrene (XPS) is installed in both the new and existing roofs. The façade facing the street is insulated from the inside using drywall paneling and mineral wool. The existing floor slab is reinforced, to cut down on vibration, with a new layer of polished concrete which also serves as the pavement. All the windows are switched out, and new adjustable shades are added to control sun exposure. The energy renovation of the house and other features is achieved. We feel we have lived up to the challenge inasmuch as we have addressed the clients’ issues while offering something extra.
