内胡同的改造策略受到本地杂院居民自发的改造策略的启发。本项目入口右边原本是一条小胡同，胡同里的居民将其入口处增设了院门，使其转变为一个杂院——胡同院。

The renewal strategy of In-Hutong was inspired by the spontaneous renovation strategy of the residents living in the local hutongs. On the right side of the project courtyard was originally a small hutong (alley), at the entrance of which the residents added a gate transforming the hutong into a shared courtyard – Hutong courtyard.

鉴于天桥北部平房区在历史上就没有形成严格规制的北京四合院建筑型制，因此本地居民突破胡同——四合院的形态限制，采用灵活多样的设计手法应该受到尊重。不同于此，由于本项目的目标并非增加建筑与人口密度，因此本项目采取相反的策略，将与胡同院入口并联的原本的杂院，改造为一个内胡同，使得原本封闭的杂院空间被由外部延伸进入的内胡同重新组织。

The bungalows in the northern part of Tianqiao area did not have a strictly regulated Beijing Siheyuan architectural system in history. Therefore, the local residents breaking through the typical hutong-siheyuan morphological restrictions and renovating their residences in flexible and diverse ways should be respected. Differently, since the goal of this project is not to increase the density of buildings and populations, the idea is to adopt the opposite strategy and to transform the original shared courtyard in parallel with the entrance of the Hutong courtyard into an In-Hutong (inner alley) so that the originally enclosed courtyard space is reorganized by the In-Hutong extended from the outside hutong.

内胡同的流线与原院落的中轴线得到同等的尊重，并由此使得院落与内胡同的介面墙体获得了双重性格。这些墙体因此在面对院落与内胡同的两面获得了不同的设计，以对应稳定而宁静的院落以及流动而生动的内胡同。

The circulation of the In-Hutong and the central axis of the original courtyard are equally respected, thus the interface wall between the courtyard and the In-Hutong has a dual character. As a result, these walls have been designed differently on the two sides facing the courtyard and the In-Hutong, to correspond to the stable-and-quiet courtyard and the flowing-and-vivid In-Hutong.

由于该项目紧邻北京的南中轴线，是老北京市井文化的核心区域，拥有丰厚的历史文化。尽管该建筑作为危房被拆除改造，但是主要的空间肌理与部分无需增加保温的老墙经修缮加固后被保留下来。这些被保护的老墙体现了我们对历史的尊重，也使得天桥的历史成为看的见的历史。

Close to the south central axis of Beijing, the project is located in the core area of the old Beijing’s folk culture with a rich history. Although the buildings as dilapidated buildings were demolished and reconstructed, the main spatial texture and parts of the old walls that did not need to be insulated are retained after being repaired and reinforced.These protected old walls are the respect for history and make the history of Tianqiao a visible history.

作为北京天桥北部平房区的更新示范项目，该项目的改造经费受到很大的限制，当然这也使得这个示范项目更具现实意义。因此这个设计没有使用复杂的结构形式与昂贵的材料。仅仅使用了四种最普通的材料：木头、灰砖、钢、玻璃。建筑主体釆用北京传统木构，而提供新功能的部分：如玻璃窗、隐形空调风口等则采用钢结构与玻璃，而灰砖则因位置而定，采用传统与现代两种不同的构造做法，并承担新与旧的衔接与转译。

As a demonstration renewal project of the bungalow district in the northern part of Tianqiao, Beijing, the reconstruction budget of this project is very limited, which thus makes this demonstration project more realistic. Therefore, it is designed not to use complex structures and expensive materials but four most common materials: wood, gray brick, steel, and glass. Beijing’s traditional wooden structure is adopted for the  main body of the building, while steel structure and glass are used for the parts that provide new functions: such as glass windows, invisible air-conditioning vents, etc. The gray bricks are constructed in two different construction methods, traditional and modern, depending on its specific location, converging and translating the new and the old.

作为具体场地中的建筑更新，特别是保留了历史遗存的环境中，哪些连接历史老墙的部分在建筑语言上仍旧使用老北京本地的建造形式，而这一传统建筑形式则因现代功能的加入而被当代建筑语言形式重新组织在一起，传统建筑语言与当代建筑语言彼此对话、相得益彰。

As an architectural renewal in a specific site, especially under the circumstance where historical remains are preserved, those parts of the historical old walls were still built with the local architecture form of old Beijing in terms of architectural language. This traditional architectural form is reassembled with the contemporary architectural language form due to the addition of modern functions, thus traditional architectural language and contemporary architectural language chat and resonate with each other.
