In this research, authors will clarify the transformation process and the present condition of the historical block of Beijing Outer Castle as a series of researches on urban fabric. The objective of this article is to evaluate living environment of Xuanxibei district, focusing on the space formation of da-za-yuan based on field studies. Xuanxibei district is designated for ‘Cordination Area of Historic Landscape’, but also for ‘Peng-hu-qu, Area’ to be improved. The district still maintains the traditional house type called si-he-yuan, but most of them is occupied by several families. The major points which this article clarifies are the following. 1. There are many historical cultural heritages in Beijing Outer Castle where five “Historical Cultural Reserve Areas” and three “Historical Appearance Cooperative Areas” are designated. On the other hand, most of large-scale traditional courtyard house sìhéyuàn were occupided by many families and “Peng-hu-qu” which is consisted of many ‘peng-hu-fang’(small dwelling unit) was formed. Targeted study area Xuanxibei is a district designated both as a “Historical Cultural Reserve Areas” and a “Peng-hu-qu”’, and is a district that requires immediate living environment improvement. 2. In Xuanxibei district, the street network is not as neat as the inner castle at the stage of Qianlong Jingcheng Quantu(1750)and there are many vacant lands. Since the end of the 18th century, halls and the sìhéyuàn were gradually built, forming a curved street network. As of 1955, the entire district was almost completely built, and the same street network as the present was established. The street is divided into 3 levels. a street where stalls and stalls selling vegetables and fruits come and go, a street for residents to pass through, and a street leading to each dwelling house. 3. As shown in Fig. 5. The whole area is densely populated, and many of the daily activities like the public trash cans, public toilets and private storage etc. are carried out in the streets and community facilities. It is necessary to consider improvement of the living environment besides clearance type redevelopment. 4. Since the establishment of the People's Republic of China, many people flow into Xuanxibei district. As of 1955, the form of sìhéyuàn was maintained, but it gradually became a "large miscellaneous house" in which several families coexist. "Peng-hu-fang" has been rapidly increasing since the early 1960s. When moving in, it is a one-room residence or two-room residence, and then a kitchen, bathroom, warehouse, etc. are added between the courtyard and the adjacent house. 5. The district government and developers are promoting a redevelopment project, but have not progressed as planned. The forced evictions of the residents and the demolition of their homes were the main causes of the people's backlash. In addition, the number of 2287 units requested to move make it difficult to form a consensus.  It would be unrealistic to inflate all the residents and redevelop the entire district, as it would be costly to compensate. Due to the building restrictions, the volume can not be increased, and there is little benefit for developers. In order to revitalize the district, a new method of improving the living environment at the on-site may be necessary. Further investigation is needed as to what will happen to Xuanxibei district.
